Small performance fans for boiler rooms. Types and functions of fans for solid fuel boilers. Why do you need a fan. Its main functions

Previously, traction and blowing fans were used only in industrial boiler installations. The first is set inside the chimney channel and create a vacuum, the second - the air is injected into the furnace. Gradually, the aggregates moved to the household sphere - manufacturers began to equip heaters with a closed combustion chamber by turbines. The idea was picked up home craftsmen, because the smoke for a solid fuel boiler is able to solve the problem of bad thrust in the discharge tube. Let's figure it out, whether a forced hood is always necessary.

The factory exhaust fan includes the following elements (the device is shown in the diagram, the positions coincide with items):

Metal heat-resistant impeller with blades, bent under 90 ° relative to the impeller.
Fastener.
Electric motor with low performance (20 ... 50 W).
Power cable connector.
The console with controls and controls.
The flask and the capillary tube of the temperature sensor connected to the emergency thermostat.
Network wire with a fork.

Note. As an example, the Kalvis DM-01 Boiler Firms is taken. The design of other types of fans is distinguished by the body shape - snail, box, hemispherical landing site. Set of details similar.

The unit is attached to a special box located on the back of the household TT-boiler near the flue of the chimney. The flask of the temperature sensor is inserted into the immersion sleeve water shirt, the remote is placed separately.

The principle of operation of the smoke is the forced tap of high-temperature gases from the heat-tube heat exchanger of the boiler in the chimney. The algorithm looks like this:

The fuel is filled with firewood, ignition is produced.
The loading door locks down, confused - opens. The fan turns on the key on the console, then the performance is configured.
When the heating installation and chimney warms up, the impeller speed manually decreases to a minimum. If the heat generator is enough natural traction, the smoke is recommended to disable.
When the heat carrier is heated to a critical temperature of 100 ° C and more on the sensor command, an alarm thermostat is triggered, which turns off the fan automatically.

Scheme of work of boiler smoke

Reference. On TT-boilers, equipped with automatic thrust regulator, do not need to break the door of the roller. The thermostat by chain will open the air supply damper to the desired angle.

Large or low productivity of the traction fan is exhibited individually depending on the quality of solid fuel, combustion mode and degression of chimney. The main thing is to avoid accumulating and leaking smoke to the room.

Almost can be removing with turnover - the lion's share of warmth will go into the pipe. Before opening the door and reloading the speed of rotation is better to increase to the maximum.

The finished fan block of the famous Russian barn Zota is mounted on wood heaters with rear gases

For boilers on solid fuel and wood fireplaces, several types of smokers are sold:

boiler (design considered above);
centrifugal channel;
overhead;
fireplace / oven (it is roof).

Various nozzles that improve natural cravings are not included in the smoke, are deflectors, round rotary elements and rotating flugers. The effectiveness of these caps depends on the wind load, which changes with the weather.

Dimensions of channel smoke, some models are equipped with temperature sensors

The channel fan is distinguished by its own body with two connecting flanges or nozzles. The unit is installed vertically or horizontally into the gap of the chimney pipe. The device and principle of operation is similar to the operation of the boiler hood.

The overhead smoke for the household boiler is equipped with a semicircular platform and locks - screeds. Installation is made on the vertical section of the chimney (displeased):

On the paper template in the pipe is cut out the opening.
The impeller of the traction machine is inserted into the hole, the platform with the electric motor presses to the surface by the locks.
The compound is compacted due to asbestos cord, glued to the inside of the smoke mounting site.

Note. The invoicing element is selected by the diameter of the gas duct. The installation process is shown on video.

Electric hoods for fireplaces are planted on the head of the brick chimney and are attached to the spacer bolts. The power cable is paved along the pipe and is entered into the room next to the home furnace.

To choose a traction machine, you need to navigate 3 criteria:

the power of the heat generator, the smoke models calculated the capacity of boilers to 20, 30, 50 and 100 kW;
installation point - on the bolet itself, pipe or glove;
for false models - the diameter of the displeased gas plant.

Overhead (left) and roof smoke (right)

When the smoke is needed

The manufacturers of heating equipment are completing their products with traction fans due to increased heat exchanger resistance, where the gases change the direction of movement in iron pipes several times. The goal is to select maximum warmth and increase the efficiency of the boiler installation.

Nuance: The work of the smoke in the boiler of the factory configuration is coordinated with the combustion process and is controlled by the electronic unit. When installing a fan unit on the "brainless" heater, such consistency is excluded, you need to buy the automation unit or adjust the revolutions manually.

Organize the supply ventilation in the boiler room, and only then think about the purchase of smoke

We list the situation when the smoke will help improve the operation and maintenance of a solid fuel heat generator:

problems with the burden - blown by the wind, air traffic jams in the gas duct, many turns, seed diameter;
due to the characteristics of the design of the boiler smokes to the room when the door is opened;
the height of the chimney is insufficient, either the cutting of the pipe hit the zone of the winddrop behind the rod of the roof or another building;
cracks appeared in the brick tube, from where he seeps smoke.

Important moment. No fan will save position if there is no influx from the street in the boiler room. At first, the working impeller will create a small vacuum, but then the blades will be mixed in place. Supply ventilation is a prerequisite for the normal operation of any heater.

Mine heat generator V. G. Holmova is better to operate with a traction fan

Some structures of wood boilers (for example, a mine type) tend to throw away smoke through an open loading hatch. A similar pattern is observed in heat generators with a three-way heat-tube heat exchanger of increased resistance. Solving the problem - setting the traction or blowing machine controlled by the controller.

