摘　　要：基于热力学第二定律,对燃气轮机实际简单循环推导出了燃气轮机各部件火用损失的计算公式。通过对某型燃气轮机的定量计算,得出了燃气轮机在不同燃气初温下的火用损失。结果表明,燃气初温对燃气轮机的火用损失有较大的影响。Based on the second law of thermodynamics, the analytical formulae about exergy losses in some components of a real gas turbine cycle are derived. The exergy losses in some different gas temperatures are studied by detailed numerical examples of a real gas turbine. The results indicate that the initial gas temperature has strong effect to the exergy losses of gas turbine.
