摘　　要：提出利用天然气经透平膨胀机降压产生的冷能降低燃气轮机进气(空气)温度。结合工程实例,介绍燃气轮机进气冷却系统流程,计算进气冷却系统的冷负荷与调压工艺的制冷能力。采取进气冷却后,燃气轮机实际输出功率平均提高8.3%。It is put forward that cold energy generated by natural gas turbo expander depressurization is used to reduce the inlet air temperature of gas turbine. Combined with an engineering examples, the flow process of inlet air cooling system of gas turbine is introduced, the cooling load of inlet air cooling system and refrigeration capacity of pressure regulation process are calculated. After cooling of inlet air, the actual output power of gas turbine increases by 8.3 % on an average.
