Abstract

Procédé et dispositif pour échauffer un fluide qui s'écoule d'un produit à vaporiser, et est différent de ce produit, dans une installation, comportant plusieurs étages de condensation à températures différentes, destinée à vaporiser et sécher ledit produit. Dans au moins deux étages, l'écoulement de fluide en circulation est échauffé au moins partiellement, au moyen de vapeurs et/ou de condensat provenant d'au moins deux de ces étages de condensation. On obtient le diagramme d'échauffement de l'air représenté sur la figure. Application principale : production de poudres.
