摘　　要：燃气轮机燃烧失稳会造成燃烧室内部剧烈扰动,甚至熄火停机。对不同燃气轮机燃烧失稳产生的机理进行分析,认为环形燃烧室更容易产生大幅燃烧波动,并会引发更为严重的热声振荡现象,损伤燃烧室及下游热通道部件。为了避免燃烧波动的产生,分析了燃烧失稳的原因,提出了相应的防范措施,对采用同类型燃气轮机的发电企业具有一定的借鉴意义。The combustion instability of gas turbine will cause severe disturbance in the combustion chamber and even shut down.The mechanism of combustion instability of different gas turbines was analyzed.It was considered that the annular combustion chamber was easier to produce large combustion fluctuation,which would lead to more serious thermoacoustic oscillation,damage the combustion chamber and downstream heat channel components.In order to avoid the generation of combustion fluctuation,the causes of combustion instability were analyzed,and the corresponding preventive measures were put forward,which can be used as a reference for gas-fired power generation enterprises using the same type of gas turbine.
