Patent ID: 7841179

Claim:
An apparatus for increasing power output of small internal combustion electric generators comprising: a heat exchange/condensation component including: a condenser HE 1 , two recuperative heat exchangers HE 2 and HE 3 , a separator S 1 , and and two pumps P 1 and P 2 , where: the heat exchange/condensation component converts a spent intermediate working solution stream into a very rich working solution stream and a lean working solution stream, where a portion of the lean working solution stream and the very rich working solution stream are combined to form a rich working solution stream, heat from the spent intermediate working solution stream prior to separation and heat from the rich working solution stream are used to heat and partially vaporize a fully condensed, higher pressure, rich working solution stream, and the pumps increase a pressure of the remainder of the lean working solution stream to form a higher pressure, lean working solution stream and a pressure of the fully condensed, rich working solution stream to form the fully condensed, higher pressure, rich working solution stream; a recuperative heat recovery vapor generator RHRVG adapted to form a fully vaporized, intermediate working solution stream with heat derived from an external heat source stream and from the spent intermediate working solution stream prior to partially vaporizing the fully condensed, higher pressure, rich working solution stream, and a turbine T 1 adapted to convert a portion of thermal energy in the fully vaporized, intermediate working solution stream into a useable form of energy producing the spent intermediate working solution stream.
