Abstract

PROCEDE POUR AMELIORER LES CARACTERISTIQUES D'UN LIT DE CHAUFFAGE DE PASTILLES DE COMBUSTIBLE TEL QUE LE CHARBON ET POUR EMPECHER LA COALESCENCE DE CES PASTILLES. APRES BROYAGE, LE MELANGE DE CHARBON ET DE CALCAIRE EST FILTRE A UN POSTE DE FILTRATION ET LE PRODUIT OBTENU EST DIRIGE VERS UN BROYEUR A BILLES OU UNE MACHINE A COMPACTER 10. LES PASTILLES FORMEES ET REVETUES D'UN ADDITIF DE BROYAGE SONT DIRIGEES VERS UN POSTE DE CHARGEMENT 14 D'UNE MACHINE DE FRITTAGE 16 A GRILLE MOBILE. LES PASTILLES SONT ENVOYEES DE LA ZONE DE SECHAGE 20 VERS UNE ZONE DE CHAUFFAGE 28 OU ELLES SONT SOUMISES A UN COURANT DESCENDANT A UNE TEMPERATURE SUPERIEURE A 425C ET DE PREFERENCE COMPRISE ENTRE 650 ET 1200C. APPLICATION AU TRAITEMENT DES COMBUSTIBLES.
