METHOD FOR OPERATION OF THERMAL POWER STATION Russian patent published in 2021 - IPC F01K13/00 

FIELD: thermal power engineering.

SUBSTANCE: invention relates to thermal power engineering, it can be used in thermal power stations. A method of operation of a thermal power station is proposed, characterized by the fact that the condensing and backpressure steam turbine units are operated. Steam is generated in steam boilers, superheated in the main steam super-heaters and fed to the condensing and backpressure turbines. After partial expansion in the high-pressure cylinder of the condensing turbine, the steam is reheated in the intermediate super-heater. Then it is fed back to the high-pressure cylinder of the condensing turbine. The steam spent in the high-pressure cylinder of the condensing turbine is fed to the low-pressure cylinder of the condensing turbine. The steam spent in the low-pressure cylinder is directed to the condenser. The steam from the turbine selections is diverted to regenerative heaters, in which the main condensate after the condenser and the feed water after the deaerators are heated. The feed water of the condensing steam turbine unit in the second high-pressure heater is heated by steam from the exhaust of the backpressure turbine. Deaeration in the backpressure steam turbine unit is performed by steam from the last selection of the high-pressure cylinder of the condensing steam turbine unit. The condensate returned to the backpressure steam turbine unit is heated in the low-pressure heaters of the condensing steam turbine unit.

EFFECT: invention is aimed at improving the operation of a thermal power station, which allows increasing its electrical efficiency.
