Abstract

L'invention concerne un ensemble de déshydratation de l'air atmosphérique à l'entrée d'une soufflante utilisée avec un haut-fourneau. L'ensemble de déshydratation comprend un boîtier 14, comprenant au moins un rotor 15 perméable au gaz contenant un milieu d'adsorption de l'humidité, dans lequel on utilise un gaz chaud obtenu par combustion d'un gaz de rebut pour régénérer le milieu d'adsorption de l'humidité contenu dans le rotor 15. L'invention permet de déshydrater et de nettoyer l'air d'alimentation d'un haut fourneau
