Abstract
Assembly for dehydrating atmospheric air at the input side of a blower for supplying air to a blast furnace comprising at least one gas permeable rotor containing a regenerative moisture absorbent wherein a hot combustion gas obtained by burning a waste gas from the blast furnace is utilized for regenerating the absorbent and wherein means for regulating the relative humidity of the moist air to be dehydrated, which does not need any external heat source, is provided to avoid deliquescence of the absorbent. The rotor preferably comprises a layer containing the absorbent and a layer of an adsorbent capable of adsorbing impurities contained in the air.
