摘要:

为节省启动能耗,缩短锅炉启动时间,启动过程中提前投入高压加热器系统,由于给水流量较小、管道全冷态等原因,启动过程中正常疏水管道经常出现强烈振动,引起设备损坏并带来安全隐患。分析了管道振动的原因,采取了相应的技改及运行调整措施,有效杜绝了高压加热器启动过程中管道的振动。

Abstract:

To save startup energy and shorten boiler startup time, high pressure reheater was put into operation in advance in startup stage. Due to small water flow and full cold state, dewater pipeline usually serious vibrates during startup. After analyzing vibration causes, technical improvement was carried out accordingly. Vibration of high pressure reheater in startup stage was eliminated.
