Abstract: The instant invention relates to a metallurgical furnace, comprising at least one upper stack (1), at least one lower stack (2), at least one fuel feeder positioned substantially between at least one upper stack (1) and the at least one lower stack (2), at least one row of tuyères (3, 4) positioned in at least one of the at least one upper stack (1) and at least one lower stack (2), the at least one row of tuyères (3, 4) providing a fluid communication between the inside of the furnace and the external environment, positioned in at least one of at least one upper stack (1) and at least one lower stack (2), and further comprising at least one permeabilizing fuel column fed through at least one hood (6), placed in the upper stack (1), which extends longitudinally through the furnace.

Abstract: The present invention pertains to metallurgical processes and equipment and, more particularly, to a metallurgical furnace capable of operating with a broad range of broad range of raw materials and fuels, including those with high levels of impurities. Accordingly, the metallurgical furnace of the present invention comprises (i) at least an upper tub, (ii) at least a lower tub, (iii) at least a fuel feeder positioned substantially between the at least an upper tub and the at least a lower tub, (iv) at least a row of tuyeres positioned on at least one of at least an upper tub and at least a lower tub, the at least a row of tuyeres fluidly communicating inside the furnace with the outside environment, and (v) at least a burner positioned on at least one of at least an upper tub and at least a lower tub. The use of at least a burner jointly with the at least a row of tuyeres generates a very intense release of heat by virtue of the exothermic reactions which occur by this combination.
