Definitions
- the swirl flow absorbs the vertebrae detaching at the rib flanks, so that there is no local return of the vertebrae in the manner of a self-contained circular flow into the rib valleys.
- the mean residence time is lower than in the smooth tube and moreover more homogeneous over the cross-section (see Fig. 7). This is confirmed by the higher overall speed in the profile tube with swirl (profile 3) compared to the tube with straight ribs (profile 2). This is ensured in particular when the swirl flow in the area of the fins or the fins extend at an angle of 20 ° to 40 °, for example 30 °, preferably 25 ° to 32.5 ° with respect to the tube axis.
- the heat inevitably different over the circumference of the tube between the sun and shadow side is offered balanced in the tube wall and inside the tube and the heat was quickly dissipated inwards to the core zone. This is associated with a reduction in the risk of local overheating of the process gas on the tube wall and the resulting pyrolysis coke.
- the thermal stress on the pipe material is lower due to the temperature balance between the sun and shade side, which leads to an extension of the service life.
- the temperature is also made more uniform over the pipe cross section, with the result that the olefin yield is better. The reason for this is that without the radial temperature equalization according to the invention inside the pipe inside the hot pipe wall would overcrack and in the pipe center a recombination of fission products would occur.
- the superiority of the finned tube according to the invention (profile 3) compared to a smooth tube (profile 0) and a finned tube with axially parallel fins (profile 1), in which the radial distance between the rib valleys and the fin tips is 4.8 mm, illustrate the data of the following Table.
- the finned tubes all had 8 fins and the same enveloping circle.
- the hydraulic diameter is defined as follows:
