The invention relates to a power system and can be used in the boiler building, thermal power plants running on gas turbine cycle, gas-turbine engines.

Known device that implements the method of heating, the conclusion is s heating ("Inventions", VNIIPO, Moscow, N 20 (II h), 1997, pp. 329, application N 93030908/06, MKI F 24 D 11/02).

In this way it is compressing air in the compressor. The drive of the compressor of the heat pump uses hydraulic turbine, a turbine shaft connected by means of bevel and planetary gears with the shaft of the heat pump.

The main disadvantage of the use of compressors for compressing air in their intensity, machine drive, as well as the complexity and metal devices in General.

Known boiler type ILC-4G (catalog-Handbook K8-70, sheet No. 3, NIIINFORMTYAZHMASH, Moscow, UDC 697.326.62-52 prototype) containing block burner for burning fuel, a closed loop circulation of the liquid coolant with pump, supply and return piping, regenerative heat exchanger heat transfer in the circuit of the consumer with radiators, a pressurizer, in which the pressurization of the air duct on the fan site - furnace is carried out using a centrifugal fan.

From furnace flue gases pass into a rotating frame, where through the smoke pipes go into the smoke box. Gas tract - furnace and all gastate thrust, the generated exhaust (flue) pipe.

Such heating installations (boilers) have the following main disadvantages:

- blowing the compressor does not provide high pressurization, and therefore, high restorepagesize gas tract, which reduces the heat output of the boiler;

in the heating installation this boiler is an exhaust pipe (increasing size), providing a natural circulation air-gas environment, through which a forced reset of the heat into the surrounding space.

The invention aims to remedy these disadvantages, increase reliability and efficiency, reduced weight and size characteristics of the heating units.

This object is achieved in that in the heating installation comprising a closed loop circulation of the coolant, on the site of a feed line from the pump to the boiler, installed in series water-air ejector and the compensator, made in the form of separator-compensator, the air cavity of the ejector is connected with the atmosphere, the air cavity of the separator - compensator are connected through valves to block the burner of the boiler, and water panicheskogo solutions to the prototype and other known analogs in this area has shown this set of features in the proposed combination is new, used for the first time and have not previously used.

Thus, the proposed solution meets the criteria of the invention of "novelty."

A comparative analysis of the proposed technical solutions to the prototype and other known technical solutions in this area has shown that this solution is superior to known solutions due to the fact that in naduvath the paths of the boiler maximum use of the heat transfer ability of the gas coolant because of a lack of traditional limiter - energy-intensive compressor not clear from the achieved level of art, it is not obvious to a person skilled in the field of industry and exceeds the achieved level of technology.

Thus, the proposed solution meets the criteria of the invention "inventive step".

The supply of natural gas to the burner unit 2 and the ignition device 3 is in the pipeline, equipped with a shutoff and regulating valves: shutoff valve 16, valve 17, 18 with the actuator, throttle 19 and the throttle plate 20.

Operation of the heating system, with pre-filled water tract begins with the start of the motor of the pump 6 and, with a period of time, by opening a shut-off valve 14. Begins the process of movement of a mass of fluid (water), which are mixed in the air ejector 7 with atmospheric air.

Getting into the separator-compensator 8, water-air mixture due to sudden expansion and deep dispersion, is divided into phases. Water flows through the water-heating element 22 of the boiler 1 to the recuperative heat exchanger 9 and the return line 24 to the input of the pump 6. The valve 10 is used to regulate the flow of water in supply 23 and 24 reverse pipelines, as well as when charging path from an external reservoir.

The air component of the water-air mixture, with the opening of the valve 11, under specified pressure rushes to block the burner 2, the ignition device 3 and later in the boiler furnace 1 through mode produoe pipe 5.

After purging air tract open up sequence, the valve 16 and valve 18. Natural gas gets into the ignition device 3, where the gas-air mixture is ignited using an ignition unit 4. A constant ratio of gas and air in the mixture is provided by orifice plates 13, 20 and regulator air flow 15.

The main gas flow at the opening of the valve 18 is supplied through block 2 burner in the boiler furnace 1, where it burns down.

Control mode independent boiler for heating power is carried out in the ratio, which ensures complete combustion of fuel.

The products of combustion, giving the major part of its heat to the water-heating element 22 located in the boiler furnace 1, cooled, and released into the atmosphere.

Circulating in a closed water circuit, the coolant through the heat exchanger 9 transmits heat in the circuit of the consumer 25 heating appliances and their circulation pump.

The use of the presented solution will allow you to:

to provide 5-10 times higher boost and consequently 2.2-3.2 times higher restorepagesize gas path of the boiler;

- increase n the efficiency of the heat of the combustion products to 97% (no exhaust);

- cut 2-3 times the volume of the gas path, size and metal of the boiler or while maintaining the dimensions of the boiler to increase accordingly 2-3 times the heat output of the heating installation.
