Abstract
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 …
