    In a pulverized coal system, the coal is pulverized in a mill to the consistency of talcum powder. The pulverized coal is then entrained in primary air before being fed through the burners to the combustion chamber, where it burns in suspension. Pulverized coal furnaces are classified as either dry or wet bottom, depending on the ash removal technique
