Coal Pulverizer Explosions - Babcock Power

Units firing bituminous coals fired units show a slight decrease in explosion frequency with increasing number of pulverizers per unit. However, subbituminous fired units show a sharp increase in explosion frequency with increasing number of pulverizers per unit. Pulverizer Age: Explosion frequency appears to be independent of pulverizer age.
