- The explosiveness of four kinds of coal has been determined by testing two parameters,the lower explosion limit and the length of return fire. 为此,探讨了煤粉预热喷吹对混合煤粉爆炸性的影响,以期为强化喷煤燃烧提供一种新的有效工艺方法。
- Using this system, lower explosion limits of methane mixing respectively with Hydrogen, Isobutane and normal hexane were determined. 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。
- And when concentration of isobutane and normal hexane come to about 0.25%, methane's lower explosion limits are about 2%. 当异丁烷和正己烷的体积分数约为0.;25%25时，甲烷的爆炸下限可降到2%25左右。
- The maximum duration time is coincided with the lower explosible limit made by IEC standard. 对于不同的粉尘,通过燃烧时间来判断爆炸下限对于工业粉尘防爆设计具有实际意义。
- Flammable gas as defined by the DOT is any compressed gas that either forms a flammable mixture with air at a concentration of less than 13% by volume, or has a flammable range in air wider than 12%, regardless of the lower explosive limit (LEL). DOT对易燃气体的定义是：在体积浓度小于13%25的情况下同空气形成易燃混合物的任何压缩气体，或者不考虑较低的爆炸极限（LEL），在空气中的易燃范围大于12%25的任何压缩气体。
