The CFD Simulation of Cyclone Separator with the Counter-cone in the Updraft Gasification Process

Abstract

The performance of cyclone separator as the hot-gases clean up utilization in the updraft gasification system was studied through the Computational Fluid Dynamic (CFD). The hot-gases clean up utilization system is important part due to the effect on the gasification process, in particular on the quality of Syngas (Synthesis Gas). Therefore, the aim of this study is to find the best performance of the cyclone separator in the gasification apparatus that can clean the syngas from the particulates. The CFD simulation was performed to determine the effect of adding the counter-cone in the cyclone separator to the trend of the performance of tangential velocity, pressure profile, and pressure drop in the gasification process. The Reynold Stress Model (RSM) was employed for the for swirl flows modeling accuracy. The performance of ash separation was predicted by using the path-lines in the cyclone separator and the pressure drop in the vortex finder. The results of this simulation show that by adding the counter-cone in the cyclone separator increasing the performance of particulates trap and the path-lines of particle diameter.
