초록

In order to obtain the optimal design of a char removal cyclone, the effect of the vortex finder height and inlet shapeon its performance are numerically carried out. The pressure drop and collection efficiency are calculated for four differentcyclones with different vortex finder heights and inlet shapes. To validate the present numerical process, the calculatedpressure drops for two types of cyclones are compared with experimental results and the results show a good agreementbetween experimental and numerical results. From the results, increasing the height of the vortex finder, the collectionefficiency is increased. As for cyclone inlet shapes, the tangential one is characterized by lower efficiency compared withthe volute counterpart. The current result can be used for the design of cyclones with high collection efficiency, especiallyfor removing tiny char which is generated during fast pyrolysis process of waste biomass.
