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 convection steam superheater, water economizer, high-pressure gas-water heater and low-pressure gas-water heater are installed, and superheated steam after steam boiler steam superheater is directed into extraction steam turbine plant from controlled steam extractions of which steam is directed to heat heating system water in lower and upper system heaters, feed water deaerated in higher pressure deaerator is directed through feed pump into high-pressure gas-water heater of steam boiler. Additional feed water after atmospheric deaerator is heated in water-to-water heater connected by heating medium line to deaerated water pipeline after higher pressure deaerator after which cooled deaerated water is directed for heating, successively, in steam boiler high-pressure gas-water heater and group of heaters of high-pressure regeneration system of steam turbine plant.

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.
