Effect of vortex finder diameter on pressure drop across the MR-deDuster cyclone

A study on the effect of different vortex finder diameter towards the operating conditions of the MR-deDuster cyclone system had been carried out in a pilot plant scale unit. Two different vortex finder diameters of 90 and 60 mm of four miniature cyclones with axial inlet entry were evaluated for its pressure drop under various volumetric air flow rates. Results showed that the pressure drop varies inversely proportional to the diameter of the vortex finder. The pressure drop across the MR-deDuster was also simulated by using 3D computational fluid dynamics (CFD) via FLUENT 15.0 which clearly illustrated the pressure profile of MR-deDuster.
