  • Coal-Fired Industrial Boiler Inspection Guide

    Most pulverized-coal-fired boilers have at least one extra pulverizer to allow routine maintenance to be performed without reducing the boiler load. Selection of the number of pulverizers needed to handle the desired load is based on the heat content and grindability of the coal because these charac- teristics affect pulverizer capacity.
