FIELD: heat power engineering.
SUBSTANCE: proposed thermal power station has gas-turbine plant, steam boiler to which gas duct of oxidizer-waste gases of gas turbine is connected, and convection steam superheater, water economizer, high-pressure gas-water heater arranged in boiler downtake gas duct, extraction steam turbine plane with heating and regenerative steam extractions, condenser higher-pressure deaerator connected by deaerated feed water pipeline through feed pump with high-pressure gas-water heater of steam boiler. Water-to-water heater installed for heating additional feed water after atmospheric deaerator is connected by heating medium line to pipe for feed water deaerated in higher pressure deaerator before series-connected regenerative low-pressure heater connected to turbine extraction and high pressure gas-water of steam boiler.
EFFECT: increased economy of thermal power station.
