explosion limit

The explosiveness of four kinds of coal has been determined by testing two parameters, the lower explosion limit and the length of return fire.

该试验通过测定爆炸下限与返回火焰长度这两个参数来确定4种煤粉的爆炸性。

Indoor gas pipe systems leak, leakage of gas to reach the explosive limit encounter an ignition source, fire explosion, according to the statistics of industrial accidents in recent years, indoor gas leakage accident most of them are caused by the gas pipeline hose off.

室内燃气管道系统泄漏后，泄漏燃气达到爆炸极限遇到点火源即会发生火灾爆炸事故，根据近年来的事故统计分析，室内燃气泄漏事故大部分都是由燃气胶管脱落造成的。

In the thermal explosion balanced method, mix dust explosion limit prediction model had been studied.

通过热爆炸平衡判断方法，研究得出混合粉尘的爆炸极限的预测模型。