Strengthening natural traction with the help of smoke and the opposite direction. If, after heating the pipe, the natural extractor will not recovered, the unit cannot be turned off - you can be lit. Now imagine that the electricity supply ceased among the nights, the fan stopped. While the chain thermostat will cover the damper, smoke will fill the boiler room.

What is better - smoke or supercharger?

When the traction turbine is integrated into the heat generator by the manufacturer, such questions does not occur. Another thing is to add an exhaust fan to an ordinary direct burning boiler. It should be understood that in this case the smoke solves only one task - creating a vacuum in the furnace and the strengthening of thrust. Here lies a number of negative points:

Without an electronic control unit, the performance will have to be adjusted manually. Automatic maintenance of the coolant temperature is excluded.
When air is supplied through the open door of the ash chamber, the fan will make the boiler work at the maximum. Configure long-term burning mode will not be easy.
In the event of an emergency stopping of the impeller, the burning of fuel will not stop, since the gases are freely passing through the snail or the enclosure of the smoke. Air penetrates in the firebox, the probability of overheating increases.
The impeller and the inner surfaces of the unit are covered with soot that you want to delete. The speed of sticking depends on the humidity and resinness of the wood.

Comment. We do not mention the consumption of electricity fan. The consumption is relatively small and will not have a significant impact on the total cost of heating.

The disadvantages described in paragraphs 1 and 2 are eliminated by switching the smoke with the controller, the controlling turnover of the impeller and the temperature of the water shirt. Electronic blocks can be bought at a price of 50-100 y. e.

Blowing machines always work together with the controller, therefore the problems listed above are absent:

the supercharger changes performance and turns off by the command of the control unit, the coolant is heated to a given temperature;
in the process of burning, the ash bar door is tightly closed, the air is served on a separate channel;
when the electricity is disconnected, the air channel automatically overlaps the gravitational flap;
the blades of the impeller cannot be contacted with hot smoke and soot.

Reference. In pyrolysis boilers, the supervision is always applied, since the operation of this type of heaters is built on the forced injection of air.

Now compare the cost of the traction and blowing fan, without taking into account the price of the controller. Dymosos for a TT boiler up to 30 kW will cost 90 y. e., The supercharger is 60-65 y. e. The difference is due to the constructive features of the exhaust unit - the hot gases should not overheat the electric motor plus the impeller is made of metal (when superimposed - from plastic).

For the assembly flange of the unit costs a small impeller, designed to cool the electric motor

By the difficulty of installing the aggregates are about the same. Installation of the pumping snail involves drinking the opening in the door of the ashtar, smoke - disassembly or cutting the pipe. Roof hood is easier, but you have to pull a long cable.

Summary: Put the smoke only if necessary, and better - correct the errors made in the construction of the gas plant. Adjust the turbochard with electronic control at will, the system will allow you to automate and protect the combustion process.

How to make an exhaust unit

The main difficulty in assembling the smoke, with your own hands - the manufacture of a balanced impeller, the remaining parts do not represent difficulties for a homemade craftsman who owns welding. If the impact of the impeller will be varied by weight, the usual fan noise will turn into a rumble due to vibration.

In addition to the blades, you will need such elements:

the engine is electrically power up to 150 W, maximum turnover of the shaft - 1400 rp;
snail or homemade box shown in the drawing;
shaft with ventilation holes or additional cooling impeller;
studs with nuts M8 and the rest of fasteners;
power cable.

By ordinary homeowners we offer the least thorny way - to buy a factory electric motor with an impeller and a cooling impeller, weld the box and collect a completely efficient channel smoke. How to do it correctly, look at the video.

Conclusion

Creating artificial vacuum with the help of smoke disease is infrequently practiced in household boilers burning solid fuel. The technical solution leads to the rise in price and creates problems in operation. Before putting the traction unit, remember which fuel you used earlier. If you plan to burn wet wood, agricultural waste or low-quality briquettes, forget about the exhaust fan - it will have to clean weekly. Better install the supercharger with the control unit.

Fans for solid fuel and gas boilers

The fan serves as one of the main elements in the device of solid fuel and turbocharged gas heating equipment.

Its main purpose in gas turbo boilers is the forced removal of combustion products and air supply to the combustion chamber, in solid fuel - injection of air flow into the combustion chamber. Due to this, the optimal mode and the burning rate is maintained, the efficiency coefficient of the boiler is increasing.

Fan for solid fuel boiler

By parameters and functional characteristics, fans for solid fuel boilers are divided into the following types:

instruments with electro-commutable engines (EU);
fans equipped with synchronous engines;
superchargers with an asynchronous engine.

Each of the species have their advantages and disadvantages:

Electro-switched engine. This device can independently change the number of revolutions, pre-obtaining the corresponding signal from the control unit, also has a wide range of fan operation adjustment. However, the device has a number of shortcomings - it is not compatible with most temperature regulators produced by domestic producers, and besides, this technique has a high price.
Fan with synchronous motor. The device is simply in manufacturing and has a low price. But this type of fans also have a number of flaws. For example, a small adjustment range and a minimum torque during start.
Asynchronous electric motor has many advantages. First of all, it is simple and easy to use. Secondly, has a reliable design. However, there is also a disadvantage - high starting currents.

Device

Any blowing fan, regardless of which country it is produced, consists of a metal housing, and an electric motor is inside it. Also an important component of the injection fan are blades that are protected by a safety grid. The structure of the device is not complicated, but at the same time reliable.

This provides its durable case, high operating temperature and reliable electric motor manufacturer. Indoor vulnerabilities Elements and parts are protected by grid. The blowing fan has a small weight, so there is no problems with installation.

