Heat exchanger consisting of a reservoir with upwardly directed tubes through which flow a liquid to be heated and fluidized bed particles for internally cleaning the tubes. Connected to the reservoir is an external downcomer (5) for collecting fluidized bed particles coming from the top box of the reservoir and to be transported back to the bottom box (7) of the reservoir. The connecting line (4, 2, 1, 3, 6) between downcomer (5) and bottom box (7) is designed as two sections (2, 3) with an expansion bellows (1) arranged between them. The bottom section (3) is connected via two or more connecting stubs (6A, 6B) with the bottom box (7) for the uniform distribution of the flow of fluidized bed particles.
Échangeur de chaleur comprenant un réservoir doté de tubes orientés vers le haut et dans lesquels s'écoule un liquide à chauffer et des particules en bain fluidisé servant à nettoyer l'intérieur des tubes. Se trouve raccordé au réservoir un tube de descente (5) servant à recueillir les particules en bain fluidisé provenant de la boîte supérieure du réservoir et à les ramener dans la boîte inférieure (7) du réservoir. Le conduit de raccordement (4, 2, 1, 3, 6) reliant le tube de descente (5) et la boîte inférieure (7) du réservoir comprend deux sections (2, 3) séparées par un soufflet de dilatation (1). La section inférieure (3) est raccordée par deux ou plusieurs tuyaux de raccordement (6A, 6B) à la boîte inférieure (7) du réservoir afin d'assurer une répartition uniforme de l'écoulement des particules en bain fluidisé.
