进气冷却与湿化压气机技术在燃气轮机上的应用

Application of Inlet Air cooling and Humidifying Compressor Technique on Gas Turbine

燃气轮机是燃气-蒸汽联合循环发电机组的主要设备,在燃气轮机上加装进气冷却与湿化压气机设备,高温天气情况下,能够有效地降低燃气轮机压气机运行温度,提高燃气轮机出功。介绍了燃气轮机采用进气冷却与湿化压气机技术的设计原理,设备优点以及各部分系统的组成。该设备在济钢集团PG6561L机组上使用后,出功明显增加,效果显著。

The gas turbine is the main equipment of gas-steam combined cycle type generator set. Adding inlet air cooling and humidifying compressor at gas turbine can effectively lower the running temperature of the compressor and raise gas turbine work under high temperature weather. The paper introduces the design principle, equipment characteris tics and consisting systems of inlet air cooling and humidifying compressor technique. The said equipment, applied at PG6561L generator set at Jigang Group, gives much more work and provides prominent effect.
