Abstract
A portion of a steam pyrolysis tubular coil, preferably the outlet portion, is provided with an insert to provide a radiation absorption surface within the tube. The insert is dimensioned to increase heat flux without adversely increasing pressure drop. A preferred insert has a central body and outwardly extending vanes in contact with the interior of the coil.
