摘要：A flash smelting furnace includes a reaction shaft defining a reaction chamber therein, a plurality of reaction air blowing pipes passing through the side wall of the reaction shaft for blowing reaction air into the reaction chamber, and at least one concentrate burner attached to the top end of the reaction shaft and comprising a concentrate chute, a tubular auxiliary fuel burner extending vertically through the chute, a tubular oxygen blowing pipe concentrically surrounding the auxiliary fuel burner and a dispersion cone attached to the lower end of the oxygen blowing pipe. The air from the blowing pipes disturbs the jet stream of mixed smelting material and reaction gas in the reaction chamber, thereby achieving a uniform mixture of the material and the reaction air and extending the retention time of the material in the reaction shaft.
