燃气轮机入口空气系统的冷却改造

针对燃气轮机在高环境温度下输出功率不足的问题进行分析，提出了一些可以增加燃气轮机输出功率的办法，认为利用装置本身富余的冷冻能力来冷却燃气轮机的入口空气，是提高燃气轮机输出功率的最好办法。设计冷却方案和进行相关的工艺计算，利用生产装置大修的机会成功地实施了改造，经过近一个月的运行，效果相当明显。

COOLING REVAMP OF INLET AIR SYSTEM OF GAS TURBINE

This paper analyzes the issue of inadequate output power of gas turbine at higher atmospheric temperature,and presents some ways to increase the power.The best way is to cool the inlet air of gas turbine by using surplus cooling capacity of the plant itself.The cooling scheme was designed with relevant calculation.The revamp was successfully implemented during the overhaul of the plant.The nearly one month operation indicates that the revamp has obtained obvious results.
