Abstract
L'invention concerne principalement un procédé de réduction des émissions de dioxyde de carbone d'un haut fourneau dans lequel des agents réducteurs sont chargés au gueulard et des combustibles auxiliaires sous forme pulvérisée sont injectés aux tuyères, et qui est essentiellement caractérisé en ce que les agents réducteurs chargés au gueulard comprennent du charbon de bois. Selon un aspect préférentiel de l'invention, la consommation spécifique de charbon de bois chargé au gueulard (15) est inférieure à 20% de la quantité totale d'agents réducteurs chargés au gueulard. En procédant ainsi, une réduction significative des émissions de dioxyde de carbone est obtenue, ainsi qu'une valorisation importante du charbon de bois relativement à la réduction des émissions de dioxyde de carbone. L'invention porte également sur un dispositif permettant de mettre en uvre ce procédé.
