Abstract

a. Procédé de récupération d'énergie contenue dans les gaz d'échappement d'un haut-fourneau, procédé selon lequel on introduit les gaz d'échappement du haut-fourneau dans une turbine, on transforme une partie de l'énergie des gaz d'échappement en énergie servant à entraîner en rotation l'arbre de la turbine et on recupère l'énergie sous la forme d'énergie électrique. b. Procédé caractérisé en ce qu'on utilise une turbine axiale et l'angle de fixation des aubes fixes de la turbine est modifié en fonction des variations de la pression supérieure du haut-fourneau, pour régler cette pression à un niveau prédéterminé.
