摘要： Disclosed herein are various systems and methods for producing mechanical power from a heat source. The system may include a heat recovery heat exchanger, a turbine, a condenser heat exchanger, and a liquid circulating pump, etc. In other embodiments, a desuperheater or an economizer, or both, may be employed. In one illustrative embodiment, the system comprises a first heat exchanger adapted to receive a fluid from a heat source and a working fluid, wherein, when the working fluid is passed through the first heat exchanger, the working fluid is converted to a vapor via heat transfer with the fluid from the heat source, at least one turbine adapted to receive the vapor, and an optional economizer heat exchanger adapted to receive exhaust vapor from the turbine and the working fluid, wherein a temperature of the working fluid is adapted to be increased via heat transfer with the exhaust vapor from the turbine prior to the introduction of the working fluid into the first heat exchanger. The system further comprises a condenser heat exchanger that is adapted to receive the exhaust vapor from the turbine after the exhaust vapor has passed through the optional economizer heat exchanger and a cooling fluid, wherein a temperature of the exhaust vapor is reduced via heat transfer with the cooling fluid, and a pump that is adapted to circulate the working fluid to the optional economizer heat exchanger.

摘要：　火力発電プラントは、蒸気発生装置であるボイラ、高圧タービン、低圧タービン、復水器、低圧給水加熱器及び蒸気ヒートポンプ装置を備えている。ボイラで発生した蒸気は、高圧タービン及び低圧タービンに供給され、復水器で凝縮される。復水器から排出された給水は、低圧給水加熱器で低圧タービンからの抽気蒸気で加熱される。さらに、この給水は、下流に位置する蒸気ヒートポンプ装置で加熱され、ボイラに供給される。蒸気ヒートポンプ装置は、複数の圧縮機、及び圧縮機毎に設けられて内部に伝熱管を設けた凝縮器を有する。低圧タービンから抽気された蒸気は、各圧縮機に順番に供給されて圧縮され、温度が上昇する。上流の圧縮機から排出された蒸気は、凝縮器内で伝熱管内を流れる給水によって一部が凝縮され、下流の圧縮機に導かれる。伝熱管内を流れる給水は蒸気によって加熱される。

摘要： A closed thermodynamic system for producing electricity, including a water pump (180), a water circulation heater (110), a steam turbine (120), an electric generator (130) and a steam/water cooling sub-system (190). The water pump transfers water, having about ambient temperature, extracted from the steam/water unit to the water heating unit (165), which heats up the water that flows into the cooking sub-system (190). The water circulation heater (110) converts the water into high pressure steam which is directed to the steam turbine which converts the thermal energy to kinetic energy. The rotating turbine rotates the electric generator (130), being affixed onto the rotational axis of the turbine, and the electric generator produces electric energy. The water cooling sub-system then reduces the steam returning from the turbine into water having about ambient temperature.
