摘要
针对燃气轮机进气冷却的效果在不同大气参数下变化很大的问题,对燃气轮机进气冷却装置的热力过程、影响因素、经济效果等方面进行了研究。基于某电厂燃气轮机和燃气-蒸汽联合循环机组的运行数据,利用热平衡仿真软件Gate Cycle对两种发电机组系统进行模块化建模,并增加进气冷却装置,定量分析了两种发电机组进气被冷却后输出功率的增加量(即进气冷却效果)在不同大气参数(温度、相对湿度和压力)下的变化情况。研究结果表明,大气参数的变化,会对燃气轮机进气冷却的效果产生很大影响,两者之间呈现出一定的数值关系。
Aiming at analyzing the effects of atmospheric parameters on gas turbine inlet air cooling technology（GTIAC）,the thermodynamic process,influencing factors and economic effects of GTIAC were studied. Based on the operating parameters of turbine and gas- steam combined cycle unit in a certain power plant,the system models of two kinds of power units were built in modular modeling method by Gate Cycle software,a thermal equilibrium simulation software,and GTIAC equipment was installed. The output power increase of these two kinds of power units after cooling inlet air（inlet air cooling effects）under different atmospheric parameters（temperature,humidity and pressure）was analyzed quantitatively. The results indicate that the change of atmospheric parameters has a great effect on the gas turbine inlet air cooling effects,showing a certain numerical relationship between them.
