压气机级间喷水燃气轮机循环分析

该文给出压气机组间喷水燃气轮机数学模型，并据此模型计算出压气机的出口温度、压缩功、涡轮进口温度、循环效率及输出功率随喷水量变化关系。分析了大气温度、压比及涡轮进口温度变化时的压气机级间喷水燃气轮机的性能变化规律，讨论了在压气机不同位置喷水对燃气轮机比功和循环效率等性能的影响。

Cycle Analysis of Gas Turbine with Water Injection into Inter-Stage of its Compressor

In this paper,a mathematical model of gas turbine with water injection into inter stage of its compressor is given,and relationships of compressor exit temperature,compression work,turbine inlet temperature,total efficiency and output power with the quantities of injected water are calculated by using the model.The performance variation of the gas turbine with water injection into inter stage of compressor was analyzed under changed atmospherical temperatures,compression ratios and turbine inlet temperatures.The effect of location of water injection on the specific work and cycle efficiency is discussed.Some conclusions of effects of water injection into inter stage of compressor are obtained,and foundation for further researche is laid.
