化石燃料储量（煤、石油、天然气等）日益减少。此外，技术的快速进步导致所需能源的增加。这种新情况导致可再生能源的重要性日益增加，各种系统正在开发有效利用这些可再生能源。本文介绍了该地区Aydın-Salavatli地热田的特征及DORA 1和DORA 2两座电厂的工作原理。电厂的能量和火用效率计算的重点是电厂使用的热流体的影响。此外，本研究还发现了一些相关性。确定了造成火用损失的电厂区段。据此，本研究提出了改进建议。同时考虑电厂的投资成本和设备维护成本，进行了工作经济性分析。
Fossil fuel reserves (coal, oil, natural gas, etc.) diminish day by day. In addition, rapid advancement of technology causes an increase in the amount of energy needed. This emerging situation resulted in ever increasing importance of renewable energy sources, and various systems are being developed to utilize these renewable energy sources effectively. In this study, information about Aydın–Salavatli geothermal field’s features and working principles of the 2 power plants (DORA 1 and DORA 2) in the region are given. Power plants’ energy and exergy efficiencies were calculated with the emphasis on the effects of thermal fluids used in power plants. Also, in this study, some correlations were developed. Power plants’ sections which cause exergy losses were identified. Accordingly, improvement suggestions were presented in this study. Additionally, exergoeconomic analyses were conducted while power plants’ investment costs and equipment maintenance costs were taken into consideration.
