A metallurgical furnace (1 to 15, in Figures 1 & 2) for and a process of melting, refining and processing metals and for the reduction of ores thereof by the non-stoichiometric combustion of a fluid fuel and a combustion-supporting gas within an internal-combustion burner (21 & 23 in Figures 1-4, detailed in Figures 5-9) discharging below the metal-line (11) in a furnace therefore having a refractory or graphitic bottom (3) and side-walls (7a & 7b) and having a roof (10) and having a feed-entrance (13) for introducing the solid feed-material into the furnace from above the level of the molten metal, and said furnace having an opening (15) for drawing off molten-metal, and said process involving the use of internal-combustion burners (21) extending downwardly through the roof of the furnace with their discharge ends (29 in Figure 5) substantially below the melt-level (11) and with their others ends outside the furnace, each of the burners having a refractory or metallic combustion chamber (26 in Figure 5) and a coolant jacket (27) surrounding said combustion chamber, with the coolant-inlet (65) and the coolant-outlet (66) of the jacket being near the other end of the burner, outside the furnace. |
