Performance Evaluation of a Geothermal Power Plant Using Energy and Exergy Analysis Methodology

Abstract

Artan enerji arzı daha fazla enerji üretimini beraberinde getirmektedir. Enerji üretimi için kısıtlı miktarda olan fosil yakıtlarının hem yakın zamanda tükenecek olması hem de çevresel sorunlara neden olması yenilenebilir enerji kaynaklarının araştırılmasını ve kullanımını arttırmıştır. Yenilenebilir enerji kaynaklarından biri de Jeotermal enerjidir Türkiye jeotermal enerji kaynağı bakımından dünyada 4. sırada yer almaktadır. Çalışmada Kütahya/Simav'da bulunan bir jeotermal kuyunun elektrik üretimi incelenmiştir. Bu jeotermal kuyuya entegre edilen elektrik üretim tesisinin tüm ana bileşenlerinin hem ekserji hem de enerji analizleri yapılmıştır. 409,2 kW türbin mekanik gücü ile 327,36 kW elektrik enerjisi elde edilmiştir. Ayrıca tüm sistemin verimi %0,785 ve ekserji verimi ise %4,59 olarak hesaplanmıştır.

Performance Evaluation of a Geothermal Power Plant Using Energy and Exergy Analysis Methodology

Abstract

Increased energy supply leads to increased energy production. The fact that fossil fuels, which are available in limited quantities for energy production, will be depleted in the near future and also cause environmental problems has increased the research and use of renewable energy sources. Geothermal energy is one of the renewable energy sources. Türkiye ranks 4th in the world in terms of geothermal energy resources. This study investigated electricity generation from a geothermal well located in Simav, Kütahya. Exergy and energy analyses have been performed on all the main components of the electricity generation plant integrated into this geothermal well. A turbine with 409.2 kW of mechanical power has generated 327.36 kW of electrical energy. Furthermore, the overall system efficiency was calculated as 0.785% and the exergy efficiency as 4.59%.
