Abstract:
1. A geothermal based, binary cycle power plant, comprising: a preheater connected to receive geothermal liquid or brine for preheating an organic motive fluid; a first vaporizer connected to receive geothermal steam for vaporizing organic motive fluid pre-heated in the pre-heater; a second vaporizer connected to receive geothermal steam for vaporizing organic motive fluid; first and second organic vapor turbines operating in parallel and coupled to a common generator, each of said turbines being connected to receive the vaporized organic motive fluid from a respective one of said first and second vaporizers, to drive each turbine; first and second recuperators connected to receive heat depleted organic fluid vapor respectively exiting the first and second organic vapor turbines, for heating organic motive fluid condensate; and first and second condensers for condensing the heat depleted organic motive fluid exiting said first and second recuperators, respectively, to provide the organic motive fluid condensate, wherein said second recuperator is connected to receive organic motive fluid condensate exiting the first recuperator, and wherein the preheater is connected to receive the organic motive fluid condensate from the second recuperator, to be preheated therein.
