Coal Petcoke Mill Explosion

Explosion protection for coal grinding plants. What should ...

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 ...

Fire and Explosion Prevention in Coal Pulverizing Systems

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal
