Pulverized Coal Explosions in the U.S. Utility Industry

Coal Type: The subbituminous coals have explosion frequencies of about twice those of bituminous coals. The explosion values of lignite coals were ignored due to the extremely small population. Coal Volatility: Explosion frequency increases with an increase in volatility content, but this trend is as weak statistically as the others.

Pulverizer Fire and Explosions

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
