Abstract (2. Language): 
The share of electricity production from thermal power plants for Turkey is about 61 %. Since the fossil fuels are rapidly consumed, the concept of fossil fuel saving is very important for humanity. In this paper, the effects of boiler feed water preheating by means of geothermal brine on overall performance and fossil fuel savings in thermal power plants are examined. According to the performed analysis, power plant thermal efficiency could be increased of 2-4 % via geothermal preheating. In this analysis, a hypothetical thermal power plant is considered and its performance is evaluated. According to analysis, 1 million US$ in fossil fuel savings and 4.1 % increase in thermal efficiency could be achieved by the use of geothermal preheating.

Abstract (Original Language): 
Ülkemizin elektrik enerjisi ihtiyacını karşılamada termik santralların payı % 61'dir. Termik santrallarda kullanılan fosil yakıtların hızla tükenmesi, yakıt tasarrufunun önemini ortaya koymaktadır. Bu çalışmada termik santrallarda kazan besleme suyunun, düşük sıcaklıklı jeotermal kaynaklardan yararlanarak ön ısıtılmasının, santral genel verimi ve yakıt tasarrufu üzerindeki etkileri incelenmiştir. Yapılan analizlere göre bir termik santralda, jeotermal ön ısıtma ile sağlanacak verim artışı % 2-4 aralığında olmaktadır. Bu çalışmada incelenen ve klasik Rankine çevrimine göre çalışan bir kömür yakıtlı termik santralın, jeotermal ön ısıtma ile yıllık parasal yakıt tasarrufu yaklaşık olarak 1 milyon US$ ve verim artışı da % 4.1 olmaktadır.
