ABSTRACT:
A method and apparatus for converting thermal energy into electric power. A high pressure gaseous working stream is expanded, producing a spent stream. The spent stream is condensed, producing a condensed stream. The condensed stream forms first and second partially evaporated streams, which in turn form first and second vapor streams and first and second liquid streams. A rich stream is generated from the first vapor stream. A lean stream is generated from combining the second vapor stream with a mixing stream. The resulting rich and lean streams are passed through a boiler where they are evaporated. After exiting the boiler, the evaporated rich stream is combined with the evaporated lean stream generating the high pressure gaseous working stream, completing the cycle.
