Abstract :In this study, nine different vortex finders insert ignore into journalissuearticles values(VFs); were used for investigations on cyclone pressure drop and particle collection efficiency. The collection efficiencies dropped for larger and smaller vortex finder dimension insert ignore into journalissuearticles values(VFDs);. The collection efficiency increased with increasing vortex finder lengths insert ignore into journalissuearticles values(VFL);. This increase was more obvious and statistically meaningful for the smallest VFD. Pressure drop in cyclones were mainly a function of VFD and increased with decreasing VFD. These effects were also observed in Computational Fluid Dynamics insert ignore into journalissuearticles values(CFD); simulations. A performance map was built for the design of a VF optimized for the highest collection efficiency and the lowest pressure drop. Based on the experimental results, a mathematical model was developed, and the nickel inhibition constants insert ignore into journalissuearticles values(KNi); were found to be 8.75 mg/L.
