基于开口稳定流系统分析燃气轮机异物损坏压气机叶片

Analysis of Compressor Blades Damaged by Foreign Matter in Gas Turbine based on Open Steady Flow System

本文应用开口稳定流系统方程推导了燃气轮机水洗喷嘴脱落没有掉落燃气轮机进气室底,反被高速气流携带进入压气机原因进行理论分析,同时针对燃气轮机喷嘴脱落事件重新制定了一系列标准,并提出改进措施,为同类型机组提供预防参考。

In this paper,the equation of open steady flow system is used to deduce the gas turbine s washing nozzles which doesn t fall off onto the bottom of inlet chamber of the gas turbine but is carried into compressor by high speed airflow theory analysis,at the same time for gas turbine nozzle loss events to formulate a series of standards,and put forward the improvement measure,prevention of reference for the same type unit.
