Optimization of Operating and Design Parameters of Water only Cyclone using Cherat Coal in Pakistan

Experiments have been conducted using Water only cyclone to reduce ash in coal from Cherat region of Khyber Pakhtunkhwa in Pakistan, varying the associated design and operation parameters. These parameters were optimized on the bases of yield and the ash percent in clean coal. It was observed that the vortex finder diameter has a greatest effect on the clean coal yield. The selected optimum parameter values were cyclone inclination 30 degree, cyclone inlet pressure 100 kPa, vortex finder diameter 54 mm, apex diameter 26 mm, solid feed concentration 18% and the vortex finder length 240 mm. By optimization the operating and design parameters of Water only cyclone the clean coal of less than 15% ash was produced from 30% raw coal ash. The indigenous coal of the above given specification can be utilized in cement industry.
