Dual reheat rankine cycle system and method thereof

摘要

A rankine cycle system includes a heater configured to circulate a working fluid in heat exchange relationship with a hot fluid to vaporize the working fluid. A hot system is coupled to the heater. The hot system includes a first heat exchanger configured to circulate a first vaporized stream of the working fluid from the heater in heat exchange relationship with a first condensed stream of the working fluid to heat the first condensed stream of the working fluid. A cold system is coupled to the heater and the hot system. The cold system includes a second heat exchanger configured to circulate a second vaporized stream of the working fluid from the hot system in heat exchange relationship with a second condensed stream of the working fluid to heat the second condensed stream of the working fluid before being fed to the heater.

1. A rankine cycle system, comprising:
a heater configured to circulate a working fluid in heat exchange relationship with a hot fluid to vaporize the working fluid; a hot system coupled to the heater; wherein the hot system comprises a first heat exchanger configured to circulate a first vaporized stream of the working fluid from the heater in heat exchange relationship with a first condensed stream of the working fluid, thereby heating the first condensed stream to produce therefrom a second vaporized stream of the working fluid; and a cold system coupled to the heater and the hot system; wherein the cold system comprises a second heat exchanger configured to circulate the second vaporized stream of the working fluid from the hot system in heat exchange relationship with a second condensed stream of the working fluid to heat the second condensed stream of the working fluid before being fed to the heater.
