  • How much is pulverized coal particle size important in ...

    It is certainly important, as the extent to which the coal is pulverized will factor into complete combustion. Too big and the fuel will not burn entirely, leading to a lot of wasted fuel. Coal pulverizers have classifiers that restrict the size of the coal being blown into the furnace by the primary air supply. Any coal that is considered too large to burn through entirely is restricted by the classifier and falls back down into the .
