辅助锅炉省煤器导淋爆管分析与处理

摘要

针对辅助锅炉液位快速下降的现象，分析确认为省煤器低点排放管导淋出现应力性断裂引起泄漏。省煤器导淋由于长期处在酸性冷凝液中，逐渐腐蚀并减薄，最后发生断裂事故。在省煤器导淋箱底部加装一个排凝导淋，且长期处在全开状态，避免冷凝液的积累。%Aiming at a quick drop of the level in donkey boiler it is confirmed through the analysis that a stress break of the drain on economizer low-point eductor has caused a leakage.As the economizer drain is for a long time placed in an acidic condensate and b
