摘　　要：对燃气-蒸汽联合循环加装进气冷却装置,可以在夏季高温时期增加机组出力,满足调峰需要。介绍了几种燃气轮机进气冷却技术,并对其进行比较,提出了一种冷却燃机进气的方法——热管废热利用型LiBr吸收式制冷。该方法充分利用了电站低品位热能,使工质传热效率高、设备运行可靠、设备运行及维护费用低。The output of the gas turbines will be reduced with the raise of the inlet air temperature. Cooling the turbine inlet air can increase output power substantially during the summer season. Several inlet air cooling technologies were introduced and compared. One new technology for cooling the inlet air was proposed which is LiBr absorption chiller with heat pipe exchanger, where the exhaust heat can be used abundantly. It should be the ideal choose for the inlet air cooling with its high heat transfer efficiency, credibility of running, low cost of working etc.
