Abstract

The present invention provides for thick fins on the surface of coils or tubes in a steam cracking furnace. The fins have a thickness at their base from1/4 to ¾ of the radius of the furnace tube. The fins have grooves or protuberances on not less than about 10% of a major surface. The fins help increase the radiant heat taken up by the tube from the walls and combustion gases in the furnace.