Fan for hard fuel boiler

On the Russian market you can meet fans for solid fuel boilers of the following manufacturers:

Inspection centrifugal fan (turbine) WPA of various modifications. Manufacturer - Polish company MPLUSM. This company specializes in the production of turbines for solid fuel boilers. The model uses stable demand in the Russian market, as it is characterized by high quality and good reliability.
NWS fan of various modifications. Production - Nowosolar (Poland). Purpose is the injection of air into the combustion chamber. This increases the efficiency of fuel extinguishing in the combustion chamber.

How to pick up

The performance of the boiler on hard fuel is largely determined by a properly selected fan. What does this mean?

Consider several situations:

If a fan is installed, which gives a smaller volume of the required air, then the fuel will not burn completely. As a result - the boiler power decreases and the passport temperature is not achieved.
If the fan is installed, which gives a larger amount of the required air, then the solid fuel boiler will quickly gain the temperature, and the fan will be constantly turned on and off. As a result - breakdown of the fan is inevitable, the chimney will be constantly hot, and the heat will go through it.

Output one - correctly pick up the blowing fan.

The table shows the options for installed fans on solid fuel boilers of different power.

Gas boiler fan

Gas boilers with a closed combustion chamber are equipped with a coaxial ventilation channel. Along it is distinguished by combustion products and at the same time air is served from the street.

They use a discharge fan with forced exhaust. He is responsible for the air fence and the removal of combustion products.

The power of the turbockotla fan depends on the power of the gas boiler.

The fan is placed above the combustion chamber: in the top of the boiler. It creates a discharge, as a result of which the air is sucked into the combustion chamber.

Two tubes are mounted to the fan housing: Venturi tube, Pito tube. With the help of these devices, you can measure dynamic and static pressure.

Venturi tubes are hoses and are connected to the press.

Designed to adjust the process of smoke removal and control of the functionality of the fan. Press service (air pressure switch)

The functioning of turbocharged boilers is reduced to the following:

Connecting boilers with a closed combustion chamber is made to a double-dry chimney, which is arranged on the principle: a pipe in a pipe, or to a two-pipe system - where one channel displays smoke, the other exercises a fence of air from the street.
Combustion products are discharged through the inner tube.
The outer cavity in the separate chimney of the turbocharged gas boiler is connected to the air duct, which carries out the combustion chamber oxygen.

Thus, the fan for the boiler is designed to ensure uninterrupted operation of the heating system in the house.

How to choose a fan for a hard fuel boiler

By installing an additional fan on a solid fuel or gas heater, you can optimize burning in the furnace, increasing the efficiency of the unit and at the same time reducing fuel consumption. If initially such superchargers were used in industrial installations, today they are actively used in everyday life. The fan for the boiler can be made independently, which allows you to save on the purchase of factory aggregates.

Construction and principle of operation

Depending on the type of heating boiler and the type of fuel on which it works, blasting and traction fans can be used. The first are installed at the inlet of air supply nozzle and the oxygen is injected for combustion.

Traction fans are mounted directly inside the chimney channel, create a discharge, and the boiler itself begins to pull the larger amount of air that is burned in the furnace.

Exhaust blowers used in autonomous solid fuel boilers may include the following items:

Fastener.
Heat resistant metallic impeller with curved blades.
Electric motor with a capacity of 20-50 W.
Cable power connector.
Control panel with controls.
Capillary tube and flask for temperature sensor.
Power wire with a fork.

Standard factory fans are attached to a solid metal case, which is located on the back of the boiler near the chimney pipe. The temperature sensor is in the flask and is inserted into the sleeve in the water jacket. The control panel of the supercharger is installed separately or combined with the automatic boiler automation unit.

Install the Sewber on the fan!

The principle of operation of the fan lies in the forced tap of hot gases from the heat exchanger directly into the chimney. Separate smoke models can increase or decrease the intensity of rotation of the impeller, which makes it possible to optimally control the operation of the fuel boiler.

The principle of operation of a solid fuel boiler with a installed fan looks like this:

Properly adjusted fan allows not only to improve the characteristics of the boiler, but also completely eliminates the enclosure of the indoor. Thus, the full safety of the equipment and comfort of living in a private house is ensured. Homeowner will only need to properly configure the work of the impeller, since with minimal revs, the combustion intensity decreases, and with increasing the speed of rotation of the smoke, part of the thermal energy will go into the pipe.

Varieties of traction fans

Today, you can find various modifications of traction fans intended for wood fires, solid fuel and gas heating boilers. Correctly selecting one or another fan type, it will be possible to ensure a significant increase in the efficiency of heat installations.

The following types of chymososov received the greatest distribution:

Roof fireplace and oven.
Overhead.
Centrifugal channel.
Boiler.

Overhead smokers intended for household heating boilers have a semicircular site and screed locks. This fan is mounted for a hard fuel boiler to a vertical section of a lavety chimney. Overhead smokers are characterized by the efficiency of work, have a simple and reliable design, but it is difficult to adjust such equipment correctly.

Channel fans for solid fuel boilers have their own body with two mounting nozzles and flanges. The unit is installed horizontally or vertically into the gap of the chimney pipe. The principle of operation of such a fan is similar to a boiler hood. The dynamos of the channel type was obtained the greatest distribution, which is explained by its functionality, ease of operation and the possibility of fine adjusting the frequency of rotation of the impeller. All operation of the channel fan can be fully controlled by automatic.

Fan on the boiler with 30 firebox

Electric hoods for the stoves and fireplaces are planted on the chimney headband, fixing the spacer bolts. The power cable is carried out along the pipe and connects directly to the electrical tailor or the RCD.

When choosing a type and power of the fan, it is necessary to proceed from three main criteria:

Mounting type on the ledge, pipe or inside the boiler.
Electric motors are chosen depending on the capacity of the boiler.
For overhead models, it is necessary to take into account the diameter of the displeased gas.

