近年来,水泥立窑厂塌窑事故时有发生,表现为窑内物料骤然下沉,大量红火球块及碎粉料从看火操作门喷出,造成人身伤亡事故。这实际上是出于立窑内一氧化碳爆炸引起的。一氧化碳爆炸浓度范围是16.3％～71.2％,如果含有粉尘和水蒸气,其爆炸浓度范围还将扩大。据资料报道,在一氧化碳与氧的混合物中,当各自浓度均高于16.2％,并大致成1∶1的比例时,只要一接触火就可以燃烧,引起爆炸。引起立窑一氧化碳爆炸的原因大致是:
In recent years, cement kiln plant collapse kiln accidents occur from time to time, the performance of the sudden sinking of materials in the kiln, a large number of red fireballs and broken pieces of powder discharged from the fire operating door, resulting in personal injury. This is actually caused by a carbon monoxide explosion in the shaft kiln. Carbon monoxide explodes in the concentration range of 16.3% ~ 71.2%, if the dust and water vapor, the explosion range of concentration will also be expanded. According to the information reported, in the mixture of carbon monoxide and oxygen, when the concentration of each is higher than 16.2%, and roughly the ratio of 1: 1, it can burn as soon as it contacts the fire and cause an explosion. The cause of the shaft kiln carbon monoxide explosion is roughly:
