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 with a drum and a firebox contains a burner with fuel and air supply pipes connected to the boiler furnace, the flue gas duct, connected to the boiler furnace, and the exhaust fan connected thereto, a purge water pipeline is connected to the fuel supply pipeline in front of the boiler burner, and in the flue gas duct between the boiler furnace and the exhauster, a condenser of water vapor contained in the exhaust gases is included, connected via a cooling medium to the source water pipeline before the deaerator and a condensate line connected to the deaerator.

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.
