Cause of gas explosion

In the gas production and use system, hot fuel, red-hot furnace wall, electrical equipment that does not meet the explosion-proof requirements, wire short circuit, iron impact, friction, open flame for maintenance, lightning strike, static electricity, sulfur-containing spontaneous combustion, cigarette butts, etc. It may all become ignition energy.

The lower explosion limit of coke oven gas, hydrogen and benzene vapor is very low, so when the pipes, fittings or equipment are lax, such gases leaking into the air will easily explode when they meet the fire source. On the contrary, the lower explosion limits of blast furnace gas, producer gas, hydrogen and carbon monoxide are relatively high. When the pipeline and equipment are lax and negative pressure occurs, it is easy to inhale air to form explosive combustible mixture. In addition, when the gas pressure in the heating gas pipeline system is too low and the flow rate is too small, it is easy to cause the same fire and explosion, which should be prevented.