The basis of the fan for the heating boiler will be the electric motor that is responsible for the operation of this equipment. To date, three main types of electric motors are used:

Asynchronous electric motors.
Synchronous motors.
Electro-switched engine.

It is most often used precisely the last option, as it allows you to quickly change the number of irregular revolutions and thereby regulate the fan operation. However, in the presence of such a drive, certain difficulties appear with the choice of temperature regulators. Also, the disadvantage of fans with the electro-commutable engine is their high cost.

Fans with synchronous motors are characterized by simplicity of design and have an affordable cost. The disadvantages of this type of equipment include limited adjustment capabilities and low torque when running the motor.

Asynchronous electric motor has numerous advantages. It is convenient and easy to use, the reliability of the design is distinguished. The minuses of the drive of this type include high starting currents. Accordingly, it is necessary to properly organize the power part, which will allow to run such a demanding equipment to work.

Causes for installing a supercharger and cost

The use of a fan that injected oxygen into the furnace and selects their heat in products, it allows you to significantly increase the efficiency of the boiler installation. Top modifications of gas and solid fuel boilers are originally equipped with such smokers, the work of which is fully consistent with the heating installation. But most factory models of heaters and homemade installations do not have fans, which slightly reduces the efficiency of the equipment.

Installing the fan on the gas and solid fuel boiler will be necessary in the following cases:

Install the fan on the boiler, without coordinating the work of the heater and the supercharger, is not recommended. In the latter case, there may be a significant deterioration in the performance of the boiler, problems with extracting firewood may appear, and after complete combustion of fuel to the room from the furnace can enter the carbon monoxide.

What boiler to choose? Condensation or convection?

You should not consider fans for boilers as the only possibility of solving problems with a burden. With such faults, the chimney should be repaired, maintain the boiler service and adjust the height of the pipe above the roof. Only such an integrated approach will increase the efficiency of the boiler and make it work completely safe.

The cost of fans for boilers can vary significantly. Depending on the specific model and its type, the smoke will cost the buyer at 3-6 thousand rubles. Automation, taking into account its capabilities and the functional, will cost 3-5 thousand rubles. It is not worth saving on the fan and the control unit, since poor-quality equipment will not be able to ensure the necessary efficiency of the functioning of the heater, and the superchargers will be far from the most reliable.

Independent manufacture of exhaust aggregate

Make your own hands the fan for a solid fuel boiler will not be a special difficulty. It will only be necessary to balance the impeller whose blades should have the same weight and shape.

For the manufacture of homemade smoke, the following will be required:

Homemade metal box or snail.
Electric motor with a power of 150 W and a shaft with 1400 turns per minute.
Studs with nuts and other fasteners.
Valley with ventilation holes for cooling impeller.
Power cable.
Control block.

The easiest way to perform a smoke for the boiler, buying a factory electric motor having a impeller and a cooled impeller. All that will need to be done is to cook a metal box, place an electric motor inside it, impeller and connect the supercharger to the heating boiler.

If it is planned to independently manufacture an impeller, then it should be done strictly according to the available drawings. The blades are cut out of the metal sheet, after which they slightly grab them with welding and balanced shaft. Made with your own hands, the impeller is installed on the electric motor and check the quality of rotation. In a properly performed, the discharge must be completely absent, not only the worsening quality of air supply, but also leading to serious breakdowns of the smoke system and the entire solid fuel boiler.

The automation used can differ significantly depending on the solid fuel boiler functional. The simplest options have a temperature sensor and a dimmer, which reduces or increases the number of revolutions depending on the heating of the coolant. Also on sale you can find automatic control units with extended logic that are fully integrated into the automation of the boiler and allow you to maximize the fan effectively depending on the parameters of the heater.

Fan of solid fuel boiler

Installation of an additional smoke to a solid fuel boiler will significantly improve the performance of its efficiency and fuel efficiency. It is only necessary to choose the proper supercharger, which by power must correspond to the parameters of the heating equipment. It is also possible to manufacture a fan with your own hands to reduce the cost of heating a private house.

Fan for boiler with your own hands - Installation of equipment!

The fan for the boiler performs the function pondered during the ignition of the unit. If you turn on the fan to the maximum power, under the influence of air flow will be ensured by an increased influx of air into the combustion chamber, which will contribute to an increase in the efficiency of the entire process.

Fan for the boiler do it yourself

After the required temperature is reached, the automatic controller to which the fan is mandatory, will turn into the minimum activity mode or completely turns off the unit and the combustion will gradually subsides.

Gas gas outdoor with fan

Upon reaching a temperature of some minimum mark (usually 5 degrees below the desired temperature set by the user on the control panel of the automatic regulator), the controller will turn on the fan again, and so the process will be repeated during the entire heating cycle.

Why install the fan on the boiler?

Installing the fan on the boiler is performed to create forced thrust. Due to the modernization of the equipment in the fuel combustion chamber, the required amount of air will be continuously supplied.

In practice, it was repeatedly proved that for the most efficient operation of the boiler in the combustion chamber, more than air should be supplied than the manufacturer in the concomitant technical documentation. Without a fan, fuel will not fully mix with all oxygen. As a result, a certain part of the air will not burn, and simply blows out of the heating unit along with the smoke.

Fan on the Gas Copper Ariston

Thus, when calculating the required fan power, you need to focus on the maximum efficiency specified by the boiler manufacturer. If the power of the additional equipment is lower than the desired value, the modernization is simply not given any useful effect.

In conditions of insufficient air, the boiler operation mode will break. The fuel will not be burned completely, the chimney will begin to clog the ash and soot intensively, which will result in frequent stops of the equipment for cleaning and related service.

