between 100-200 kV/m. The ash feed rate to the separator was between 2-20 kg/hr. Fly ashes were fed to the tribocharging unit by using either a screw feeder or a vibratory feeder. Both feeders contained sealed environmental tanks in which the ashes could be stored. They were metered into a pneumatic transport tube and then entrained in carrier air.
