swelling of liquid

With the progress of equipment material aging and in case of abnormal operation the cracks will rapidly expand,leading in extreme circumstances to boiling liquid expanding-vapor explosion(BLEVE).

在锅炉运行中,由于各种原因使得在锅筒主体上形成细小裂缝,一旦出现设备材料的老化和故障运行工况,导致裂缝快速扩展,就有可能出现沸腾液体膨胀蒸汽爆炸(BLEVE)的极端情况。

BLEVE is a kind of disaster that its consequences are very serious,to analyze the accident characteristics of both the external environment and the internal cause is the basic to prevent,control and research this accident.

沸腾液体膨胀蒸气爆炸(BLEVE)做为事故后果极为严重的一种灾害类型,从事故发生的外在环境和内在致因角度开展事故特性分析,是进一步研究事故预防控制手段的基础。
