The coal pulverizer is one of the most hazardous pieces of equipment from a fire and explosion viewpoint because fuel and oxygen for combustion are always present. A dust explosion is often described as a rapid burning of combustible particulate within a confined area, which results in the generation of intense heat and corresponding pressure rise.

Explosions in a pulverized coal system are normally called "puffs." A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature. Mill puffs most often originate in the under bowl area and can cause very destructive damage to …

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.
