Abstract:
     This invention provides an atomizer burner for gasifying pulverized coal and relevant technology. The atomizer burnerconsists of a cyclonic nozzle for primary air, jet orifice for tangent entering of secondary air, cyclonic pre-burning chamber, cyclonic duster, chamber for full combustion of ashed carbon, jet orifice for entiring of tertiary air for full combustion, cyclonic regulator for guarternary air, locking hopper for removing ash residues, and ascending tube. Puverized coal is preburned and gasified in cyclonic preburning chamber and then passes through cyclonic duster to remove dust, clean hot coal gas is thus obtained. The carbon remained in ashes is reburned in chamber for full combustion, the ashes are removed as solid residues.
