煤尘爆炸的规律和影响因素煤尘爆炸是有条件有规律的,其爆炸规律是:飞扬在空气中一定细度、一定浓度的可爆性煤尘,遇到火就会引燃爆炸.沉积煤尘不会爆炸;飞扬的煤尘不遇火也不会爆炸,具体的说,煤尘爆炸必须具备三个条件:一、煤尘本身具有爆炸性二、煤尘在空气中呈悬浮状态(即所谓煤尘云)而且具有一定浓度,就是说,煤尘在热化之后,煤尘放出的热量必须超过散失在 The law and influencing factors of coal dust explosion Coal dust explosion is conditional and regular, its explosion law is: flying in the air a certain degree of fineness, a certain concentration of combustible coal dust, fire will ignite the explosion. In particular, coal dust explosion must have three conditions: First, the coal dust has its own explosive Second, coal dust in the air was suspended (the so-called so-called Coal dust) and have a certain concentration, that is, after the coal dust in the heating, the heat emitted by coal dust must be more than lost
