Abstract
A cracking furnace includes a pyrolysis tube 1 for carrying a flow of fluid, the pyrolysis tube including a radially inner body 3 and a radially outer wall 2 which together define an annular flow passage 5, wherein at least one of the radially inner body and the radially outer wall has a centre line which extends helically in a longitudinal direction of the pyrolysis tube, so as to promote rotation of the fluid as it flows along the pyrolysis tube.
