Abstract

A.INSTALLATION POUR RECUPERER LA CHALEUR SENSIBLE ET LA PRESSION DES GAZ DE HAUTS FOURNEAUX EQUIPES D'UN DEPOUSSIEREUR OPERANT A SEC. B.INSTALLATION POUR RECUPERER SOUS FORME D'ENERGIE LA CHALEUR SENSIBLE ET LA PRESSION DES GAZ S'ECHAPPANT AU SOMMET D'UN HAUT FOURNEAU 1 EN LES GUIDANT VERS UN DEPOUSSIEREUR 4 OPERANT A SEC AFIN D'EN ELIMINER LA POUSSIERE TOUT EN LES MAINTENANT A LEUR PRESSION DE SORTIE AVANT DE LES INTRODUIRE DANS UNE TURBINE9 AUX FINS D'EXPANSION. POUR PROTEGER LE DEPOUSSIEREUR A SEC QUAND LES GAZ S'ECHAPPENT DU HAUT FOURNEAU A UNE TEMPERATURE ANORMALEMENT ELEVEE, ON A PREVU UN CANAL DE CIRCULATION RELIANT LE HAUT FOURNEAU AU DEPOUSSIEREUR, DANS LEQUEL EST MONTE UN INJECTEUR13 QUI INTRODUIT UN FLUIDE DE REFROIDISSEMENT DANS LES GAZ EN REPONSE A UN SIGNAL ISSU D'UN DETECTEUR THERMOMETRIQUE 16 PLACE PRES DE LA SORTIE DU DEPOUSSIEREUR. LE DETECTEUR PLACE PRES DE LA SORTIE DU DEPOUSSIEREUR MESURE LA TEMPERATURE SANS RETARD. L'UTILISATION D'UN DEPOUSSIEREUR OPERANT A SEC PERMET D'ALIMENTER LA TURBINE AVEC DES GAZ QUI N'ONT PRATIQUEMENT PAS REFROIDI, PERMETTANT AINSI DE RECUPERER UNE PLUS GRANDE QUANTITE D'ENERGIE. C.APPLICATIONS A LA SIDERURGIE ET PLUS PARTICULIEREMENT AUX INSTALLATIONS ANNEXES DES HAUTS FOURNEAUX.
