Influence and Economic Analysis of Compression Ratio for Gas Turbine Efficiency and Specific Work

近年来,环境污染迫在眉睫,节能减排势在必行。为使燃气-蒸汽联合循环电厂投资少、效率高、运行之后有良好的经济效益,对其影响因素进行分析优化至关重要[1]。文章通过对燃气轮机回热循环、回热-间冷循环及回热-间冷-再热循环的理论分析,给出提高燃气轮机热力性能的优化计算案例,得出燃机热力循环过程中压缩比分配对热效率及比功的影响,并提出相关的优化结论。

In recent years,environmental pollution is around the corner,it is imperative to save energy and reduce emission.In order to make gas-steam combined cycle power plant less investment、high efficiency and great economic benefit after operation,it is becoming increasingly significant to analyze the factors of affecting optimization.Based on the theoretical analysis of gas turbine heat recovery cycle,heat recovery-intercooling cycle and heat recovery-intercooling-reheat cycle,this paper gives an optimization calculation case to improve the thermal performance of gas turbine,obtains the influence of compression ratio matching thermal efficiency and specific work in the process of gas turbine thermal cycle,and puts forward relevant optimization conclusions.
