| Abstract: | The finite element model of spatial piping element conversion furnace radiant section was built with ANSYS, taking a 10 × 10^4 m3/h hydrogen manufacturing conversion furnace （standard condition） as subject of study. The stress distribution and deformation in each test item was obtained by analyzing the structure of conversion furnace cold installation conditions and the thermal state operating conditions. Furthermore, by method of the local structure sub model en- tity unit, the tee joint of the entrance to line pipe and branch pipe was close analyzed. The strength evaluation of each component was conducted by stress classification. |
