METHOD OF OPERATION OF THERMAL POWER STATION Russian patent published in 2007 - IPC F01K17/02 

Abstract RU 2309262 C2

FIELD: heat power engineering; thermal power stations.

SUBSTANCE: according to proposed method of operation of thermal power station exhaust 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 successively cooled in convection steam super heater, water economizer, high-pressure gas-water heater and low-pressure gas-water heater. Superheated steam after steam boiler ste4am super heater is directed to extractions of which steam is directed to heat system water in lower and upper system heaters. Regenerative heating of main condensate of steam turbine plant is provided successively in for regenerative low-pressure heaters connected, respectively, to seventh, sixth, fifth and fourth extractions in direction of steam flow in steam turbine passage. Low-pressure gas-water heater is cooled by deaerated water circulating in closed circuit with water-to-water heat exchanger in which additional feed water is heated after vacuum deaerator.

EFFECT: increased economy of thermal power station owing to creating conditions for additional generation of electric energy at heat consumption of steam turbine and more complete use of excess heat of exhaust gases of gas turbine plant.
