摘　　要：基于[火用]分析理论,推导出汽轮机[火用]损计算模型,并将其应用于供热汽轮机改造经济性分析过程中。结果表明:[火用]分析法弥补了热力学第一定律方法的不足,能够准确揭示系统装置中[火用]损失的大小、分布和影响因素,指出热力过程或循环改进的可能性。Based on the theory of exergy analysis, a calculation model of exergy loss was derived and then used in economic analysis for retrofit of a cogeneration turbine. Results show that the method of exergy analysis makes up for the deficiency of the first law method of thermodynamics, which can accurately determine the volume, distribution and influence factors of exergy loss for relevant systems and facilities, pointing out the possibility of improvement for thermal processes or cycles.
