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

FIELD: heat power engineering; thermal power stations.

SUBSTANCE: according to proposed method, exhaust gases of gas turbine plant - oxidizer for combustion of fuel, and directed to burners of steam boiler in downtake gas duct of which combustion products are successively cooled in convection super heater, water economizer, high-pressure gas-water heater and low-pressure gas-water heater. Superheated steam after steam super heater of steam boiler is directed to extraction steam turbine plant from regulated heating extractions of which steam is directed for heating system in lower and upper system heater. Regenerative heating of main condensate of steam turbine plant is provided successively in four regenerative low-pressure heaters connected, respectively, to seventh, sixth, fifth and fourth steam turbine 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 desalted water is heated before atmospheric 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.
