Tribo-Electrostatic Beneficiation of Fly Ash for Ash

2001-8-5  Abstract-The study was conducted to obtain the scale-up factor and the optimum design criteria for the developmentof a commercial scale electrostatic separator using a continuous, bench-scale electroseparator composed of two verticalelectrode plates and an ejector-tribocharger. Tests of the charge density and separation efficiency to study the removalpossibility of unburned carbon from coal fly ash were evaluated under various operating conditions. It was found thatthe experimental conditions for obtaining the maximum charge density were an air flow rate of3/min 1.75 and m a feedrate of less than 50 kg/hrwhen operated at lower than 30% relative humidity using a SUS304 ejector tribocharger.
