A tube type cracking furnace, especially an ethylene-cracking furnace includes a convection section (2) and a radiation section (5). At least one enhanced heat transfer member (7) is located in at least one way of a single cracking furnace tube (3) of the radiation section (5). The at least one enhanced heat transfer member (7) includes a first enhanced heat transfer member (7). The first enhanced heat transfer member (7) is placed between 10D and 25D ahead of the limit temperature point of the cracking furnace tube wall, in which D is the inside diameter of the cracking furnace tube (3) which is provided with the enhanced heat transfer member (7). The tube type cracking furnace can make these enhanced heat transfer members (7) distributed well in the radiation section furnace tube (3), when the number of the enhanced heat transfer member (7) added in the radiation section furnace tube (3) is constant, to achieve the optimal effect of enhancing heat transfer.
La présente invention concerne un fourneau de craquage de type tube, en particulier un fourneau de craquage d'éthylène qui comporte une section de convection (2) et une section de rayonnement (5). Au moins un élément de transfert de chaleur amélioré (7) est situé dans au moins une voie du tube unique (3) de fourneau de craquage de la section de rayonnement (5). Le ou les éléments de transfert de chaleur améliorés (7) comportent un premier élément de transfert de chaleur amélioré (7). Le premier élément de transfert de chaleur amélioré (7) est placé entre 10D et 25D devant le point limite de température de la paroi du tube de fourneau de craquage, où D correspond au diamètre intérieur du tube (3) de fourneau de craquage qui est muni de l'élément de transfert de chaleur amélioré (7). Le fourneau de craquage de type tube peut permettre de distribuer correctement ces éléments de transfert de chaleur améliorés (7) dans le tube (3) du fourneau de section de rayonnement, lorsque le nombre d'éléments de transfert de chaleur améliorés (7) ajouté dans le tube (3) du fourneau de section de rayonnement est constant, pour obtenir l'effet optimal d'un meilleur transfert de chaleur.
