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. Swirled air, coupled with the burner throat’s flow-shaping contour, enables recirculation patterns that extend into the furnace. Burners are typically located on the front wall or both the front and rear walls, which is typically referred to as opposed firing
