锅炉侧汽水管道连通管热膨胀位移故障原因分析与处理

摘要

In view of the steam-water conecting pipes thermal expansion displacement fault on a circulating fluidized bed boiler, the fault cause analysis and pipeline stress calculation was made, determined the cause reasin was that the hanger design work load was too large; and through contrast of the pipeline stress and force/moment, showed the harm of pipeline thermal expansion displacement blocked. By replacement of the right hangers through selection, eliminated the problems of pipeline thermal expansion displacement blocked.%针对某循环流化床机组锅炉侧汽水管道连通管热膨胀位移异常故障，进行了故障原因分析与管道应力计算，确定故障原因为吊架的设计工作载荷过大；并通过管道应力、推力/推力矩对比，说明了管道位移受阻带来的危害。通过重新选型更换合适的支吊架，彻底消除了管道热膨胀位移受阻问题。
