摘要
燃气轮机的可靠性在很大程度上取决于热端部件的技术状态和维修水平。本文首先分析了影响燃机热端部件寿命的三项主要因素,并在此基础上详细讨论了各种常用的燃气轮机的寿命评估方法。针对惠州LNG电厂M701F型燃气-蒸汽联合循环机组特点,提出了基于等效运行时间分析的燃机寿命评估法。案例计算结果显示等效运行时间分析法是一种简单、实用的评价方法。
The reliability of the gas turbine depends on the technical status and the maintenance level of the hot-end components in a large part.The three main factors in? uencing on the service life of the hot-end components of the gas turbine were analyzed fi rst.On this basis,various common service life assessment methods for gas turbine were discussed in detail.Aiming at the features of the M701F gas-steam combined cycle unit in Huizhou LNG power plant,a gas turbine life assessment method based on equivalent oper...
