摘　　要：对可能引起汽包失效的各个因素进行了系统的分析,建立了以汽包失效为顶事件的故障树。通过求出故障树的各阶最小割集以及各个基本事件的概率重要度,确定汽包主要的失效影响因素,并提出相应的解决措施。The factors resulting in the boiler drum failure were systemically analyzed,and the fault tree which taking drum failure as top event was built.Through calculating each order’s minimum cut sets of the fault tree and each basic event’s probability importance degree,the influence factors for the drum failure were determined,including the solutions to them.

关 键 词：锅炉汽包 故障树 可靠性 最小割集 概率重要度
