Zusammenfassung:Provided is an improved falling-film heat exchanger that maximizes the amount of feed stream contacting the heat exchange surface of the heat exchange tubes. The falling-film heat exchanger includes two important features: a spray member (60) and a tube insert (70) for directing feed stream to the tube wall. La présente invention concerne un échangeur de chaleur à film tombant amélioré qui augmente au maximum la quantité de courant d'alimentation entrant en contact avec la surface d'échange de chaleur des tubes d'échange de chaleur. L'échangeur de chaleur à film tombant comprend deux éléments importants : un élément de pulvérisation et une pièce d'insertion de tube destinée à diriger le courant d'alimentation vers la paroi du tube.
