    Coal Volatility Explosion frequency increases with an increase in volatility content but this trend is as weak statistically as the other categories. Coal Moisture Explosion frequency remains unchanged with increasing coal moisture. Overall there is a connection between moisture and pulverizer age. The newer units have a trend toward using 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 dust will
