星星之火引发的爆炸在生产加工面粉的过程中,常常会产生大量极细的面粉颗粒。如果未采取有效的通风除尘措施,当这些悬浮于空中的面粉颗粒达到较高的浓度时,一旦遇有火苗、火星、电弧或适当的温度,瞬间就会燃烧起来,形成猛烈的爆炸,其威力甚至不亚于炸弹,因此面粉厂内严禁吸烟及明火作业。面粉“变身”为“炸药”的原因是多方面的。首先,面粉的成分中含有碳、氢等元素,它们均可组成可燃性物质。但事实上,面粉绝不会像火药那样一点就燃,它们发生爆炸的重要条件是要在密闭的空间内产生大量极细的面
The explosion caused by the sparks of the stars often produces large amounts of very fine flour particles in the production and processing of flour. If no effective ventilation and dust-removal measures are taken, the flour, suspended in the air, reaches a higher concentration, and once it encounters a flame, a spark, an arc or a suitable temperature will instantly burn and form a violent explosion with its power No less than bombs, so smoking and open flame operations are strictly prohibited in flour mills. Flour “turned ” to “explosives ” for many reasons. First of all, the flour contains carbon, hydrogen and other elements, which can be composed of flammable substances. But in fact, the flour will never burn like a gunpowder, the important condition of their explosion is to produce a large number of very thin noodles in a confined space
