煤或其他含碳物质在氧气不足的情况下燃烧,会产生一种不安定的混合性气体,主要含氢、甲烷、乙烯、丁烯、碳化氢、一氧化碳等。其中一氧化碳含量最高,对人的毒性大,平常说的煤气中毒,就是指一氧化碳(CC))对人体造成的毒性损害。一氧化碳是无色、无臭的气体,比空气轻。居室、矿井、巷道等处都可能发生煤气中毒,但一般以在居室里生煤炉取暖临睡 Combustion of coal or other carbonaceous materials in the presence of insufficient oxygen produces an unstable gas mixture containing mainly hydrogen, methane, ethylene, butylene, hydrocarbon, carbon monoxide and the like. One of the highest carbon monoxide, toxic to humans, the usual gas poisoning, refers to carbon monoxide (CC) on the human body caused by toxic damage. Carbon monoxide is a colorless, odorless gas that is lighter than air. Gas poisoning may occur in living rooms, mines, roadways, etc., but it is generally used to warm and sleep in a coal stove in a living room
