煤气是多种可燃气体组成的混合气体,具有易燃易爆的特点,它的成份,主要是氢气、一氧化碳和轻烃类,着火点一般都在500—600℃.当与空气混合成一定比例后,遇明火都会爆炸.那么,煤气炉一般在什么情形下能引起爆炸呢?我们知道,煤气正常燃烧,要有燃烧器.如家用煤气灶,蓝色火焰从燃烧器火孔喷出来,燃烧很稳定.工业用煤气,为了集中热量,需要一个炉 Gas is a mixture of a variety of combustible gases, with flammable and explosive characteristics, its composition, mainly hydrogen, carbon monoxide and light hydrocarbons, fire points are generally 500-600 ° C. When mixed with air into a certain proportion , In the event of a fire will explode. So, under what circumstances the gas stove can usually cause an explosion? We know that the normal gas combustion, there must be a burner, such as domestic gas stove, the blue flame is emitted from the burner hole, the combustion is very Stable. Industrial gas, in order to focus on heat, requires a furnace
