摘　　要：CNG气瓶是CNG加气站中常用的一种储气装置,它作为一种高压储气容器,如果失效将会产生重大的危害后果。文中对其泄漏后产生的爆炸后果进行了分析,对比了蒸气云爆炸(VCE)定量评价模型和API pub 581定量后果评价模型,并在分析过程中结合某气瓶组的实例,对两种评价模型所得到的爆炸后果进行了比较。CNG cylinder is a sort of used storage device in CNG filling stations. As a sort of high - pressure gas storage container, it will lead to the badly harm consequences if it is failure. The explosion consequences after its leakage are analyzed in this article, it compares the vapor cloud explosion （VCE） quantitative evaluation model and API pub 581 consequences evaluation model. The consequences of the explosion with two evaluation models are compared according to a example with a set of CNG cylinders in analytic process.
