摘　　要：采用部件特性建模方法建立了燃气轮机的稳态模型。通过常规循环燃机与加入间冷回热循环燃机性能的对比分析发现间冷回热循环能够在显著提高燃机功率的同时降低耗油率,且通过间冷器和回热器的参数分析发现提高换热度和总压恢复系数能够改善燃机的总体性能;间冷回热循环下的压气机压比并不是越高越好,存在高压压气机和低压压气机的最经济压比使得燃机耗油率最低,且高压压气机和低压压气机的最经济压比数值较为接近;间冷回热循环能够较好的改善燃机的经济性,热效率可达46.71%,被证明是行之有效的改型升级措施,且能够降低技术风险。We established the steady state model of gas turbine in the paper by using the component characteristic modeling method.Through the comparison of the performance of the conventional cycle gas-turbine and the intercooled recuperated cycle gas-turbine,it was found that the intercooled recuperated cycle can significantly increase the engine power and reduce the specific fuel consumption.Through the parameter analysis of intercooler and recuperator,it was found that increasing the heat transfer degree and total pressure recovery coefficient can improve the overall performance of the gas turbine.The pressure ratio of the compressor is not the higher the better,the most economic pressure ratio of the high pressure compressor and the low pressure compressor makes the lowest specific fuel consumption,and the most economic pressure ratio of the high pressure compressor and the low pressure compressor is close.The intercooled recuperated cycle can better improve the economy of the engine,and the thermal efficiency can reach 46.71%.It is proved to be an effective upgrading measure and can reduce the technical risk.
