| Abstract | Ormat initiated facility expansion projects at both the Heber-1 double flash power plant and in Geo East Mesa or GEM double flash power plant which is part of the East Mesa complex. These projects were based on utilization of the spent brine, (which is sent for injection after the second flash stage of the existing steam turbines,) to generate additional electricity by means of an Ormat Energy Converter (OEC) which utilizes the organic Rankine cycle. However the injection systems were identified as one of the areas which require special attention, especially with regard to the efficiency of the injection booster pumps. In this presentation we describe a scheme to utilize the organic Rankine cycle bottoming turbine system to drive the brine booster injection pumps directly in a more efficient manner than with a direct electric motor drive. |
