    摘要： The instant invention relates to metallurgical processes and apparatuses and, more particularly, to a metallurgical furnace capable of operating with a wide range of feedstocks and fuels, including those with high levels of impurities. To this end, the metallurgical furnace of the instant invention comprises (i) at least one upper stack (1), (ii) at least one lower stack (2), (iii) at least one fuel feeder (5) positioned substantially between at least one upper stack (1) and the at least one lower stack (2), and (iv) at least one row of tuyeres (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 tuyeres (3, 4) providing a fluid communication between the inside of the furnace and the external environment, (v) at least one hood, called Curtain Wall, located in the upper stack extending longitudinally through the furnace, and (vi) the at least one permeabilizing fuel charging system in the center of the upper stack called the booster charging system. The use of the booster charging system (8) together with the curtain wall (6) enables a channeling of the gas generated in the combustion of the fuel from the lower stack (2) with the air blown by the primary tuyeres (3) and secondary tuyeres (4), more efficiently controlling the gas distribution in the furnace.

    摘要： 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 (1), (ii) at least a lower tub (2), (iii) at least a fuel feeder positioned substantially between the at least an upper tub (1) and the at least a lower tub (2), (iv) at least a row of tuyeres (3, 4) positioned on at least one of at least an upper tub (1) and at least a lower tub (2), the at least a row of tuyeres (3, 4) fluidly communicating inside the furnace with the outside environment, and (v) at least a burner (10) positioned on at least one of at least an upper tub (1) and at least a lower tub (2). The use of at least a burner (10) jointly with the at least a row of tuyeres (3, 4) generates a very intense release of heat by virtue of the exothermic reactions which occur by this combination.

    摘要： The invention relates to a low-shaft arc furnace with a shaft tube, in which at least one electrode is arranged so that it can move axially, a scrap feed in which at least one electrode is arranged so that it can move axially, a scrap feed in the intermediate space between the furnace vessel outer wall and the shaft tube, a hearth adjoining the lower end of the furnace vessel and intended for receiving the molten metal and also a tapping hole for the slag and a tapping hole for the metal as well as burners directed into the furnace chamber. According to the invention, scrap ledges or fingers are provided in the region of the lower end of the shaft tube, facing in the direction of the shaft tube from the outer wall of the furnace vessel and surrounding the shaft tube at a distance. Primary gas burners are also arranged above the scrap ledges or fingers for melting the scrap collecting on the scrap ledges. The annular space between the scrap ledges and the shaft tube is dimensioned such that the liquid metal can flow through the annular space into the hearth.

    摘要： The method according to the invention for operating a PFR lime kiln comprising at least two shafts, which each have a preheating zone, a firing zone and a cooling zone, and a cross-over channel connecting the two shafts, consists substantially of the following method steps: both shafts are operated alternately as a burning shaft and an exhaust gas shaft, combustion air and fuel are fed to the burning shaft, wherein a corresponding flame length is formed and the hot gases developing in the burning shaft reach the exhaust gas shaft via the cross-over channel, wherein at least one parameter of the hot gases characteristic of the formation of the flame length is determined by a direct or indirect measurement in the region of the cross-over channel, and the ratio of fuel to combustion air is controlled depending on said parameter in order to set a predetermined flame length.
