However, this small explosion isn't the problem. The problem is what happens next. If there's dust in the area, the primary explosion will cause that dust to become airborne. Then, the dust cloud itself can ignite, causing a secondary explosion that can be many times the size and severity of the primary explosion.

The coal mill is operated as an air-swept mill and "blows" directly into the combustion zone of the steam boiler, via a pipeline connection. In case of an explosion, normally as consequence of ignition within the mill chamber, there will be explosion propagation towards the boiler. The combustion "cloud" will propagate to where it finds ...
