Multi - channel coal burner end structure from outside to inside respectively, axial flow fan, wind, coal cyclone, central air, and a gun channel. The front duct using heat-resistant steel, the rear part can be configured castable. The burner can burn inferior coal, low volatile coal, anthracite, strong adaptability to the fuel. (1) online adjustment is flexible and convenient, can according to different requirements, adjust the flame length, thickness, strength at any time; (2) the flame shape is more regular, stable, conducive to the long-term safe use of kiln lining; (3) to adapt to a variety of coal, the inferior coal, low volatile coal, anthracite can be used; (4) high combustion efficiency, reduce the formation of NO, reducing harmful emissions, environmental protection. Multi - channel coal burner is composed of nozzle, pipe, metal corrugated compensator, valves, pressure measuring instrument. Pulverized coal by the fan into the kiln, the expansion of the central air duct to adjust the flame thickness, swirling wind to rotate a certain direction scattered coal, the coal atomization and combustion. The wind is DC wind, the fire is divergent, achieve the ideal shape of flame. In addition to coal as a separate source channel, the channel is the primary air control valve can be used according to requirements, deployment.
