V94·3A燃气轮机天然气疏水系统运行中跳机信号的分析与处理

Erection and Commissioning of Natural Gas Drainage System of V94.3A Gas Turbine

由于V94.3A燃气轮机在预混燃烧(Premix Model)方式下可能会在扩散燃烧(Diffusion Model)管路中产生凝结物,因此在燃烧模式由较长时间PM运行之后向DM转化过程中,管中的凝结物可能会对DM燃烧产生不利影响,所以该燃机天然气管路系统专门配备有一个疏水模块。文章首先对该模块的组成和功能进行系统介绍,然后重点对运行过程中出现的导致跳机的原因进行分析和纠错处理。

For the V94. 3A gas turbine, during operating in premix mode,the accumulation of condensation may occur in the diffusion gas piping, The amount of condensation may affect the flames when the DM burners are reactivated after a long period of operation in PM.So a drainage system is designed for the natural gas system. The article first briefs the configuration and function of the drainage module and then emphasizes the cause analysis and correcting measures of the trip signal.
