高炉的休风,要求操作人员特别注意并准确执行制定的规则。这是因为高炉煤气与空气相混合可能生成爆炸性混合体,这种混合体一经着火,便发生爆炸。高炉煤气之所以会生成爆炸性混合体,是因为煤气中既有一氧化碳,又有氢。虽然焦炭高炉的煤气中,氢的含量并不大(通常是2—3％,只在有水经常落进炉缸时,才增高一些),但是这一点含量即能大大地增高煤气的爆炸性能。煤气爆炸时,煤气中可燃成份突然燃烧;结果,煤气的温度和体积剧烈增加,因而压力迅速高涨并发
Blast off, requiring the operator to pay special attention to and accurately implement the rules. This is because the mixture of blast furnace gas and air may generate explosive mixtures that explode upon ignition. The reason why blast furnace gas will generate explosive mixtures, because the gas has both carbon monoxide and hydrogen. Although coke blast furnace gas, the hydrogen content is not large (usually 2-3%, only in the water often fall into the hearth, only a few higher), but this point that can greatly increase the gas explosion performance . When the gas explodes, the flammable components in the gas suddenly burn; as a result, the temperature and volume of the gas increase dramatically, so the pressure rapidly rises and goes high
