Abstract A method for producing iron in an elongated reaction vessel provided with underbath nozzles and top blowing means, in which carbonaceous fuels, iron ore and/or prereduced ore are fed to the melt and in which the reaction gases escaping from the melt are afterburned with oxygen-containing gases in one or stages, the waste gas aperture of the reaction vessel being offset from the reaction zone of the carbonaceous fuels and thus disposed outside the eruption and splashing area, and the waste gas temperature in the waste gas conduit connected to the waste gas aperture being held above the solidifying temperature of the iron droplets carried along in the waste gas stream, and the waste gas then being cooled to less than 1000°C in an adjoining chamber.
