Abstract： The explosion characteristics of M15 methanol-gasoline mixture was experimental test by using FRTA explosion limit instrument. The effect of temperature on the explosion area of the sample was studied. The results show that the lower explosion limit of M15 methanol-gasoline mixture is 1.716% and the upper explosion limit is 11.451% at the initial temperature of 80 ℃. The lower explosion limit of M15 methanol-gasoline is in the range of 1.711%-1.760% with the initial temperature from 25 ℃ to 100 ℃, and the upper explosion limit of the sample changes between 11.253% and 11.451%. Considering experimental error and precision, it can be approximated that the temperature has little influence on the explosion area of M15 methanol-gasoline mixture.
Key words： M15 methanol-gasoline mixture； explosion limits； vapor explosion； gas explosion

摘要:利用FRTA爆炸极限仪测定了M15甲醇-汽油混合物的爆炸特性。 通过试验研究了温度对M15甲醇-汽油混合物爆炸范围的影响。 研究结果表明， 在初始温度为80 ℃时， M15甲醇-汽油混合物的爆炸下限为1.716%， 爆炸上限为11.451%。 当温度变化范围为25 ℃-100 ℃时， M15甲醇-汽油混合物的爆炸下限范围为1.711%-1.760%， 爆炸上限的范围为11.253%-11.451%。 基于合理的试验误差可知， 温度对M15甲醇-汽油混合物的爆炸范围影响较小。
