【摘要】 文中首先从部件的热平衡角度出发对注蒸汽燃气轮机（ＳＴＩＧ）循环进行了热力学分析，建立了相应的热力过程计算模型，在压比π＝８～４８，透平进口温度ＴＩＴ＝９００～１３００℃的宽广范围内对ＳＴＩＧ进行了性能模拟，对最佳注汽量和性能之间的关联进行了广泛深入的研究。更多还原

【Abstract】 First, a thermodynamic analysis from the viewpoint of components heat balance is conducted of a steam injected gas turbine (STIG) with a corresponding thermodynamic process calculation model being set up. Within a wide range of pressure ratio π=8～48 and turbine inlet temperature TIT=900～1300℃ a performance simulation has been carried out for the STIG. An in depth and comprehensive study is conducted of the correlation of an optimum steam injection rate and gas turbine performance.更多还原
