3D full-loop simulation of an industrial-scale circulating fluidized boiler

摘要：

In this study,3D full-loop simulations of a CFB boiler are carried out.FLUENT?6.3 is used as the solver,where an Eulerian multiphase model with EMMSbased drag model is employed.The wide particle size distribution are considered and divided into several groups to better represent the polydisperse behavior of ash particles.The simulation shows that,compared to the conventional drag model,EMMS-based model predicts more reasonable pressure drop of furnace and larger slip velocity at the lower elevations of the furnace.Further work is under way to improve the full-loop simulation.
