Abstract

 In this paper, aiming at the problem that the deformation of the 33000 mm roof steel frame structure of a waste heat boiler is more serious, the deformation, stress, and bending moment of the roof steel frame structure are numerically simulated by ANSYS finite element analysis software. The numerical simulation results show that the maximum deformation of the steel frame structure on the top of the furnace is 8.19 mm, which is much smaller than the displacement allowable value of the top floor of 66 mm. The maximum stress is 146.429 MPa, which is lower than the allowable stress fy=257MPa of Q235 steel. The bending moment of the steel frame structure is mainly concentrated on the large plate beam, which is located near the drum support. The finite element analysis results of the boiler roof steel frame structure show that the strength and stiffness of the boiler roof structure meet the requirements of the corresponding specifications, and the steel frame structure is safe.
