摘要
在20L爆炸球中,通过化学点火,在不同喷雾压力条件下对比煤基柴油与-10号军用柴油和-35号军用柴油云雾的燃爆特性.采用液体燃料持续燃烧性能测定仪测试燃料的燃烧性能,分析不同温度下燃料的燃烧情况.结果表明,随着喷雾压力的升高,三种柴油的最大爆炸压力和最大爆炸温度都有上升的趋势,在同一喷雾压力条件下,煤基柴油的最大爆炸压力和温度大于-10号军用柴油和-35号军用柴油的最大爆炸压力和温度.无约束条件下煤基柴油的燃烧性能一定程度上要优于-10号军用柴油和-35号军用柴油的燃烧性能.实验获得了三种柴油不同实验条件下的燃爆参数,并进行了定量评价.
In standard 20 L explosion sphere vessels, using chemical ignition, comparative study on combustion and explosion characteristics of coal-based diesel, military diesel -10 and military diesel -35 was performed. Using continued burning performance analyzer, the combustion performance of diesel was tested, and the burning performance at different temperatures was analyzed. The results show that the maximum explosion pressure and maximum temperature have a rising trend with the spray pressure increase. The maximum explosion pressure and maximum temperature of the coal-based diesel are bigger than that of military diesel -10 and military diesel -35. In unconstrained condition, the burning performance of the coal-based diesel is better than that of military diesel -10 and military diesel -35 to some extent. The experiments obtained the combustion and explosion parameters of the three kinds of diesel under different experimental conditions and carried out quantitative evaluated.
