【摘要】：为评估甲醇汽油燃爆危险特性,补充完善甲醇汽油的技术指标,采用FRTA爆炸极限测试仪测试研究不同组成甲醇汽油混合物的爆炸下限,并分析甲醇体积分数、初始温度对甲醇汽油爆炸下限的影响。结果表明:甲醇汽油混合物的爆炸下限随甲醇体积分数的增大而升高,从M0的1.129%升高到M100的6.523%;随着初始温度从25℃升高至100℃,M50,M85甲醇汽油的爆炸下限均呈下降趋势,且甲醇体积分数越大,下降趋势越明显,但是M15甲醇汽油混合物的爆炸下限受温度的影响却很小;不同的样品计量方式,会导致不同的爆炸极限测试结果,一般采用样品分压计量,测得的爆炸极限更准确;采用样品体积计量,测得的爆炸上下限均偏高。
[Abstract]:In order to evaluate the explosion hazard characteristics of methanol gasoline and to supplement the technical specifications of methanol gasoline, the explosion limit of different components of methanol gasoline mixture was measured by FRTA explosion limit tester, and the methanol volume fraction was analyzed. The effect of initial temperature on the lower limit of methanol gasoline explosion. The results show that the lower explosive limit of methanol gasoline mixture increases with the increase of methanol volume fraction, from 1.129% of M0 to 6.523% of M100, and decreases with the increase of initial temperature from 25 鈩，
