The present invention is directed to-wards a fired heater for heating a process fluid that uses U tubes provided with in-creased internal heat transfer surface to re-duce tube metal temperatures and coking, and at the same time is not prone to plugging from coke. The fired heater comprises a ra-diant section enclosure with a number of U tubes in the radiant section. The U tubes are formed by connecting one or more tubular sections, and the U tubes are provided with internal generally longitudinal fins. The in-vention also is directed towards a process utilizing a fined heater with U tubes as dis-closed for producing olefins from hydrocar-bon feedstocks.
La présente invention concerne un four à ailettes servant à chauffer un fluide de traitement, qui utilise des tubes en U munis d'une surface d'échange thermique interne amélioré pour réduire les températures du métal des tubes ou la cokéfaction, sans être sujette au bourrage par le coke. Le four à ailettes comprend une fermeture de la section de radiation comportant une série de tubes en U dans ladite section de radiation. Les tubes en U sont formés par emboîtement d'une ou plusieurs sections tubulaires et équipés d'ailettes internes généralement longitudinales. L'invention concerne en outre un procédé mettant en oeuvre le four à ailettes et tubes en U de l'invention pour produire des oléfines à partir de charges d'alimentation d'hydrocarbures.
