摘要
对带涡轮进气冷却的燃气轮机循环进行了分析,导出了循环效率和损失的表达式,分析了循环温比和质量流率比对循环效率和循环输出比功的影响。得到了该循环的效率特性和输出比功特性,确定了损失最大的位置,研究对燃气轮机循环的设计有一定指导意义。
The exergy analysis is carried for a Brayton cycle with turbine gas cooling, and the analytical formulae about exergy efficiency and specific work of the cycle are deduced. The effeets of ehanges of the temperature ratio and mass flow ratio on the performance of the are analyzed. The performance of exergy effieieney and specific work are obtained. Moreover, the largest exergy loss location for the design of gas turbine cycles. is determined. The results obtained in this paper may provide some guidelines
