Abstract

L'invention a pour objet un procédé et un four de production de verre en fusion. Des agitateurs 23a et 23b sont disposés transversalement au four et agencés pour extraire de la chaleur du courant de verre d'avancement de manière à réaliser une extraction différentielle de chaleur dans le verre qui suit un courant de retour, en direction de l'extrémité de chargement après passage par les agitateur, par rapport à l'extraction de chaleur réalisée dans le verre qui suit un courant d'avancement en direction de l'extrémité de sortie du four. L'invention est utile dans tous les fours de fusion du verre à marche continue pour arriver à une plus grande efficacité thermique en dépit de débits élevés qui en sont exigés.
