METHOD OF OPERATION OF THERMAL POWER STATION Russian patent published in 2008 - IPC F01K17/02 

FIELD: heat power engineering.

SUBSTANCE: according to proposed method of operation of thermal power station, waste gases of gas-turbine plant-oxidizer for combustion of fuel are directed to burners of steam boiler in downtake gas duct of which combustion products are cooled in convection steam superheater, water economizer, high-pressure gas-water heater and low-pressure gas-water heater, superheated steam after steam boiler steam superheater is directed to extraction steam turbine plant from controlled heating extractions of which steam is directed for heating system water in lower and upper system heaters, feed water deaerated in higher pressure deaerator is heated to required temperature before delivered into water economizer of steam boiler. Additional feed water after atmosphere deaerator is heated in water-to-water heater connected by heating medium line to deaerated water pipeline after higher pressure dearator, after which cooled deaerated water is directed successively into regenerative lower pressure heater and through feed pump, into high pressure gas water heater of steam boiler.

EFFECT: increased economy of thermal power station owing to provision of conditions for additional power generation at heat consumption of steam turbine and more complete utilization of excess heat of waste gases of gas-turbine plant.
