摘　　要：对功热并供回热注水燃气轮机热力循环进行了基本定量分析 ,主要分析了注水率和压比对比功和供热量的影响。以总能利用率和当量火用效率为评价准则讨论了注水率和压比对循环性能的影响。This paper gives a fundamental quantitative analysis of the cycle of recuperative gas turbine cogeneration with water injection and mainly discusses the influence of water injection ratio and pressure ratio on the specific power and the amount of heating.At the same time,using the total energy efficiency and the equivalent exergy efficiency as the evaluation criterion,this paper discusses the influence of the water injection ratio and pressure ratio on the performance of this cycle.
