Pulverizers system provides pulverized coal to the boiler. Within the pulverizers, the coal is ground and classified to the proper size. Primary air is used to dry and transport the pulverized coal for burning in the boiler [1]. There are various issues related to pulverizer performance such as poor coal fineness and uneven coal flow distribution.
