Heat engine cycle for power station - has steam cycle refrigerant cycle and heat pump operated in cascade

摘要

Steam generated in a boiler passes through superheaters to two double acting steam engines which drive an electrical generator. The exhaust is condensed in a condenser and returned to the boiler through feed water heaters. The heat given up in the condenser is used to evaporate a refrigerant which passes through superheaters to two double acting vapour engines which drive a second electrical generator. The exhaust from these engines is condensed and returned to be evaporated in the steam condenser. The heat given out in the refrigerant condenser is used as the source for a heat pump.
