流动态可燃气体爆炸极限的试验研究
|
摘要
利用自行建立的可燃气体动态爆炸特性试验装置,通过试验研究了甲烷、液化石油气(含杂质)和氢气的动态爆炸极限.测试数据表明,甲烷的动态爆炸上限为5.25%,动态爆炸下限为17.05%;液化石油气(含杂质)的动态爆炸上限为2.55%,动态爆炸下限为12.85%;氢气的动态爆炸上限为4.35%,动态爆炸下限为76.05%.通过比较发现这3种可燃气体在动态条件下的爆炸下限值比静态时的爆炸下限高,动态条件下的爆炸上限值比静态时的爆炸上限低,说明动态条件下的爆炸极限范围比静态爆炸极限范围小.
In order to study the dynamic explosion limit of combustible gas,a set of test device was built.The dynamic explosion limit of methane,liquefied petroleum gas(contain impurity)and hydrogen were tested.The results show that the dynamic explosion limit of methane is 5.25%～17.05%,the dynamic explosion limit of liquefied petroleum gas(contain impurity)is 2.55%～12.85%,the dynamic explosion limit of hydrogen is 4.35%～76.05%.The dynamic lower explosion limits of three kinds of combustible gas are higher than the lower static explosion limits,the dynamic upper explosion limits are lower than the upper static explosion limits,and dynamic explosion limit range is smaller than static explosion limit range.
