Düşük Enerji Seviyeli Kaynakla Çalışan Afyon Jeotermal Güç Santralinin Performans Değerlendirilmesi

Abstract

Exergoeconomic performance evaluation of 2700 kW binary cycle design geothermal power plant in western Turkey is conducted using actual plant operating data, and potential improvements are identified. Afyon Geothermal Power Plant is thermodynamically modeled in a computer environment using current working parameters in a comprehensive way for the use of geothermal energy in electricity generation. To simulate the plant during thermodynamic conditions with exergoeconomic analysis, the Engineering Equation Solver (EES) software is used. Geothermal water temperature and mass flow rate of the plant are 110°C, and 150 kg/s, respectively. Energy and exergy efficiencies of the plant are calculated as 10.4%, and 29.7%. The potential annual revenue of geothermal electricity is calculated to be 2,880,277 $/yr. The exergetic cost of the electricity from the plant is calculated as 0.0233 $/kWh, respectively.
