Numerical Analysis of Flow Dynamics of Cyclone Separator Used for Circulating Fluidized Bed Boiler

Abstract

The Reynolds stress model (RSM) provided by FLUENT software was applied to study flow dynamics of a cyclone separator used for a circulating fluidized bed. The effect of the depth of the exhaust pipe on the flow field and performance of cyclone separator was investigated computationally. The cyclone flow field pattern has been simulated and analyzed with the aid of velocity components and static pressure distribution. The simulation results reveal the strong swirling flow in cyclone separator. The exhaust pipe depth has an insignificant effect on the pressure drop and velocity distribution.
