Pulverised Fuel an overview ScienceDirect Topics

In wall firing, the fuel is mixed with combustion air in individual burners. 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
