In order to design the flue and bracket of an SCR denitration system project,the flue model and bracket model were established by using the finite element analysis software ABAQUS and Midas-Gen steel structure analysis software.By analyzing the results of stress,deformation and thermal expansion displacement of the high temperature flue,a reasonable flue reinforcement scheme and support limit scheme are determined,and the support force generated by the high temperature flue on the steel support under the worst working conditions is extracted,and then the support force is added to the steel support model for analysis,so that the calculation results are closer to reality.The results of stability,stress and deformation of steel support are analyzed,which provides theoretical reference and calculation ideas for the design of high temperature flue and support.