In terms of incomplete combustion of fuel, the insulating materials will begin to break, and their frequent replacement will lead to a significant increase in the cost of the heating unit.

Due to the reduction of thrust, the boiler room will smoke. In view of this, the owner will need to spend additional funds for installation of artificial ventilation.

Therefore, it is better to initially allocate a relatively small amount of money on the purchase of a fan, and you can install this unit you can do it yourself. Such an addition will significantly reduce the low-speed fuel, increase the power of the heating equipment and noticeably extend the life of its operation without the need to stop for repair and maintenance.

Automation of the system of forced thrust

Fans for boilers work in a complex with modern means of automation, namely, a block of controlling the operation of a solid fuel boiler. The unit controls the combustion process of fuel in the boiler in accordance with the user installed temperature mode.

The unit controls the operation of the fan and pump circulation pump. From the control unit withdrawn:

fan connector;
jack for connecting the pump;
connector for connecting to the power grid;
digital Temperature Sensor.

The standard control unit is equipped with two displays. On the same display displays information about the operation of the fan. On another display, data on the coolant temperature in the heating system is displayed.

The displays contains the control panel. Using the control panel, the owner can adjust the fan operation and set the desired temperature in the heating system.

The principle of operation of the system is as follows:

boiler is loaded with fuel;
turns on air supply;
if necessary, the required air supply parameters are set. Similarly, the temperature of the coolant in the system is adjusted.

After the desired coolant temperature is achieved in the system, the control unit will automatically turn off the fan. Such a unit allows the owner of the boiler to significantly reduce fuel consumption and save on electricity.

Using the fan on the example of the boiler bunch

An excellent example of a heating unit with an additionally installed fan is a bunch boiler. This is a full-fledged oven for long-term combustion consisting of two main parts. In the interval between the chambers, air is circulated fan.

Fan for bubafoni

The fan is connected to the maximum simple sequence.

First step. Fix the fan on the air supply pipe into the boiler.

The second step. Connect the fan to the control unit.

Third step. Turn on the necessary devices to the power grid.

Fourth step. Set the required fan parameters and the desired heat carrier temperature in the heating system.

Directly the boiler you will enjoy in this order.

First step. Tightly load firewood into the appropriate chamber. The more denser the fuel will be laid, the more effective will be heated.

The second step. Fit fuel and install on top of a pancake with a pipe for supplying air and fixed on it with a fan.

Third step. Wait about 5 minutes until the boiler breaks up and turn on the fan.

After the heating system is reached, the temperature you specify, the control unit will automatically turn off the fan. Next, the process will occur on the scheme previously discussed.

Thus, the installation of the fan for the boiler allows you to simultaneously solve many problems associated primarily with the efficiency of heating and fuel consumption. Be sure to purchase such a device for your heating unit. It is worth the fan relatively cheap, and it will pay off as quickly as possible.

TT boiler long burning energy

Heating equipment has many classifications. One of the principal signs of separation is the type of output of combustion products. In particular, there are aggregates with direct and closed withdrawal of smoke. In the first case, Gary's natural removal is carried out through a special channel associated with the equipment by means of a nozzle, and the second option does not provide for the combustion product challenge. This feature is implemented in third-party mode by individual settings. It is usually performed by smokers and fans for boilers, which in force withdraw the same smoke, cleaning the air indoors.

Accessory equipment for heating systems

The technical organization of the boiler is implied by the use of a group of drums. Such units are designed to ensure the optimal working condition of the heating equipment with the elimination of overheating risks and the removal of combustion products, if the connection to the air duct is implied. In this case, the smokers and fans for boilers are isolated, whose functions may vary.

In practice, the use of boilers with such a snap is allocated several positive effects. The main one is the possibility of maximum burning gas mixtures. Modern models of heating installations in some versions are provided for pyrolysis systems that provide double fuel combustion with the release of larger heat. In turn, the fan for the boiler in the natural mode of operation ensures the same principle, as a result, reducing and financial costs for operating equipment.

How is the fan?

The classic design of the fans for heating equipment provides for the presence of an engine, pulling the cuff, impeller and, of course, the body that protects the filling from damage. Also in the device, mechanical parts are played, implementing the movement of the installation work parts. For example, a gas boiler fan is supplied with a whole group of bearings. Actually, malfunctions in this part are the most common and arise due to poor-quality installation. Specialists note the significance of the working wheel itself, which must have solid fixation and protection against outsiders, including from garbage.

Varieties of fans

There are two concepts of structural performance of fans of this type. These are centrifugal and traditional models with discharge effect. Two fans differ in the method of supplying air masses. The first option is considered universal and suitable for most of the second solution in modern performances more functionally. Such a fan for a solid fuel boiler is installed on the zolnik door and provides an effective forced air flow. This operation scheme allows the user to rationally use the design potential in terms of the injection of air flow, while maintaining the possibility of optimal regulation of oxygen volumes entering directly into the combustion chamber.

Main characteristics

The efficiency of driving equipment is estimated at the three main characteristics - productivity, power and pressure level. In terms of performance, it can be up to 10 m 3 / h. That is, this is the volume of air mass allocated for one hour. True, most standard models provide only 3-4 m 3 / h. This value is directly related to the installation capacity, which vary from 5 to 10 kW on average. But the quality of the function will depend on the engine speed - on average 1000 rpm.

As for pressure, there are also rather dense indicators here - at least in the middle segment. For example, a small fan for the boiler is capable of providing 50-60 dap. Another thing is that high-performance industrial systems can work in modes 200-300 dap.

How to choose a fan?

