| 摘 要： | 通过对典型燃气轮机总能系统热力学分析,认为(火用)效率是各类燃气轮机总能系统具有可比性的热力学完善性指标,通过(火用)分析可查明(火用)损失分布。文中指出提高(火用)效率的主要途径是提高燃气透平进气温度,它是影响总能系统(火用)效率的主要因素,而余热的利用方式对其影响不大。从热能综合利用的角度来看,总能系统宜兼有高的热利率与(火用)效率,因此,对总能系统进行能分析仍属必要。

| Abstract: | This paper puts forward that exergy efficiency is a measure of thermodynamic completness, which makes the total energy systems of all kinds of gas turbines comparable by means of thermodynamic analyses. With the help of exergy analysis, the distribution of exergy losses can be determined. The investigation shows that the main way of raising exergy efficiency is to raise the inlet temperature of turine, the main factor affecting the exergy efficiency of the total energy system. The utilization of waste heat of ths total energy system has no large effect upon exergy efficiency. From the point of view of comprehensive utilization of energy, it is still necessary to carry out the energy analysis to total energy systems, since the total energy systems must have both high thermal utilization coefficient and high exergy efficiency. |
