S109FA燃气轮机燃烧故障的分析与处理

Analysis and Handling of the Combustion Fault in a S109FA Gas Turbine

分析了S109FA单轴燃气蒸汽联合循环发电机组在运行中出现的燃气轮机排气温度分散度大故障和机组在燃烧模式切换时发生分散度大或熄火导致机组跳闸的原因,提出了故障处理方法,并对如何从根本上解决燃气轮机运行的可靠性问题提出了一些建议。

The fault of large temperature dispersion of exhaust gas from gas turbine and the reasons of unit tripping led by the large dispersion degree or flameout have been analyzed during combustion mode switching of a S109FA single-shaft gas-steam combined cycle generating unit.The handling ways have been put forward and some suggestions have been provided completely so as to raise the operational reliability of the gas turbine.Since the unit is a localized one of PG9351FA model,the suggestions will contribute to the development of localized gas turbines.
