Abstract
The three-dimensional numerical simulation of the radiation section of a dehydrogenation furnace was carried out by CFD, the thermal-structure coupling analysis was performed. The full-scale meshing of the geometric model was used in this paper, the temperature field and flow field of the furnace and the furnace tube were simulated. The thermal radiation values and temperature values of the simulation results were compared with the design values, it shows that the simulated values are in good agreement with the designed values. The corresponding numerical calculation can be performed for half or 4/1 of the geometry under the condition with the geometric symmetry of the furnace and the furnace tube being good. The simulation results can provide a reference for the design and optimization of the dehydrogenation furnace.
