FEA Analysis of a Round Reformer with 4 Pulsating Gas Heaters

Posted on 8:34 pm

Finite Element Analysis (FEA) was performed on a vertical reformer. Shell elements were used to model the reformer body and the attached nozzles. Static analysis was performed considering the operating pressure and temperature of the reformer, the usage of different thickness and material for construction. The effects of wind, seismic, and gravity loadings were also considered in the FEA. After determining the adequacy of the design, based on ASME Section VIII, Division 1 and Division 2, modal analyses were performed to determine the natural frequencies and mode shapes of the structure. Subsequently, harmonic analysis was performed to evaluate the effect of dynamic loads during the operation of the reformer. Coupled thermal-structural analysis was also performed to assess the effects of thermal stresses on the nozzles with high temperature gradients.
