摘　　要：基于热力学第二定律,针对燃气轮机实际简单循环,推导出燃气轮机各部件做功能力损失的计算公式。通过对某型燃气轮机的定量计算,得出燃气轮机在不同大气温度下的做功能力损失。结果表明,大气温度对燃气轮机的做功能力损失有较大的影响。Based on the Second Law of thermodynamics,the analytical formulae about exergy losses in some components of a real simple gas turbine were derived.The exergy losses in some different atmosphere temperature were studied by detailed numerical examples of a real gas turbine.The results indicate that the atmosphere temperature has strong effect to the exergy losses of gas turbine.

关 键 词：大气温度 燃气轮机循环 做功能力损失
