    Abstract: A cracking furnace for carrying out chemical reactions wherein the furnace is a closed chamber having a top bottom and at least two relatively smooth vertical parallel walls. A plurality of vertically extending hollow tubes for carrying a medium therethrough are disposed in the chamber, an odd number of the tubes forming a coil with all of the tubes in one coil being joined to adjacent tubes in the same coil. The coils include inlet and outlet openings, the inlet openings being on one side of the chamber and the outlet openings on the other. At least two coils are adjacent in such a manner that one is the mirror image of the other. Burner means operatively engages the inlet openings and a combustion gas outlet in the chamber is in communication with the outlet openings.
