  • Reduced Unit Capacity

    Bowl differential on pulverizers of this size normally range between 7 to 10 inches w.g. at full load. In some cases bowl differential is as high as 12” w.g. due to coal grindability andor moisture. Lower coal grindability (harder coal) or higher moisture content will result in higher circulation rates between the classifier and grinding zone.Pulverizer Fire and Explosions,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. Mill puffs most often originate in the under bowl area and can cause very destructive damage to the primary air ducting.
