ABSTRACT OF THE DISCLOSURE A metalurgical furnace 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 discharging below the metal-line in a furnace therefore having a refractory or graphitic bottom and side-walls and having a roof and having a feed-entrance for introducing the solid feed-material into the furnace from above the level of the molten metal, and said furnace having an opening for drawing off molten-metal, and said process involving the use of internal-combustion burners extending down- wardly through the roof of the furnace with their discharge ends substantially below the melt-level and with their other ends out- side the furnace, each of the burners having a refractory or metallic combustion chamber and a coolant-jacket surrounding said combustion chamber, with the coolant-inlet and the coolant-outlet of the jacket being near the other end of the burner, outside the furnace.
