Effect of Refractory᾽s Thermal Expansion Coefficient on the Stress Field of the Top of Gasifier

Abstract:

The top of COREX-C3000 gasifier was simulated with a finite element analysis technique. It is studied of the influence of thermal expansion coefficient of the refractories on the temperature field and stress field and the function discipline with different parameters. The results of the simulation indicated that when the coefficient of thermal expansion of working lining and permanent lining are respectively 3.5×10^-6/K and 4.5×10^-6/K, the distortion and initial stress of the gasifier top are much less.