Technical parameters are the primary criterion for selecting the optimal system. Next should be referred to the functionality of the unit and structural execution. It has already been noted that the paint equipment may fail due to, at first glance, minor errors in the installation. The quality of the installation and adjustment directly depends on the reliability of the structure of the structure - from the housing to parts from the element base. Therefore, choosing a fan for the boiler, it is necessary to tightly approach the quality of assembly quality, materials used and other properties of equipment that affect mechanical resistance. In addition, it makes sense to estimate the possibility of working the unit in a bundle with automatic systems. Programmable relays with laid configuration program programs today cover not only boiler stations, but also a concomitant technical equipment. Moreover, in the case of combining two units in one system, the task of interaction between their function as a result of processing related operational parameters is simplified.

How much is the fan for the boiler?

The cost is formed in several factors, but mainly the size of the installation, the quality of the element base, the characteristics of the power plant, etc. The most affordable solutions in this segment can be purchased in 5-10 thousand rubles. Of course, we are talking about optimal products according to modern quality standards. For example, a 50-kW WPA boiler fan can be purchased for 7 thousand rubles. More productive models from the industrial segment are available for 20 thousand rubles, but in this case we are talking about aggregates, the function of which is calculated on the area of \u200b\u200babout 500-600 m 2.

Conclusion

Manufacturers of boiler equipment tend to optimize the additional functionality as possible in the basic structures. But, as practice shows, individual components are not just more efficient, but also more reliable during operation. Even the typical blowing fan wins in the built-in tape regulation mechanisms due to large amounts of service. Another thing is that auxiliary equipment can become an encumbrance of the heating complex, whenever the need to apply additional service measures. But this cannot be said about the convenience of the regulation process itself. Especially if we are talking about automated systems, the operation of which is greatly simplified.

Boilers, or heat generators working on solid fuel, need a constant influx of fresh air and effective withdrawal of smoke and combustion products. To ensure an efficient mode, the oxygen is needed in the air. The natural influx used in conventional furnaces is able to provide only the minimum air flow receipt, while the use of mechanical supervision allows us to repeatedly increase the capacity of the boiler at a temperature and, accordingly, energy. In addition, use to increase the thrust allows you to increase the operating parameters of the equipment, reduce the consequences of the structural errors.

Causes of bad thrust in chimney can be a lot. These include:

admitted design errors chimney. For example, the pipe cross section does not allow for a sufficient amount of air. Or there are a large amount of sharp bends or turns that create obstacles to the passage of combustion products.
sale clustersreducing the lumen of the pipe
non-compliance with the height of the top chimney over the ridge of the roof. This can also include the presence of a number of high buildings, significantly exceeding the height of the pipe.
strengthening wind Can change the flow direction in the pipe
closed or incorrectly installed vacan
insufficient ventilation The premises often becomes the cause of the deterioration of thrust
visor on the top of the pipeMounted too low may form air twists changing the trumpet

Most of the problems may well be solved by making adjustments to the state of chimney, cleaning, changing the construction of the structure. More difficult with weather conditions, there is no possibility to change them. But there is always the opportunity to use mechanized devices that create the necessary traction mode independently of external conditions or features of the design of the boiler or chimney.

Methods for amplifying thrust in heating devices

Main waysallowing you to increase the craving in the furnaces or boilers, consist of exclusion or reduction of the amount of interference to derive exhaust gases. It is customary to use the following methods:

purification of the inner surface chimney from soy
sealing, elimination of abnormal holes, deletion and replacement of running structural elements
use of mechanical devicesstabilizing and enhancing cravings

Tip! Sometimes I have completely simple actions. For example, several increases the thrust simple installation of the deflector (Nozzles on the top of the chimney with great than that of the main pipe, diameter). When connecting to air flows of such an obstacle, a vacuum is created that contributes to the "pulling" of exhaust gases from the chimney.

In more complex or responsible cases you have to use ventilation equipment. To change the parameters of the boilers, traction (drums) fans are used, creating an increased air flow, and smokers that create a strong chimney vacuum. Both types of devices operate on boiler room or fiber equipment, but have a rather significant difference in the design. Since the smokers are installed at the end points of the chimneys, the materials from which they are created must withstand the effects of high temperatures. At the same time, the drum fans do not require an increase in strength, as they are located in relatively safe conditions and work with a cold medium.

Many manufacturers of boilers or furnaces initially complete their equipment with a particular device. Currently preference is made to give to smokeSince they create a vacuum and greater safety when the firebox is opened. Traction fans, on the contrary, create excessive pressure, which is dangerous when opening the firebox - the flame, sparks, in the room there are large quantities of smoke. Therefore, when choosing a particular device it is necessary to take into account the specifics and the device of the boiler.To avoid mistakes and reduce the possible risk.

What gives the use of a traction fan?

The combustion mode of fuel depends on the presence of oxygen. For gas boilers, a rigidly stable mode is required, withstanding a certain air supply. Solid fuel boilers of such a restriction do not have and are able to work in turbine mode (increased supervision). When using a traction fan, air is supplied to the boiler firebox under a certain pressure, which is formed by increased pressure. As a result, the combustion mode is reinforced multiple times, combustion products are actively extruded in chimney and are derived from it under existing pressure.

Important! At the same time, the installation of the traction fan is accompanied by an increase in the consumption of electrical energy, which is some disadvantage of the method.

For air supply, both radial and axial fans can be used. If you need to increase the pressure, then, if necessary, organize filling a large amount of air . It is believed that radial fans are more reliable and resistant to work, but create a big noise. The axial is not noisy, capable of moving large volumes of air, but almost do not create pressure. If the task is put only by reducing, you can do with axial devices. If necessary, together with the supervision, create an increased pressure for the effective output of combustion products, the radial fan will be required.

