 Performance evaluation of a single-flash geothermal power plant in Denizli, TurkeyY. Cerci Energy, 2003, vol. 28, issue 1, 27-35 Abstract: The performance of an 11.4 MW single-flash geothermal power plant in Denizli, Turkey, along with major plant components, was evaluated by using exergy analysis based on actual plant operation data. The geothermal power plant operation is described by following the flow of the geofluid, and the exergies of the geofluid at major plant locations are calculated and presented in tables. Exergy destruction from the wellhead to the discharge of steam is quantified and illustrated using an exergy flow diagram. Major exergy destructions occurred due to the separation of steam from the geofluid, the discharge of the brine from the separator, turbine, generator and compressor inefficiencies, and the discharge of steam to the environment. The largest exergy destruction occurred during the discharge of the brine into the Menderes river. This amounted to 46.9% of the total energy input. The second law efficiency of the plant was calculated to be 20.8%. The comparison of the efficiency with other geothermal power plants revealed that the plant efficiency is low, and therefore alternative designs were investigated to improve its performance.
