| 摘 要： | 为研究矿井瓦斯中含有的氢气及重烃组分对瓦斯爆炸下限的影响,建立了多组分瓦斯混合气体爆炸实验系统.运用该实验系统对分别混有氢气、异丁烷和正己烷的甲烷气体的爆炸下限进行了测定.实验结果表明:强点火源条件下,当混有氢气的体积分数达到1.5%时,甲烷的爆炸下限可以降到1%;当异丁烷和正己烷的体积分数约为0.25%时,甲烷的爆炸下限可降到2%左右.图8,表5,参10.

| Abstract: | In order to study the effect of hydrogen and heavy hydrocarbon on the lower explosion limits of gas. The experimental system,for the explosion of gas mixing with many ingredients,was established. Using this system,lower explosion limits of methane mixing respectively with Hydrogen,Isobutane and normal hexane were determined. And the results indicate that,with high-energy point ignition,the methane's lower explosion limits are decreased to about 1% while the Hydrogen concentration is 1.5%; And when concentration of isobutane and normal hexane come to about 0.25%,methane's lower explosion limits are about 2%. 8figs.,5tabs.,10refs. |
