As shown in FIG. 3, the conventional concentrate burner 10 comprises a concentrate shot 1, a reaction gas feed pipe 2,
A burner cone 3 and a fixed or movable wind speed adjuster 4 are provided. The concentrate shot 1 is a tubular member for feeding a smelting raw material, and extends vertically toward a reaction tower 11 (see FIG. 1). The reaction gas feed pipe 2 is formed such that its diameter becomes smaller as it goes below a predetermined position in the pipe. The burner cone 3 is formed in a tubular shape, and the upper end 3a is connected to the lower end 2a of the reaction gas feed pipe so that the concentrate stream and the reaction gas stream are fed into the reaction tower 11. The wind speed adjuster 4 is formed in such a shape that the width of the flow path of the reaction gas formed by the reaction gas feed pipe 2 and the concentrate shot 1 is reduced to a predetermined size. Is provided on the outer periphery of the reaction gas, so that the velocity of the reaction gas flow can be determined. An auxiliary fuel burner 5 for raising the temperature of the reaction gas fed through the reaction gas feed pipe 2 extends toward the reaction tower 11 at the center of the concentrate shot 1.

[0006] When using a solid fuel such as pulverized coal as an auxiliary fuel, the concentrate burner 10 may not include the auxiliary fuel burner 5. At the tip of the auxiliary fuel burner 5, a dispersion cone 6 is provided at a position where the smelting raw material sent vertically from the concentrate 1 collides with the smelting raw material. To make it easier to come into contact with the reaction gas, thereby preventing the generation of so-called heaps (lumps of unmelted material).

In such a concentrate burner, when a solid sulfide smelting raw material is charged from the concentrate shot 1 on the outer periphery of the auxiliary fuel burner 5, the reaction gas further reacts on the outer periphery thereof. It is blown from the feed pipe 2. After the solid sulfide smelting raw material exits from the concentrate shot 1, the solid sulfide smelting raw material comes into contact with the reaction gas flow adjusted to a predetermined speed via the wind speed regulator 4, and the heat of the auxiliary fuel or the reaction gas is detected. The reaction proceeds when the temperature is increased by heat or radiant heat from the inner wall of the furnace.

However, in the above-mentioned conventional concentrate burner 10, since the reaction gas adheres to the inner wall of the burner cone 3 and flows, it is difficult to flow toward the inside of the burner cone 3. For this reason, of the smelting raw materials discharged into the burner cone 3 from the concentrate shot 1, those flowing outside easily come into contact with the reaction gas, while those flowing inside have few chances to come into contact with the reaction gas. The reaction was difficult to proceed. In particular, when the supply amount of the smelting raw material is increased, this tendency becomes remarkable, the position in the reaction tower at which the desired desulfurization rate is reached is lowered, and the combustion is rapidly performed within a limited range in the lower part of the reaction tower 11 in the vertical direction. Therefore, the heat load on the inner wall brick of the reaction tower 11 increases, and the damage on the inner wall brick of the reaction tower becomes severe. In addition, problems such as deterioration of separability between mat and slag and magnetite trouble due to increase in magnetite concentration in slag also occur.
