Abstract

L'invention concerne et décrit un registre (2, 2', 22, 42, 62, 82, 102) pour l'échange de chaleur indirect entre un fluide utile présentant des composantes perturbatrices et un fluide caloporteur, comprenant une pluralité de tuyaux (3, 21, 21', 41, 61). Pour que le registre atteigne des durées d'utilisation assez élevées dans un fonctionnement continu, il est prévu qu'au moins un couloir d'écoulement (6, 6', 6'', 26, 46, 46', 86, 86') avec une faible largeur de couloir (7, 47, 87, 87'') et au moins un couloir d'écoulement (6, 6', 6'', 26, 46, 46', 86, 86') avec une grande largeur de couloir (7', 27, 47', 87') sont prévus dans au moins une rangée de tuyaux (4, 4', 24, 44, 64, 84) et ou qu'au moins un couloir d'écoulement (6, 6', 6'', 26, 46, 46', 86, 86') avec une partie (54, 54', 94, 94') étroite, définie par une faible largeur de couloir (7, 47, 87, 87'') et une partie (55, 95) large, définie par une grande largeur de couloir (7', 27, 47', 87') est prévu dans au moins une rangée de tuyaux (4, 4', 24, 44, 64, 84) et que la grande largeur de couloir (7', 27, 47', 87') est conçue pour réaliser une grande vitesse d'écoulement du fluide utile, et la faible largeur de couloir (7, 47, 87, 87''), pour réaliser une faible vitesse d'écoulement du fluide utile.
