高炉透平机振动异常故障判断及处理

DIAGNOSIS AND HANDLING OF ABNORMAL VIBRATION FAULTS IN BLAST FURNACE TURBINES

广西柳钢中金不锈钢有限公司炼铁厂2号高炉配1套高炉TRT发电机组,主要利用高炉煤气所具有的压力能和热能,通过透平膨胀做功,带动发电机发电,进行能量回收利用的一种节能装置,很大程度解决了冶金行业的用电自给问题。一旦透平机机组不能正常运行,将导致高炉煤气余压无法实现动能转化,公司将每天损失5万元电费。以广西柳钢中金不锈钢有限公司炼铁厂2号高炉TRT透平机故障为例,着重介绍燃气涡轮机故障诊断、故障排查及原因分析、振动频谱分析等,分析透平机振动异常原因,采取相应措施取得了良好效果,为同类问题的处理提供了分析思路。

Guangxi Liugang Zhongjin Stainless Steel Co.,Ltd.'s Blast Furnace No.2 Ironmaking Plant is equipped with a set of TRT generators for the furnace,which mainly uses the pressure and heat energy of the blast furnace gas to generate electricity through turbine expansion and drive the generator to achieve energy recovery.This is an energysaving device that largely solves the problem of power self-sufficiency in the metallurgical industry.Once the turbine unit fails to operate properly,the excess pressure of the blast furnace gas cannot be converted into kinetic energy,and the company will lose 50000 yuan in electricity bills every day.This article focuses on the diagnosis of gas turbine faults,troubleshooting and root cause analysis,vibration spectrum analysis,and other related topics.Using the example of the TRT turbine failure in the No.2 blast furnace of Guangxi Liugang Zhongjin Stainless Steel Co.,Ltd.'s ironmaking plant,the article analyzes the cause of abnormal turbine vibration and takes appropriate measures to achieve good results,providing analysis ideas for similar problems.
