摘要：Considering the non-linear characteristics of the reformer tube material with temperature changes and the influence of the fluid inside and outside the tube, we suggest to establish a thermal-fluid-solid coupling model and calculation method for the reformer tube of the hydrogen production reformer. The multi field coupling theory is used to analyze and study the stress distribution of the fluid in the reformer tube under different process conditions, different inlet temperature and different inlet flow rate.We found that under hot operating conditions, as the fluid inlet temperature in the tube increasing, the maximum equivalent stress of the overall reformer tube structure gradually decreased. As the flow rate gradually increasing, the maximum equivalent stress of the reformer tube decreased gradually and then increased. In this paper, all the technological parameters come from the actual production conditions, so the research results provide a certain reference for safe production.
