Abstract

PROCEDE DE REFROIDISSEMENT D'ARTICLES EN VERRE PAR INTRODUCTION DANS UN LIT FLUIDISE DE PARTICULES DANS DES CONDITIONS THERMIQUES FAVORABLES A UN ECHANGE DE CHALEUR. B.SUIVANT L'INVENTION, LA VITESSE DU GAZ DE FLUIDISATION EST SUPERIEURE A LA VALEUR V CORRESPONDANT AU PIC D'EXPANSION SUR LA COURBE "HAUTEUR DU LITVITESSE DU GAZ", MAIS N'EST PAS SUPERIEURE A 1,2FOIS CETTE VALEUR. ON EMPLOIE UN DISPOSITIF DE FLUIDISATION A FOND POREUX, LES DIMENSIONS DES PORES ETANT INFERIEURES A 60 MICROMETRES. C.LE PROCEDE CONVIENT NOTAMMENT POUR LA TREMPE THERMIQUE DE FEUILLES DE VERRE MINCES, PLANES OU BOMBEES.
