产生一氧化碳的环境一氧化碳是无色无臭的气体,人们仅在它燃烧过程中由于发出蓝色的火焰才能看到。各种含碳物质在不完全燃烧时都可产生一氧化碳。焦炉煤气和水煤气内含有4.5～39%的一氧化碳,煤气发生炉所产生的气体也以一氧化碳为主。有些化工厂必须以一氧化碳为原料。矿井巷道内放炮后10分钟内空气中一氧化碳的浓度可达0.35毫克/升,建筑隧道时爆炸后也产生一氧化碳,在通风不良时虽然爆炸已经过2～4日,一
Carbon monoxide-producing environment Carbon monoxide is a colorless, odorless gas that people can only see during the burning process by emitting a blue flame. A variety of carbonaceous materials can produce carbon monoxide when they are not completely combusted. Coke oven gas and water gas containing 4.5 to 39% of the carbon monoxide, gas furnace gas is also produced mainly of carbon monoxide. Some chemical plants must use carbon monoxide as raw material. Concentration of carbon monoxide in the air within 10 minutes after blasting in mine tunnel can reach 0.35 mg / l, carbon monoxide also occurs after explosion in tunnel construction, although it has been 2 to 4 days since the explosion was caused by poor ventilation
