摘　　要：讨论燃气轮机湿空气回注循环，提出分为内部和外部空气加湿回注循环两类。以部分空气回热回注循环（PRSTIG）为基础，分析了燃气初温、压比、回注比、回热比等参数对循环效率、比功的影响。通过对两类各相关循环的特点的比较、讨论，得出的结论是：湿空气回经循环可使功率提高10％～25％，热耗降低6％～15％，NOx排放量降低15％～50％．而且均可在现行装量上改造实施。A gas turbine humid-air injected cycle is discussed with the assertion that there are two kinds of injected cycle,namely,internal and external humid air injection.On the basis of a partial regenerative steam injected gas turbine(PRSTIG) cycle analyzed is the impact of such parameters as turbine entry temperature,pressure ratio,injection ratio and regeneration ratio,etc on cycle efficiency and specific work.Through a comparison and discussion of the specific features of the two relevant cycles the authors have come to the conclusion that the humid air injected cycle makes it possible to enhance output power by 10%～25%,reduce heat consumption rate by 6%～15% and NO_x emissions by 15%～50%.Moreover,the abovementioned modification can be implemented on existing power plants.
