OPERATING METHOD OF THERMAL POWER STATION Russian patent published in 2011 - IPC F01K17/02 

FIELD: power industry.

SUBSTANCE: operating method of thermal power station, as per which live steam is produced in the boiler and supplied to the turbine; turbine exhaust steam is condensed in condenser; main turbine condensate is heated in low pressure heaters with steam of regenerative bleeding off points; delivery water is heated in network heaters with steam of heating bleeding off points of turbine; delivery water leaks in heating network are made up with make-up water which is prepared in water treatment plant of heating network and in deaerator; for that purpose the primary water is supplied to water treatment plant of heating network; the main turbine condensate after low pressure heater which is the first in condensate flow and prior to supply to low pressure heater which is the second in condensate direction is cooled in surface cooler with primary water supplied to water treatment plant of heating network.

EFFECT: invention allows improving reliability and economy of thermal power station owing to additional generation of electric power on heat consumption at provision of technologically required heating of primary water for preparation of make-up water before water treatment plant and vacuum make-up water deaerator of heating network.
