Abstract
PROCEDE D'INJECTION CONTINUE DE LIGNITE A GRAIN FIN DANS LE CREUSET D'UN HAUT FOURNEAU. SELON L'INVENTION, L'INJECTION SOUS PRESSION DU POUSSIER DE LIGNITE PAR LES TUYERES DU HAUT FOURNEAU EST EFFECTUEE DE MANIERE TELLE QUE LES PARTICULES DE POUSSIER SE MEUVENT, A LA SORTIE DU TUYAU D'AMENEE, A UNE VITESSE INITIALE NOTABLEMENT INFERIEURE A CELLE D'ENTREE DU VENT CHAUD DANS LA TUYERE OU DANS LE CREUSET. LE GAZ PORTEUR DU POUSSIER REPRESENTE MOINS DE 4 DE LA TOTALITE DU VENT CHAUD. CE GAZ PORTEUR PEUT ETRE DE L'AIR FROID OU UN MELANGE GAZEUX REDUCTEUR, TEL QU'UN GAZ DE GUEULARD EPURE, RECYCLE ET EVENTUELLEMENT REGENERE.
