| Abstract: | The internal combustion of W radiant tube was simulated using Fluent software. The simulation of the combustion flow field was carried out under different excess air coefficient, different gas flow and different preheating temperature. The feasible excess air coef ficient, feasible gas flow and reasonable preheating temperature were obtained, based on which, the deformation and stress distribution of the radiant tube were computed through the fluid solid coupling analysis. Certain theoretical reference can be provided for the similar problems because of the comprehensive analysis of the radiant tube herein. |
