When evaluating a thermal system, exergy analysis is performed in addition to energy analysis to determine the location and quantity of losses in the system. In this study, energy, exergy, exergoeconomic and exergoenvironmental analyses of Orhaneli thermal power plant located in Bursa are carried out. In exergy analysis, physical and chemical exergies are taken into consideration and potential and kinetic exergies are neglected. Exergoeconomic analysis is conducted by using specific exergy costing (SPECO) method and cost values corresponding to each exergy flows are calculated. According to exergoeconomic analysis, unit exergy cost and exergy cost of steam sent to high-pressure turbine are calculated as 17.94 $/GJ and 22,854 $/h, respectively. The highest exergoeconomic factor is measured in pump (P2) and followed by P3. For the life cycle assessment (LCA) analysis, eco-indicator 99 impact assessment method is selected. LCA results are transferred to exergy flows and then exergoenvironmental analysis is performed. Environmental impact per exergy unit and exergetic environmental impact rate of the steam sent to high-pressure turbine are calculated as 14,680 mPts/GJ and 18,700 Pts/h, respectively. The highest exergoenvironmental factor is measured in pump (P2) and followed by P3.

在评估热力系统时，除了能量分析外，还要执行火用分析以确定系统中损失的位置和数量。在这项研究中，对位于布尔萨的 Orhaneli 热电厂进行了能源、火用、火用经济和火用环境分析。在火用分析中，考虑了物理和化学能，而忽略了势能和动能。使用特定火用成本（SPECO）方法进行火用经济分析，计算每个火用流量对应的成本值。根据火用经济学分析，送入高压汽轮机的蒸汽的单位火用成本和火用成本分别计算为17.94 $/GJ和22,854 $/h。泵中测量的最高工效经济系数 ( P2) 然后是P 3. 对于生命周期评估(LCA) 分析，选择eco-indicator 99 影响评估方法。LCA 结果被转移到火用流，然后进行火用环境分析。送至高压汽轮机的蒸汽单位火用环境影响和火用环境影响率分别计算为 14,680 mPts/GJ 和 18,700 Pts/h。在泵 ( P 2) 中测量到最高的运动环境因子，其次是P 3。
