Abstract
DANS CE PROCEDE ET CETTE INSTALLATION, ON INTRODUIT LE CHARBON BROYE DANS LE TUBE 2 EN 3, CE PRODUIT SUBIT UN PRESECHAGE DANS LA PARTIE BASSE DU TUBE. EN 4, CE TUBE SE RAMIFIE EN UNE BRANCHE PRINCIPALE, LARGE MAIS QUI PRESENTE UN COUDE, DE SORTE QU'ELLE NE TRANSPORTE QUE LE GAZ ET LES FRACTIONS FINES DU CHARBON BROYE TANDIS QUE LES FRACTIONS GROSSES POURSUIVENT LEUR TRAJET EN LIGNE DROITE, PAR INERTIE ET ABOUTISSENT, PAR LA BRANCHE SECONDAIRE RECTILIGNE, DANS UNE ZONE RETRECIE ET FORTEMENT COURBEE. LA, ELLES SE SEPARENT DU GAZ ET SONT RECUEILLIES DANS UN COLLECTEUR QUI LES REINTRODUIT EN 7 DANS LE TUBE 2 AVEC UNE VITESSE A PEU PRES NULLE. ELLES PRESENTENT ALORS UNE GRANDE DIFFERENCE DE VITESSE AVEC LE COURANT DE GAZ CHAUD, CE QUI FAVORISE L'ECHANGE DE CHALEUR AVEC CE GAZ ET ACCELERE LE CHAUFFAGE DU CHARBON.
