BOILER PLANT Russian patent published in 2019 - IPC F22B33/00 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of heat power engineering and can be used in the operating on natural gas boiler plants. Boiler plant contains a burner with fuel supply pipe and an air duct connected thereto, a flue gas duct with a smoke exhauster included therein, purge water piping is connected to the duct in front of the boiler burner, and a condenser of water vapor contained in the flue gas, connected through a cooling medium to the source water pipe before the deaerator and connected to the deaerator condensate line, is connected to the flue gas duct between the boiler furnace and the exhaust fan.

EFFECT: improving the environmental safety and efficiency of the boiler plant by lowering the combustion temperature in the most heat-stressed part of the furnace and reducing the concentration of nitrogen oxides NO_x in exhaust gases, as well as more complete utilization of the heat of exhaust gases.
