环境温度对PG6111FA型燃气轮机影响的分析

Analysis of the Influence of Air Temperature on PG 6111 FA Gas Turbine

针对燃气轮机机组在夏季高温环境下长时间运行时,无法达到进气温度的要求,造成机组出力严重受限,影响其调峰能力的问题,文章以PG6111FA型燃气轮机机组为例,分析环境温度对燃气轮机负荷影响的原因及对联合循环发电机组出力的影响,并提出利用进气冷却装置对压气机进气温度进行冷却来提高燃气轮机出力的解决措施。

As the gas turbine unit cannot meet the requirements of the intake temperature when it runs for a long time in hot summer the output of the gas turbine unit is seriously limited and its peak-shaving capacity is also affected.In view of the problem,this paper,taking PG6111FA gas turbine as an example,analyzes the reasons for the influence of air temperature on the load and the output of combined generator unit.The solution to improve the output of gas turbine is proposed by using the air intake cooling device to cool the inlet air of the compressor.
