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, supplied to the turbine; exhaust steam of turbine is condensed in condenser; main turbine condensate is heated in low pressure heaters with steam of regenerative bleeding offs; delivery water is heated in system water heaters with steam of heating bleeding offs of turbine; delivery water leaks in heating network is made up with make-up water which is prepared in vacuum make-up water deaerator of heating network, for which purpose the primary water is supplied to it; make-up water storage tank is connected to vacuum make-up deaerator of heating network; the main turbine condensate after low pressure heater which is the second in condensate flow and prior to supply to low pressure heater which is the third in condensate direction is cooled in surface cooler with primary water prior to its supply to vacuum make-up deaerator 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 prior to its supply to vacuum make-up water deaerator of heating network.
