OPERATION OF THERMAL ELECTRIC POWER STATION Russian patent published in 2015 - IPC F01K17/02 

Abstract RU 2569993 C2

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. In compliance with the claimed process, used steam is fed from the first turbine to the condenser steam chamber and condensed at the surface of condenser tubes wherein cooling fluid circulates. The condensate is fed by the steam turbine condenser pump to recovery system. The low-potential waste heat power of waste steam is recovered with the help of cooling fluid. Note here that the steam turbine exploits the bearing oil feed system provided with the oil cooler while the thermal power station incorporates the second steam turbine condenser and bearing oil feed system with oil cooler. Besides, the second steam turbine high-potential steam heat and the second steam turbine bearing oil feed system low-potential heat are recovered. Note here that said recoveries are executed with the help of heat Rankin-cycle engine running on low-boiling working fluid cycled in closed circuit. Said heat engine exploits either air cooling condenser, or air and water cooling condenser as the engine heat exchanger-condenser. Said working fluid is the liquefied propane C3H8.

EFFECT: heat recovery, extra electric power generation.
