Air heating and ventilation of greenhouses, poultry farms, repair shops, garages and other industrial and service premises became possible thanks to the use of steam or water caloric plants receiving coolant from boiler houses, and heat generators, which in the absence of coolant centralized heat supply serve as air heating sources. Heat generators are also used for drying various crops, drying grass by the method of active ventilation and in construction (for example, on internal finishing works) .
Stationary heat generators. The highest use was obtained by heat generators TG-75, TG-150, TG-1, TG-2.5.
TG-75 and TG-150 heat generators, equipped with water heaters, are particularly appropriate where, along with heating, hot water is needed.
TG-1 and TG-2.5 heat generators are fully automated, compact and easy, differ from each other only thermal power and dimensions.


Figure 17 shows the design of the TG-1 heat generator. The cylindrical body 4 is welded from thin-sheet steel. Inside the case there is a heat exchanger 3 with a protective cover 5, the main fan 6 with an electric motor and chimney 1.
The heat exchanger consists of a combustion chamber and a ribbed radiator with inserts that slow down the traction. The casing serves as a screen that protects the housing of the heat generator from overheating.
Outside to the housing is attached nozzle 7 for burning liquid fuel, fuel sump 8, control cabinet 9 and sensors 2 of the control system of the heat generator. The injectory assembly includes a centrifugal fan that feeds the air into the combustion zone, and the fuel pump (are given from the total electric motor).
The automatic control system of heat generators TG-1 and TG-2.5 allows you to do without constant observation by the service personnel. In case of failures in automation or but other reasons, heat generators are transferred to manual control with continuous control over their work.

In the "Heating Automatic" mode, the control system provides: automatic inclusion of the heat generator, when the air temperature in the heated room will be lower than the estimated; Automatic shutdown of the heat generator, as soon as the air temperature in the room reaches the specified (disconnection can occur for other reasons: does not ignite the torch when the heat generator is turned on or it is suddenly going out during the operation of the unit, the failure of some elements of the circuit - photoresistance, relay, etc., triggering ); repeated short-term ignition feed if the torch accidentally went out during normal operation of the unit; protection of equipment and apparatuses of the scheme from possible short circuits, and the motor of the main fan - also from overload; Signaling about normal operation and emergency disconnections of the heat generator.
The main technical indicators of stationary heat generators are shown in Table 10.
A special group of heat generators is a gas surface air heaters operating on natural gas developed by the Institute of VNIipcrogas (Table 11).

Models K-50 and K-100 - horizontal type, GPV-350 and K-500 - vertical in Figure 18 shows a scheme of the gas air heater K-100.
In the air heaters of the K-50 and K-100 one by one fan, driven by a power of 5.5 kW. In the fan compartment of a more powerful heat generator K-500, three fans are installed: two of them serve air to heat, one - in the burner. Total power of electric motors of 30 kW fans. The air heater of the GPV-350 is not equipped with a fan; The latter is selected at the installation site, based on the total resistance of the unit and the air duct system
The heat exchange radiation surfaces of gas air heaters are made of heat-resistant steel, all other elements are made of carbon.
Heat generators are fed into the heated air of the focused jet. If it is necessary to distribute the coolant on the air duct system, then it is necessary to select such fans with the corresponding electric drive in the known resistances of the air heater of the air heater and air ducts, which will ensure the aggregates of the nominal air consumption.

Device and operation of the heat generator TG-2.5

The heat generator TG - 2.5 (Figure 14) is an installation for heating air products of fuel combustion and surface heat exchanger 3.

1 - a high-guide with an electric motor and a casing; 2 - chimney; 3 - heat exchanger; 4- Corps; 5 - automatic system sensor; 6 - nozzle; 7-fuel sump; 8 - ignition transformer; 9- Management Station.

The main axial fan 1 is designed to supply cold air to the heat generator for heating it. The fan is activated from the electric motor with a power of kW. The fan performance is adjusted by changing the angle of rotation of the blades.

The heat exchanger is made of heat meters, stainless steel. To increase the heating surface, it has 16 ribs inside which the inserts of two types that serve as traction retarders are placed. Combustion products pass between inserts and ribs, give them their heat and go into chimney 2 . The heat exchanger has a neck for installing a nozzle with a mechanical fuel sprayer 6 and a hatch pipe.

