Title (EN) ENHANCED HEAT TRANSFER SYSTEM
(FR) SYSTEME DE TRANSFERT THERMIQUE AMELIORE
Abstract:
(EN) A method and apparatus for heating or cooling a solid material (93) in a process vessel (80) is disclosed. The method includes supplying a working fluid to a vessel which holds a packed bed (93) of the solid material. The method is characterised by reversing the flow of the working fluid to enhance heat transfer between a heat exchange fluid and the solid material.
(FR) L'invention concerne un procédé et un dispositif qui permettent de chauffer ou de refroidir un matériau solide (93) dans une cuve de traitement (80). Selon le procédé, on amène un fluide thermodynamique à une cuve qui contient un lit fixe (93) de matériau solide. Le procédé est caractérisé par le fait que l'on inverse l'écoulement du fluide thermodynamique afin d'améliorer le transfert thermique entre un fluide d'échange thermique et le matériau solide.
