煤气-空气多元爆炸性混合气体爆炸反应极限范围的研究

Study of limiting range of explosive reaction for polybasic explosive mixed gas in coalgas-air

通过大量实验对煤气-空气等多元爆炸性混合气体的爆炸极限范围进行了研究,找出了影响爆炸范围的主要因素。实验表明:爆炸反应呈阶段性和不完全性;甲烷对爆炸范围有影响;水气含量对支链反应有阻止作用;一氧化碳对支链反应有一定的贡献。本文结论对科学的制定安全指标提供了理论依据。

In present paper, limiting range of explosive reaction for polybasic explosive mixed gasin coal gas and air have been carefully studied by a large number of experiments. The main factors which affects explosive range have been found out. The results show: explosive reaction have presented the character of stage and uncomplication; methane have affected the range of explosion; contents of vapour have contributed something to the branched chain reaction. The results of this paper have provided scientific theoretical foundation for drawing up safety targets.