The nozzle is designed for burning liquid fuel. Consists of a housing, an electric motor, on the shaft of which the wheel of the blowing wheel is notaled centrifugal fan, fuel pump with a drive from this electric motor through an elastic coupling. Power of the electric motor - 0.6 kW, 2800 rpm. The pump serves fuel under the pressure of 0.98-1.37 MPa (10-14kgs / cm 2) through the magnetic valve along the central fuel line into the sprayer.

The flow of fuel passing through the sprayer receives a rotational-vortex movement and is sent to the combustion chamber in the form of a cone. The pressure of the fuel pump is adjusted using the adjusting screw and the control pressure gauge.

Before entering the combustion chamber with airflow, a swirl is also reported to a rotational-vortex movement, but opposite with sprayed fuel directions.

The amount of air supplied by air damper built into the nozzle body.

Spray fuel consists of nozzles, swirl, nuts

and filter. Rotationally vortex movement fuel gets in grooves internal surface nozzles.

The injector ignition system includes a ignition transformer-1020 K, electrodes fixed in insulators, and high-voltage wires with tips. Electrodes are made of steel X25T and are located necessarily above the sprayer in strict accordance with the installation scheme. With incorrect installation of electrodes, fuel ignition will not happen, and the ignition transformer may fail. Spray fuel flammifies exclusively using an intersecting spark between the electrodes, when applying for them high voltage from the transformer.

Control over the torch is carried out by two photose presticks in the block inserted into the hole of the nozzle housing.

A box with a clermin is installed on the nozzle, which is connected: the nozzle electric motor, the ignition transformer (primary winding), the solenoid valve and the photoresistance unit.

The solenoid valve with an anchor coil disconnected under the action of spring and pressure ensures reliable overlap of the exhaust channel of the distributor. When the coil is turned on, the anchor opens the exhaust channel and fuel comes through the central fuel line into the combustion chamber. For dense locking, the exhaust channel anchor is equipped with a rubber gasket made from the scrap-resistant rubber of the brand and a thickness of 4 mm.

Plant developed I. serially from 197 bg, a new heat generator TG-2.5 A. is produced in this unit. Automation and fuel equipment are unified with a TG-2.5 heat generator. However, the new heat generator has a number of advantages: the efficiency is increased by 12%; Specific metal is reduced by 5.2%; Improved, the design of the burner and the regulator (guide apparatus) of air supply; An audible alarm is introduced; An explosive safety valve and a manual pump BKF - 2M, etc.

Heat generator control systems

Depending on the time of year, the heat generator can be used as a heater or fan. The control system of the heat generator is automatic-and survived to work without constant observation by the service personnel in the "Heating automatic" mode. In addition, the control system provides for the necessary manual control of the heat generator in the necessary cases.

The control system in the "Heating automatic" mode provides for the following operations:

but) Automatic inclusion of the heat generator, if the air temperature in the heated room is lower than specified. The inclusion occurs in the following sequence:


  • The nozzle motor is activated for purging the combustion chamber;

  • fuel and ignition are fed;

  • ignition is turned off (after fuel ignition); fan electric motor;
b) automatic shutdown of the heat generator;

  • If the air temperature in the heated room reached a given value;

  • If the torch did not stop when the heat generator is turned on;

  • when the torch is resetting during the operation of the heat generator;

  • When overheating the heat generator over the permissible temperature;

  • If you refuse some elements of the scheme (photos prestings, relays, etc.) and triggered protection. Disconnection occurs in the following order: at the same time the fuel supply is stopped and the nozzle electric motor is turned off;

  • The fan electric motor is turned off (after cooling the combustion chamber);
in) repeated short-term ignition feed when the torch is randomly populating in the normal mode of the heat generator);

d) The signaling of the normal operation of the heat generator to emergency disabilities.

Heat generators are effective air heating equipment. The heat generator has proven itself in heating systems used for heating the premises of large sizes. The output air pressure generated by the fan allows to operate heat generators in extended ventilation networks.

Heat generators belong to indirect heating air heaters and consist of the following main assembly units: fuel block, block burner with control panel, control cabinet.

The principle of operation of heat generators is that the fuel enters the burner, which is mixed with air supplied to burning, and burns in the combustion chamber. The resulting combustion products pass through the heat generator heat exchanger, giving heat through the heat exchanger walls heated air, and removed by chimney pipe It is excluded outside to get them into the heated room or grain. Thus, there is no direct contact between the combustion products and the heated air. Two-stage regulation "Big" and "Small Fire" provides economical use of fuel and improving supply air parameters.
