摘　　要：将实际循环在循环完善程度和设备完善程度方面与理论的卡诺循环进行对比 ,通过循环的特性参数估算出闭式注蒸汽燃气轮机循环的热效率 ,并在此基础上给出了中冷、再热和燃煤气的闭式注蒸汽循环热效率的估算公式 。A real cycle was compared with a theoretical Carnot one in terms of cycle and equipment soundness and intactness. By way of the cycle characteristic parameters evaluated was the thermal efficiency of a closed-cycle steam injected gas turbine. On this basis a formula was given for evaluating the thermal efficiency of a closed-cycle gas-fired steam injected gas turbine with intercooling and reheat. Meanwhile, also analyzed was the effect on the cycle thermal efficiency of the cycle and equipment soundness and perfection factor.
