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.
Coal mill dust collectors have a substantial effect on productivity, yet have received relatively little attention as companies implement cost-saving programs, like the use of petcoke as a fuel reduction measure. Petcoke is typically ground finer than coal, and it has a particularly sticky nature that makes it more difficult to clean from ...
