    METHOD FOR CONTROL OF THE THERMAL BALANCE OF THE REACTION CUBE OF A SUSPENSION MATERIAL FUSION OVEN AND CONCENTRATED MATERIAL BURNER
    Background of the Invention [001] The present invention aims at a method of controlling the thermal balance of a reaction vessel of a suspension melting furnace.
    [002] Another objective of the invention is to provide a concentrated material burner to feed a reaction gas and powdery solid matter to the reaction vessel of the suspended material melting furnace.
    [003] The invention relates to the method that takes place in a suspension melting furnace, such as a flash melting furnace, and to a concentrated material burner to feed reaction gas and powdery solid matter to the reaction vessel of the melting furnace of suspended material, such as the flash melting furnace.
    [004] The flash melting furnace comprises three main parts: a reaction vessel, a lower oven and a rising collector. In the flash smelting process, the powdery solid material comprising a sulfidic concentrate, a slag-forming agent and other powdered components, is mixed with the reaction gas through a concentrated material burner, disposed on the top of the reaction vessel . The reaction gas can be air, oxygen or oxygen-enriched air. The concentrated material burner normally comprises a feed tube to feed powdery solid matter to the reaction tank, where the orifice of the feed tube opens to the reaction tank. The concentrated material burner normally also comprises a dispersion device, arranged concentrically inside the feed tube, extending a distance from the orifices of the
    Petition 870170089586, of 11/21/2017, p. 8/35
    2/16 feed tube, inside the reaction tank and comprising dispersion gas openings, to direct a dispersion gas to the powdery solid material that circulates around the dispersion device. The concentrated material burner usually also comprises a gas supply device for feeding reaction gas to the reaction vessel, the gas supply device opening to the reaction vessel through an annular discharge orifice that surrounds concentrically the feed tube, for mixing the reaction gas, which is discharged from the annular discharge orifice, with powdery solid matter, which is discharged from the half of the feed tube and which is directed laterally by means of the dispersion gas. The flash smelting process comprises a stage in which the powdery solid matter is fed to the reaction vessel through the orifice of the concentrated material burner feed tube. The flash smelting process comprises a stage in which the dispersion gas is fed to the reaction vessel through the dispersion gas orifices of the dispersion device of the concentrated material burner, to direct the dispersion gas to the surrounding powdery solid matter. the dispersion device, and a stage in which the reaction gas is fed to the reaction vessel, through the annular discharge port of the gas supply device of the concentrated material burner, for mixing the reaction gas with the solid matter, which is discharged in the middle of the feed tube and which is directed laterally by means of the dispersion gas.
    [005] In most cases, the energy required for the fusion is obtained from the mixture itself, when the components of the mixture that are fed to the reaction vessel, the powdery solid matter and the reaction gas,
    Petition 870170089586, of 11/21/2017, p. 9/35
    3/16 react to each other. However, there are raw materials that do not produce enough energy when they react with each other, and that for a complete fusion require that the combustible gas also be fed to the reaction vessel, to produce energy for the fusion.
    [006] Currently, there are several known alternatives for correcting the thermal balance of the reaction vessel of a suspended material melting furnace, that is, raising the temperature of the reaction vessel of the suspended material melting furnace to avoid cooling the reaction vessel of the suspended material melting furnace. There are not many ways of correcting downward thermal balance of the reaction vessel of the suspended material melting furnace, ie, reducing the temperature of the reaction vessel of the suspended material melting furnace. A known method is, for example, to decrease the feed, that is, to feed less amount of concentrated material and reaction gas to the reaction tank. For productivity reasons, it would also be satisfactory to succeed in decreasing the thermal balance without decreasing the feed.
    [007] Patent Application WO 2009/030808 describes a concentrated material burner according to the preamble described in the present claim 16.
    Brief Description of the Invention [008] The purpose of the present invention is to solve the problems mentioned above.
    [009] The purpose of the invention is achieved by the method to control the thermal balance of the reaction vessel of the suspended material melting furnace.
    [0010] The invention is also related to a concentrated material burner to feed gas
    Petition 870170089586, of 11/21/2017, p. 10/35
    4/16 reaction and powdery solid matter inside the reaction vessel of the suspended material melting furnace.
    [0011] The preferred embodiments of the invention are also presented in the application.
    [0012] The invention also refers to the use of the method and the concentrated material burner.
    [0013] In the solution according to the invention, the concentrated material burner is used to feed endothermic material, to form a part of a suspension that is formed of powdery solid matter and reaction gas, so that a mixture containing solid matter powder, reaction gas and endothermic material is formed in the reaction vessel of the suspended material melting furnace.
    [0014] The solution according to the invention allows a reduction in the temperature of the reaction vessel, without decreasing the supply. This is due to the fact that the endothermic material that is mixed as a component with the mixture that is formed from the reaction gas and powdery solid matter, consumes energy in the reaction tank. An endothermic material in the form of a liquid refrigerant can, for example, consume energy through evaporation in the reaction vessel and the evaporation energy is removed from the substances in the reaction vessel. Possibly, the endothermic material may also contain components, which under the conditions of the reaction vessel may disintegrate into smaller partial components, consuming energy according to endothermic reactions. Therefore, the temperature in the reaction vessel can be lowered in a controlled manner.
    [0015] The solution according to the invention allows an increase in the casting capacity, that is, an increase in the feed. This is due to the fact that the increase in temperature due to the increase in food
    Petition 870170089586, of 11/21/2017, p. 11/35
    5/16 can be corrected, respectively, by increasing the endothermic material feed.
