摘　　要：有效能分析法是建立在热力学第一、第二定律上的能量的"数"与"质"统一的分析方法。有效能分析法克服能量衡算法和熵分析法存在的缺陷,揭露外部有效能损失和内部不可逆因素(传热、燃烧、传质和流动等)引成的有效能损失,确定排出的物流有效能和能流有效能的可用性,以及由此造成的有效能损失,对过程和装置的热力完善程度和节能潜力进行正确分析和评价。有效能分析法的应用范围很广,从制氢工艺、发电厂、锅炉、生物质能生产、热交换器、发动机以及蒸馏过程的节能分析到环境和生态系统的评价,说明有效能分析法在节约能源、促进可持续发展过程中起着重要的作用。Exergy analysis is based on the first law of thermodynamics and the second law of thermodynamics. ＂Quantity＂ and ＂quality＂ of energy are unified in exergy analysis. Exergy analysis overcomes the defects of energy analysis and entropy analysis, reveals the external exergy loss and the exergy loss caused by internal irreversible factors. The exergy availability and exergy loss of the discharged material and energy flow could be determined. The perfection degree of thermodynamic and energy-saving potential of process and apparatus could be analyzed and evaluated properly. Exergy analysis could be applied in many fields, from the energy-saving analysis of hydrogen production, power plants, boiler, biomass energy production, heat exchangers and engine, the distillation process to the environment and ecosystem evaluation. Exergy analysis plays an important role in energy conservation and promotion of sustainable development.
