In the process for thermal cracking of hydrocarbons in the presence of steam, the filling mixture passes through outer heated tubes with helical inner fins, as well as to make the temperature inside the tube wall and on the tube cross section more uniform, as well as the tube inner wall In order to eliminate the deposition of fission coke in the phase, a vortex flow is generated in the gas mixture and gradually fuses into the core zone with the axial flow dominant at increasing radial distance from the fins. |
