Abstract
This study investigates if the performance of a cyclone can be enhanced as the electric force is incorporated into the centrifugal force. An electrocyclone is utilized to collect the fly ash by combining a cyclone and an electrostatic precipitator. The applied voltage is 25 KV and the flow rates tested are 15.75, 28.75, and 44.26 m3/min. The Particle Counter-Sizer-Velocimeter is used to measure the particle size distribution upstream and downstream of the cyclone and the electrocyclone.
The experimental results show that a high electric field has a significant effect on the grade efficiency. The grade efficiency of the electrocyclone is much larger than that of the cyclone at the low flow rate. The improvement effect is decreased as the flow rate increases. At the highest flow rate, the grade efficiency of the electrocyclone is close to that of the cyclone.
