THERMAL POWER STATION OPERATING PROCESS Russian patent published in 2007 - IPC F01K17/02 

FIELD: thermal engineering; thermal power stations.

SUBSTANCE: proposed operating process implies that demineralized water is heated upstream of atmospheric makeup deaerator to ensure normal operation using for the purpose stable low-potential heat source. To this end steam is taken from three first extraction points of type T extraction turbine for high-pressure regenerative heaters and from four last ones, for low-pressure regenerative heaters wherein full-flow condensate is sequentially heated downstream of turbine condenser and feedwater; delivery-water heating steam is taken from seventh and sixth extraction points of type T turbine for bottom and top delivery-water heaters, respectively; demineralized water is heated prior to its supply to atmospheric makeup deaerator in heating-medium steam-water heat exchanger using steam from fifth extraction point of type T turbine that has heating-steam extraction stages.

EFFECT: enhanced reliability and economic efficiency of thermal power station.
