摘　　要：在分析了给水加热型联合循环后 ,在我国具体情况下的应用前景的基础上 ,给出此种联合循环及其在用以增容改造已有的蒸汽轮机电厂时的性能简明示式和典型数据。The application prospect of feedwater heating type combined cycle in China is discussed. The concise performance expressions and typical data are analyzed for the combined cycle and for repowering the existed steam power station. It is found out that the power ratio between steam turbine and gas turbine for this combined cycle is about 3～4, the absolute efficiency gain after repowering is about 3%～4% and the efficiency optimum gas turbine pressure ratio of this type combined cycle is approximately equal to that of the simple cycle gas turbine.The expressions and figures shown in this paper are valuable to the preliminary feasible analysis for applying this type combined cycle.
