Abstract

Le transfert de chaleur de la caisse chauffante (1) d'un collecteur-répartiteur sur le corps de filière qu'il contient (dans un col de filière (25)) est amélioré du fait que le support (24) du corps est pourvu d'éléments d'absorption de la chaleur (27). Ces éléments sont exposés en service à de la vapeur saturée et comportent des flocons de condensation pour pouvoir capter la chaleur de la vapeur saturée. La chaleur ainsi captée est transféré au corps par l'intermédiaire d'au moins d'un pont thermique.
