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 flowshaping contour, enables recirculation patterns that .
However, when the momentum is too large, it may mean that the wind volume of the primary wind is large, which is not conducive to the thermal efficiency. The burner momentum can be visually evaluated by the reflux of the flue gas, that is, moderate flue gas recirculation means that the pulverized coal and air are well mixed.
