摘　　要：冷却空气量是影响燃气轮机性能的关键因素,透平冷却技术研究的重点方向是以最少的冷却空气量来达到最好的冷却效果,才能使燃气轮机性能达到先进水平。对市场上具有代表性的某些型号的燃气轮机冷却空气量进行了推算,并对300 MW等级燃气轮机在不同透平初温、不同冷却空气量下的性能进行了计算,对透平初温、冷却空气量对机组循环性能的影响进行了定性分析。The amount of cooling air is an important factor to affect the gas turbine performance. Therefore, the main research direction of cooling technology is how to achieve the best cooling effect with the least amount of cooling air and get the advanced overall performance of the gas turbine. The amount of cooling air of some typical gas turbine currently on the market and performance have been calculated and an ana]ysis of 300 MW power class gas turbine under different cooling air amount and different firing temperature have been conducted.
