| 摘 要： | 实验研究纯氧环境中CO2对甲烷爆炸极限的影响.结果发现,CO2体积分数达到78%时,混和气体退出可爆范围,临界O2体积分数为14%.使用爆炸三角形分析得出CO2对甲烷爆炸具有抑制作用,且其抑爆效果好于N2;同时分析了CO2抑爆的原因,为可燃气体抑爆措施的制定提供参考.

| Abstract: | By experiment,the paper studied effect of CO2 on methane explosive limit.When CO2 content achieves 78%,the flammable mixture could not be lit,and the critical concentration of O2 is 14%.The results show that CO2 has better suppression effect on methane explosion than N2.And analyzed suppression mechanism,which is of theoretical value for guiding the application of measure in suppression combustible gas explosion in practice. |
