摘　　要：以氮气为例系统地研究了惰性气体对焦炉煤气的爆炸极限的抑制机理,并进行了相关的理论探讨,结果表明,在整个爆炸极限范围内,最大允许氧含量和爆炸极限具有一一对应的关系,惰性气体对两者具有相似的影响,惰性气体能大大缩小焦炉煤气爆炸极限范围和最大允许氧含量范围,甚至使其退出可爆范围,大大降低其燃烧爆炸的危险性.运用爆炸极限和最大允许氧含量的理论关系,得到了两者互推的关系式.Nitrogen gas was taken as an example, the suppression mechanisms of inert gas on the explosion limit of coke oven gas were systematically researched. It is found that the maximum allowable oxygen content and the explosion limit have a one-to-one relationship. Inert gas has a similar effect on both of them, which can dramatically nar- row the explosion limit range and the maximum allowable oxygen content range of coke oven gas, and even suppress coke oven gas explosion, thus greatly reducing the explosion risk. According to the relationship between explosion limit and maximum allowed oxygen content, the formulae of referring from each other are also derived.

关 键 词：爆炸极限 焦炉煤气 最大允许氧含量 惰性气体 抑制
