METHOD OF OPERATING THERMAL ELECTRICAL POWER STATION Russian patent published in 2008 - IPC F01K13/00 

FIELD: electrical engineering.

SUBSTANCE: invention to power production and can be used at the thermal electrical power stations. Steam generated in the boiler is fed into the steam turbine. Admixtures accumulated in the said boiler are discharged there from along with bleed water used as a heating medium in the water-to-water heat exchanger. Feedwater supplied into the boiler is heated by the turbine bleed steam in the regenerative heat exchangers. A heating medium of the heat exchanger connected to bleed water pipeline represents a condensate of the high-pressure regenerative heat exchanger, the final one along the feedwater flow. The said condensate heated in the water-to-water heat exchanger is pumped over into the feedwater line ahead of the boiler.

EFFECT: higher efficiency.
