摘要： A process for the suspension smelting of sulfide concentrates by causing a suspension flowing downwards in a suspension reaction zone to impinge against the surface of a melt below the suspension reaction zone in order to unload the solid and molten particles of the suspension into the melt and by causing the gases to flow further in the suspension reaction zone countercurrently in relation to the suspension in order to discharge the gases from the upper section of the suspension reaction zone, in which sulfide concentrate and oxygen or oxygen-enriched air are fed into the suspension reaction zone symmetrically and in the form of so dense a suspension spray that the iron oxide of the high-temperature suspension is in a molten state and absorbs the free oxygen present in the suspension before the suspension, at a temperature of at least 1400.degree. C., unloads into the melt, the heat is recovered indirectly in the suspension reaction zone from the gases rising symmetrically and smoothly around the suspension, and the melt is fed from the suspension reaction zone into a separate melt reaction space.

摘要： A method for forming a directional and controlled suspension spray of a pulverous material and a reaction gas is intended for use in metallurgical processes and plants. In flash smelting, reaction gases are fed into a cylindrical vertical reaction chamber centrally through the top of the reaction chamber. The blasting in is via a specific blast-in member, into which the gases are usually directed horizontally for reasons of space use. This results in that the flow in the reaction chamber is asymmetrical. This disadvantage can be eliminated by means of a method according to the present invention. In the method according to the invention a pulverous material is directed into the reaction chamber mixed with a primary dispersion gas, a reaction gas directed into the reaction chamber in at least three separate, at least partly turbulent jets symmetrically around the flow of the pulverous material, and the reaction gas jets are caused in the reaction chamber to discharge into the flow of the pre-dispersed pulverous material in order to produce a turbulent but controlled suspension spray.

摘要： A device for blowing gas and a finely-divided solid into a metallurgical melt is disclosed, the device having a blast pipe which has at one end an inlet connected to a gas source and at the opposite end an outlet immersed below the melt surface in order to blow the gas into the melt. A cooling device surrounds the blast pipe, the cooling device having, at that end which is near the blast-pipe inlet, inlets and outlets for the cooling medium, and a mantle of ceramic material which surrounds at least the lower part of the cooling device. In the outlet of the blast pipe there is a Laval nozzle which is at an angle to the blast pipe and extends through the thermally insulating mantle. The cooling device further consists of smaller-diameter cooling pipes parallel to the blast pipe, the inlets of the cooling pipes being intended to be connected to a source of a gas-liquid mixture which vaporizes rapidly in the cooling device, and the mantle is surrounded by a graphite or silicon carbide sleeve, which is at least so thick that it protects the ceramic material when the device is lowered into the melt, so that the ceramic material reaches the temperature of the melt more slowly than the sleeve does and sinters before the sleeve wears out.

摘要： A suspension of a powdery substance and a reaction gas is formed by allowing the powdery substance to fall as an annular flow into a reaction space, feeding the reaction gas downwardly to encircle the annular flow of powdery substance, the kinetic energy of the annular flow of descending powdery substance being utilized towards its gradual spreading to the sides with the aid of a sliding surface disposed within the reaction space, so that the flow of powdery substance which has been spread to be laterally directed will meet the reaction gas flow substantially at right angles in the reaction space.

摘要： The invention relates to a boiler construction successive to a smelting furnace, particularly a flash smelting furnace, whereby a direct flow from the radiation section of a waste heat boiler to the convection section thereof is prevented by means of an intermediate plate located in the boiler, advantageously made of cooler pipes and arranged in a direction essentially parallel to the flow. At the same time, the return of the gas flow to the outlet opening of the smelting furnace is prevented in order to reduce the tendency to dust accretions caused by the gases. By means of a flow pattern thus optimized, the eddy currents or dead areas in the radiation section are remarkably reduced, which lengthens the delay time advantageous mainly for heat transfer.

摘要： A method for oxidizing the pulverous fuel of a furnace, advantageously a flash smelting furnace, by means of a burner, so that the oxidation takes place mainly owing to an effective mixing of two different combustion gases, pulverous fuel and possibly an extra fuel, in the furnace space. The combustion gases are conducted into the furnace space in separate jet flows, so that oxygen is fed in through the center in an at least partly turbulent flow, and the air is fed around it in several separate flows. A burner for mixing pulverous fuel and combustion gas and for burning them in the furnace space is described.
