【摘要】 最小点火能是粉尘爆炸的重要参数,对衡量粉尘爆炸的危险性起到重要作用,开展此类研究意义重大。分别对不同浓度小麦淀粉、香精粉、铝粉和2,4,6-三硝基甲苯(TNT)粉的最小点火能进行测定和分析。结果表明:对于粉尘爆炸而言,粉尘浓度是最小点火能的极值因素;即粉尘存在一个浓度,使得最小点火能最小。四类粉尘最小点火能的大小关系为:TNT粉<香精粉<铝粉<小麦淀粉。更多还原

【Abstract】 The minimum ignition energy is a significant parameters and plays an important role indust explosion.So it is very useful to study for us.Minimum ignition energy of wheat starch,flavor dust,aluminum dust,2,4,6-Trinitrotoluene(TNT) dust were measured and discussed in differentconcentration.The results show that:The dust concentration is an extreme factor of the minimum ignition energy in dust explosion.In other words,there is a concentration,and it makes the value of minimum ignition energy minimum.The relationship between four kinds of dust is:TNT dust <flavor dus<aluminum dust<wheat starch.更多还原
