  • Patent number: 8601814
    Abstract: A geothermal based, binary cycle power plant is provided, comprising: a vaporizer for vaporizing pre-heated organic motive fluid by means of geothermal steam; two organic vapor turbines operating in parallel and coupled to a common generator, each of said turbines being driven by vaporized organic motive fluid supplied to each turbine; two recuperators for heating the organic motive fluid by means of a corresponding organic vapor turbine discharge; and two condensers for condensing heat depleted motive fluid exiting said two recuperators, respectively. A geothermal steam condensate recovery system is also provided, comprising a source of geothermal steam for vaporizing a organic motive fluid and producing geothermal steam condensate, and conduit means through which geothermal steam condensate is delivered to a supply of cooling liquid used to condense the organic motive fluid, the delivered geothermal steam condensate serving as make-up liquid for evaporated cooling liquid.