Purpose and device

Blowing fans are installed at endpoints of chimneys and contribute to the conclusion of combustion products by creating a strong vacuum, pulling the smoke and other gases from the furnace system and chimney. The conditions of operation of the smoke differ in high temperature loads, contact with combustion products contributes to rapid wear, metal fatigue. The design of the smoke must comply with the level of loads and ensure efficient operation during the entire service life.

The composition of the design includes:

fan in the heat-resistant version (stainless, doped or, less often, carbon steel)
guide apparatus mounted on the suction side and organizing the correct flow direction
suction funnel connecting the guide apparatus with fan inlets
electric motor

Smoke case, regardless of the material of manufacture, covered with protective polymer coating. It increases the service life of parts, contributes to a decrease in thermal corrosion of materials. The direction of inclination of the impeller blades is used both direct and reverse. The first option is most often used on small boilers with relatively soft modes of operation, the second option is used on powerful installations with high outgoing gas temperatures.

Important! The temperature output of the combustion products may be about 200-250 ° C, to high-power boilers it can rise up to 400 ° C.

For use as a smoke not only radial, but also axial devices can be applied.. There are flowing designs that are placed at the outlet of the boiler. They are not completely arranged in the channel, but only a part of the impeller, increasing thrust. Such designs are not full exhaust fans, but as the traction enhancers they are quite effective. The best option is to install specialized apparatus centrifugal type, authorizing the maximum effect.

Correct selection of smoke must be based on accurate calculation. The performance of the device must correspond to the hem bandwidth in the nominal mode, with the possibility of increasing to peak values.

Also pay attention to the type of transmission. The use of conventional belt transmission is inappropriate, as the smokers are located in uncomfortable places for maintenance and replacing belts will be too complex.

The selection of the device must be made with the calculation of the convenience of repair and replacing the blades. In this regard, preference should be given to samples that represent easy access to the impeller, eliminating the complete dismantling of the smoke.

Useful video

Previously, traction and blowing fans were used only in industrial boiler installations. The first is set inside the chimney channel and create a vacuum, the second - the air is injected into the furnace. Gradually, the aggregates moved to the household sphere - manufacturers began to equip heaters with a closed combustion chamber by turbines. The idea was picked up her home craftsmen, because the smoke for the boiler helps to solve the problem of bad thrust in the chimney tube. Let's figure it out, whether a forced hood is always necessary.

Construction and principle of operation

The exhaust smoke for the factory boiler includes the following elements (the device is shown in the scheme, the positions coincide with items):

Metal heat-resistant impeller with blades, bent under 90 ° relative to the impeller.
Fastener.
Electric motor with low performance (20 ... 50 W).
Power cable connector.
The console with controls and controls.
The flask and the capillary tube of the temperature sensor connected to the emergency thermostat.
Network wire with a fork.

Note. As an example, the Kalvis DM-01 Boiler Firms is taken. The design of other types of fans is distinguished by the body shape - snail, box, hemispherical landing site. Set of details similar.

The principle of operation of the smoke is the forced tap of high-temperature gases from the heat-tube heat exchanger of the boiler in the chimney. The algorithm looks like this:

The fuel is filled with firewood, ignition is produced.
The loading door locks down, confused - opens. The fan turns on the key on the console, then the performance is configured.
When the heating installation and chimney warms up, the impeller speed manually decreases to a minimum. If the heat generator is enough natural traction, the smoke is recommended to disable.
When the heat carrier is heated to a critical temperature of 100 ° C and more on the sensor command, an alarm thermostat is triggered, which turns off the fan automatically.

Scheme of work of boiler smoke

Reference. On TT-boilers, equipped with automatic, do not need to open the door of the roller. The thermostat by chain will open the air supply damper to the desired angle.

Almost can be removing with turnover - the lion's share of warmth will go into the pipe. Before opening the door and reloading the speed of rotation is better to increase to the maximum.

Varieties of traction fans

For and wood fireplaces, several types of smokers are sold:

boiler (design considered above);
centrifugal channel;
overhead;
fireplace / oven (it is roof).

Various nozzles that improve natural cravings are not included in the smoke, are deflectors, round rotary elements and rotating flugers. The effectiveness of these caps depends on the wind speed, which changes together with the weather.

Dimensions of channel smoke, some models are equipped with temperature sensors

The channel fan is distinguished by its own body with two connecting flanges or nozzles. The unit is installed vertically or horizontally into the gap of the chimney channel. The device and principle of action is similar to the work of the boiler smoke.

The overhead smoke for the household boiler is equipped with a semicircular platform and screed locks. Installation is made on the vertical section of the chimney (displeased):

On the paper template in the pipe is cut out the opening.
The impeller of the traction machine is inserted into the hole, the platform with the electric motor presses to the surface by the locks.
The compound is condensed with asbestos cord, glued to the inside of the smoke mounting site.

Note. The invoicing element is selected by the diameter of the gas duct. The installation process is shown on video.

Electrical hoods for sitting on a brick chimney ledge and fasten with spacer bolts. The power cable is paved along the pipe and is entered into the room next to the home furnace.

To choose a traction machine, you need to navigate 3 criteria:

the power of the heat generator, the smoke models are calculated on the capacity of boilers up to 20, 30, 50 and 100 kW;
installation point - on the bolet itself, pipe or glove;
for false models - the diameter of the displeased gas plant.

When the smoke is needed

Organize the supply ventilation in the boiler room, and even then think about the installation of the smoke

We list the situation when the smoke will help improve the operation and maintenance of a solid fuel heat generator:

problems with the burden - blown by the wind, air traffic jams in the gas duct, many turns, seed diameter;
due to the characteristics of the design of the boiler smokes to the room when the door is opened;
the height of the chimney is insufficient, either the cutting of the pipe hit the zone of the winddrop behind the rod of the roof or another building;
cracks appeared in the brick tube, from where he seeps smoke.

