Abstract

In this study, CPFD was applied to investigate the hydrodynamics characteristics of CFB waste biomass combustor. The lower part of the CFB riser shows higher solid volume fraction and pressure. The axial particle velocity is higher close to the center of the CFB riser and solid particles represent negative axial velocity near the wall. These characteristics of solid flow affect the reaction rate of the solid fuel as well as the erosion rate of the surface wall. The CPFD simulation results can be further applied for sensitivity analysis during scale-up design.
