| 摘要 | PURPOSE: To accelerate concentrate reaction according to operating conditions by blowing a gas for reaction at the same angle from blasting nozzles disposed to face each other freely turnably near the central part of the side wall of a reaction column provided with a concentrate burner in the top part. CONSTITUTION: The melt formed by blowing raw materials for refining and the preheated gas for reaction, such as air, from the concentrate burner 2 in the peak part of the reaction column 3 to effect reaction is stored into a settler 6 provided successively in the lower part. One or more sets of the blasting nozzles 19 are disposed in the positions line symmetrical with a perpendicular line 18 running the central point 17 of the reaction column in the side wall near the central part of the side wall of the reaction column 3 in the above-mentioned flash smelting furnace. The blast axis direction of the nozzles 19 are set respectively in the above-mentioned perpendicular line 18 direction and are constructed turnable within the perpendicular plane around the mounting positions. The gas for reaction is partly blown at a prescribed rate from the above-mentioned blasting nozzles 19 at the time of refining sulfide ore, etc., in this flash smelting furnace. Further, the gas is so blasted that the blasting direction is upper than lower 45° of the horizontal plane and the blasting directions from one set of the blasting nozzles 19 are of the same angle.