Important moment. No fan will save position if there is no influx from the street in the boiler room. At first, the working impeller will create a small vacuum, but then the blades will be mixed in place. - Mandatory condition for the normal operation of any heater.

Mine heat generator V. G. Holmova is better to operate with a traction fan

What is better - smoke or supercharger?

When the traction turbine is integrated into the heat generator by the manufacturer, such questions does not occur. Another thing is to add an exhaust fan to an ordinary direct burning boiler. It should be understood that in this case the smoke solves only 1 task - the creation of a vacuum in the furnace and the amplification of thrust. Here lies a number of negative points:

Without an electronic control unit, the performance will have to be adjusted manually. Automatic maintenance of the coolant temperature is excluded.
When air is supplied through the open door of the ash chamber, the fan will make the boiler work at the maximum. Configure long-term burning mode will not be easy.
In the event of an emergency stopping of the impeller, the burning of fuel will not stop, since the gases are freely passing through the snail or the enclosure of the smoke. Air penetrates in the firebox, the probability of overheating increases.
The impeller and the inner surfaces of the unit are covered with soot that you want to delete. The speed of sticking depends on the humidity and resinness of the wood.

Comment. We do not mention the consumption of electricity fan. The consumption is relatively small and will not have a significant impact on the total cost of heating.

The blowing fan with the automation unit performs the same functions as the smoke

Blowing machines always work together with the controller, therefore the problems listed above are absent:

the supercharger changes performance and turns off by the command of the control unit, the coolant is heated to a given temperature;
in the process of burning, the ash bar door is tightly closed, the air is served on a separate channel;
when the electricity is disconnected, the air channel automatically overlaps the gravitational flap;
the blades of the impeller cannot be contacted with hot smoke and soot.

Reference. In pyrolysis boilers, the supervision is always applied, since the operation of this type of heaters is built on the forced injection of air.

For the assembly flange of the unit costs a small impeller, designed to cool the electric motor

Summary: Put the smoke only if necessary, and better - correct the errors made in the construction of the gas plant. Adjust the turbochard with electronic control at will, the system will allow you to automate and protect the combustion process.

How to make an exhaust unit

In addition to the blades, you will need such elements:

the engine is electrically power up to 150 W, maximum turnover of the shaft - 1400 rp;
snail or homemade box shown in the drawing;
shaft with ventilation holes or additional cooling impeller;
studs with nuts M8 and the rest of fasteners;
power cable.

Private Homeowners We offer the least thorny way - to buy a factory electric motor with an impeller and a cooling impeller, weld the box and collect a completely efficient channel smoke for a TT-boiler. How to do it correctly, look at the video.

Conclusion

Creating artificial vacuum with the help of smoke is infrequently practiced in household solid fuel boilers. The technical solution leads to the rise in price and creates problems in operation. Before you put a traction fan to chimney, remember which fuel you used earlier. If you plan to burn wet wood, agricultural waste either low-quality briquettes, forget about the smoke for the boiler, clean the impeller will have weekly. Better install the supercharger with the control unit.

What is a domain:

The domain is the site address on the Internet, a set of letters and numbers, as a phone number. Address of our site - Dra.ru, address of VKontakte - VK.com, address Yandex - Yandex.ru. Domains are registered and serviced by domain registrars. Each site on the Internet has its own domain. Your site also, only now the domain does not work and need to restore it.

To whom the domain is issued:

On an individual or on a legal entity at your request. If you are an individual entrepreneur, then from the point of view of the legal status of domains, the domain is drawn up on you as an individual. For some domain registrars, it is possible to design and on non-residents of the Russian Federation (foreign individuals and companies).

Who owns the domain:

The domain is not an object of property law (as an apartment or car), therefore he has no owner from a legal point of view. Domain - recording in the registry of the domain registrar, who has an administrator who is in essence and is the owner (manages the domain, extends, can pass the domain to another administrator). You can check who is the domain administrator through the WHOIS service from the registrar, for example, in the axelname - if in the ORG field: written by Kreobits or Creobits - it means a domain with us if Private Person means a domain from a private person (in accordance with FZ-152 on personal Data, the recorder does not have the right to specify the name in public data and therefore the "Private Person" is written for all individuals).

We create on your profile of individuals or the requisites of Jurlitsa Account (Treaty) at the accredited domain registrar and carry out the domain registration for you. Create under the site a new hosting and rebreak up the site page with text and pictures on the modern system management system MODX. As a result, we get a fully working site that looks and filled in the same way as the site that you have had before. We pass to you passwords on the domain, site editor and hosting.

What is hosting:

In order for the site to be available via the Internet, it must be placed on the Internet server (specialized computer). This service is called " hosting"(from English. hosting.). Technically - the site is a set of files, it is posted on the hosting and becomes available from any device connected to the Internet. If hosting is good, then the site is always available, it works quickly and does not break. If hosting is bad - the site will work slowly and with interruptions. We place recovered sites on the equipment in the selektel data center (Moscow), this is one of the best hosting providers in the territory of the Russian Federation.

What is MODX:

MODX is a site management system from English. CONTENT MANAGEMENT SYSTEM (CMS). It is needed that the site worked, conducting an analogy - as Windows is a system for managing a computer, and Android is for a smartphone and tablet and MODX - this is the same, only for the site. But unlike Windows and Android, for sites there are hundreds of different intended and complexity of sites management systems, the most common of which 1C-Bitrix, UMI.cms, WordPress, Joomla and MODX. The main task of MODX, like any other CMS - ensure the work of the site and convenient tools for editing it with a programmer and editor (for example, your organization manager). CMS are paid and free, MODX is free, all management in Russian.
