二甲醚、甲烷及二甲醚／甲烷混合物的爆炸极限实验研究

THE EXPLOSION LIMIT OF DIMETHYL ETHER,METHANE AND THEIR MIXTURES

本文对二甲醚、甲烷及不同体积比例下二甲醚和甲烷混合物,在室温至80℃温度区间、绝对压力区间0.1～0.3 MPa的爆炸极限进行了实验研究。并通过实验数据分析了温度、压力对可燃性气体爆炸极限的影响,同时通过实验测量数据验证了几种常用爆炸极限推算方法的准确性。

The explosion limits of dimethyl ether, methane and different mixtures of dimethyl ether and methane were measured under the temperature ranging from room temperature to 80℃ and the pressure ranging from 0.1 to 0.3 MPa. In addition, the effects of temperature and pressure on the explosion limit were analyzed, and the accuracies of some theoretical calculation models of explosion limit were tested with the experimental results.
