Abstract: For continuously reducing and melting metal oxides and, respec- tively, metallic materials pre -reduced to a large extent, fuels are completely burned within a melting receptacle. The melting receptacle (8) is tightly passing at its upper side into at least one supply space (7) essentially extending in horizontal direction. The effluent gases of the complete combustion within the melting receptacle (8), are emerging via the supply space (7), coal dust being supplied via a coal dust nozzle (15) to the hot combustion gases immediately prior to entering the sup- ply space (7). The hot combustion gases essentially consisting of CO2 and H2O are at least partially converted to CO and H2 and cooled and are passed with a temperature exceeding 800°C within the supply space (7) in countercurrent to the charge ma- terial (10) to be supplied into the melting receptacle (8). While passing through the charge material (10), the combustion gases supplied with a temperature exceeding 800°C are transmit- ting their heat to the charge material , noting that when using a charge material of metal oxides an extensive pre-reduction can be effected within the supply space (7). While passing through the charge material, the hot combustion gases are cooled and the hot combustion gases are discharged with temperatures ex- ceeding 100°C, preferably with a temperature of approximately 150°C for avoiding condensation of water within the charge material.
