| Abstract | The effect of vortex finder heights on separation efficiency of dust cyclone has been experimentally investigated in this present study. The separation efficiency of three cyclones with different vortex finder heights was measured as a function of particle size of dust and velocity of air. Husk ash was used as dust particles in the air. Three values of vortex finder heights of cyclone including 30, 50 and 70 mm were investigated. The inlet velocities of air were varied from 6.61, 7.35, 8.06 to 8.81 m/s. The dimensions of husk ash were conducted into four ranges, 0-150, 150-250, 250-500 and 500-850 micro meters. The experimented result reveals that the separation efficiency of dust cyclone was increased when the particle size of husk ash and the air velocity were increased for all of vortex finder heights. The vortex finder height of 50 mm was observed to have more separation efficiency than the others for all air velocities and particle sizes. The maximum separation efficiencies at the vortex finder height of 50 mm and the velocity of 8.81 m/s for all aforementioned particle ranges were found 98.85, 99.51, 99.69 and 99.91 percentages, respectively. |
