    Pulverizer control system The Babcock amp; Wilcox Company

    This inventive control system provides improved pulverizer response by controlling fuel flow into the furnace rather than into the pulverizers. Improved response is also obtained since the proper amount of overunder feeding is controlled to effect faster changes in the mill storage level of the pulverizer.
