    摘要: A method and a device for balancing out amount fluctuations while simultaneously increasing the temperature of an export gas (2) used in a reduction process (1). A first partial amount (3) of a recycling gas (4) is cooled in at least one recycling-gas cooler (5) to form a cold recycling gas (6) and the cold recycling gas (6) is fed to the export gas (2) in a pressure-controlled and/or amount-controlled manner in order to balance out amount fluctuations of the export gas (2). A second partial amount of the recycling gas (4) is fed to the export gas (2) as hot recycling gas (7) having a higher temperature than the cold recycling gas (6). Then an export gas mixture (8) of the cold recycling gas (6) and the hot recycling gas (7) is introduced into the reduction process (1), wherein the temperature of the export gas mixture (8) is higher than the temperature of the export gas (2). The temperature of the export gas (2) or of the export gas mixture (8) is set in such a way that temperature is higher than the dew point or dew point temperature of the export gas mixture.
