Pulverizer Fire and Explosions

Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill “puffs”. 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.

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

a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the air. Even when a mill is shut down routinely, there is a danger that any residual coal left within the mill will oxidise, which can explode as the mill is restarted. To prevent a coal fire, the mills
