Abstract

The invention relates to a method for reducing metal oxides to metallized material by means of contact with reduction gas, wherein an accumulated top gas is dry dedusted and reformed in a raw gas mixture together with gaseous hydrocarbons. The water vapor content of the dry dedusted top gas designated for the preparation of the raw gas mixture is adjusted in a saturator in the countercurrent by means of saturation water, wherein the temperature of the saturation water is adjusted, by mixing cold water with a hot water having a higher temperature than the cold water, in order to produce the saturation water at a target value. The invention further relates to a device for carrying out such a method, having corresponding conduits.
