Abstract

Targeting the issues of wear, deformation, and tube burst encountered during the operation of the panel superheater in a 600MW supercritical circulating fluidized bed(SCCFB) boiler, this study employs ANSYS finite element analysis software to numerically simulate the temperature distribution and thermal deformation of the panel superheater. A computational model of the panel superheater was established and combined with operational data from the boiler. The results indicate that the maximum wall temperature occurs at the intersection between the panel superheater and the water-cooled wall of the furnace roof, specifically on the fin of pipe No. 50, reaching up to 652.97 ℃, which exhibits localized overheating. The maximum thermal deviation between the fin and the tube wall is 15.3 ℃, while the maximum thermal deformation of the tube panel is 215.85 mm. To address the overheating issue, the mass flow rate of the working medium in each tube was adjusted based on the thermal deviation of the tube panel, effectively reducing the peak temperature and mitigating the risk of overheating. This research provides critical insights for further analyzing operational problems of the panel superheater and optimizing its structural design or operating parameters.
