The invention relates to heat engineering and can be used in gasified boilers with contact preheaters.

The purpose of the invention is to increase the efficiency by using more of the heat of the combustion products and increasing the amount of condensate produced.

The drawing shows the printable scheme of the proposed installation.

The boiler plant contains a water heat exchanger 1, connected by a heated path 2 to 1} 1 stroke of the 1st air heater 3, and a heating path 4 to contact economizer 5 installed together with a surface heater 6 in path 7 of the flue gases of the boiler 8, and contact heater 9 The contact economizer 5 is supplied with a forehead of 1.1K gas stage 10, the contact heater 9 is connected by input 1 I via gases to the flue gas path 7 of the boiler 8 before the surface heater 6, output 12 to the contact economizer 5 through the upstream stage 10, but to the water - to the surface heater 6 with the formation of a circulating circuit) a 13. Kote; 1- to the installation also contains a blower wemtile torus 14, a smoke exhauster 15, a deaerator 16 HO.I- threads of the system 17 with heat consumer 18 and a hot water system 19 with heater 20 connected to contact economizer 5. Deaerator 16 is connected to co-hectare economizer 5 via decarbo1 H1 for 1 op 21 and condensate collection tank 22, circulation circuit 13 to supply line 23, and pin heater 9 to lipni 24 purge.

During the operation of the boiler plant D1z1m (), the fresh gases from the cat; | and 1 flow into the preheater 6, where the circulating circuit 13 is heated by water. Part of the flue gases and the heated luxia enter the contact 1P51Y heater 9, from where the fume gases with the fresh water content are fed through the first-stage 10 to the contact ehumizer. lloc. ie upstream stage 10 fails

Also, a part of the gas flow cooled in the top of the heater 6. In the contact economizer 5, the flue gases are cooled and the water and water vapor is condensed. Excess condensate through calciner 21 and collection tank 22 is directed to deaerator 16 to feed heating system 17. The heat from the con-TaKTiioro economizer 5 through the water heat exchanger 1 is transferred in the contact air heater 3 to the blast air, which is partially humidified, and through the heater 20 to the hot water system 19. The compensation of the water evaporated in the contact preheater 9 is supplied by the flow circuit of the circulation circuit 13 but line 23. And the purge flow is through line 24.

The boiler plant, by saturating the D1 of the pure gas with water and vapor, allows, without curtailing the combustion mode in the boiler 8, to obtain a sufficient amount of condensate to feed the heating system without using a chemical water purification system.
