METHOD OF MAKE-UP FEED WATER HEATING IN THERMAL POWER PLANT Russian patent published in 2016 - IPC F01K17/02 

FIELD: power engineering.

SUBSTANCE: invention relates to heat engineering and can be used at thermal power plants. Method involves formation of steam in boiler and steam feeding into cogeneration turbine from which extracted steam is directed to regenerative and network heaters, and waste steam turbine is fed into the turbine condenser. Main turbine condensate is supplied from the condenser through the ejector coolers, sealing coolers and low pressure heaters to feed water deaerator, and water and steam losses are compensated by make-up feed water deaerated in the deaerator for make-up feed water. Steam condensate as heating agent is supplied from the ejectors cooler and sealing cooler into the deaerator for make-up feed water.

EFFECT: using the invention allows improving reliability and economy of thermal power station owing to reducing heat losses in the condenser of the turbine.
