摘要
针对某9FA燃机停机后缸温下降速度异常增大的问题,分析异常现象并查找原因,通过更换中压并汽阀成功解决了此重大缺陷,可为类似机组的缸温异常分析提供参考。
Aiming at the increased lowering speed of cylinder temperature of9FA gas turbine after shutdown,the paper analyzes the abnormity and detects the reasons.The defect is eliminated by replacement of medium-pressure steam converging valve,which can be referenced for temperature abnormity analysis of similar steam turbines.
