粉尘为何会爆炸呢?悬浮在空气中颗粒很细的可燃粉尘表面积大,被氧化的加氢系统,一旦遇火燃烧,会发生剧烈的氧化反应,同时产生大量的热和很高的压力,形成爆炸。而且,某一点上的粉尘爆炸后,所产生的火焰和高温,作为新的火源,又引爆另一点上的粉尘,或者由于爆炸冲击,大量的粉尘被吹扬起来,迅速形成新的爆炸混合物,在火焰和高温作用下,再次发生爆炸。粉尘爆炸所具备的三个条件是:一是粉尘微小到能够悬浮在空中,堆积在一起的粉尘不会爆炸;二是粉尘与空气混合达到一定浓度;三是有火源,即使是极微弱
Why does the dust explode? The surface area of the combustible dust suspended in the air is very fine particles, oxidized hydrogenation system, in case of fire burning, will occur violent oxidation reaction, while generating a lot of heat and high pressure, the formation of explosion. Moreover, after a certain point of dust explosion, the resulting flame and heat, as a new source of ignition, detonate another point of dust, or due to the impact of the explosion, a lot of dust is blowing up quickly to form a new explosive mixture , In the flame and high temperature, the explosion again. Dust explosion with the three conditions are: First, the tiny dust to be suspended in the air, the accumulation of dust will not explode; Second, the dust mixed with air to a certain concentration; Third, there is a source of fire, even if it is very weak
