Coal Mill - an overview | ScienceDirect Topics
Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throat’s flow-shaping contour, enables recirculation patterns that …
Classification performance of model coal mill classifiers ...
Introduction The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles. Thus, the classification performance will influence the ignition, burning, and burnout of the coal particle, and NOx formation in the furnace as well [1-4].
