ABSTRACT:
An apparatus and method for reducing the amount of unburned carbon in raw flyash, wherein raw flyash containing unburned carbon is introduced into the tribocharger, the tribocharger producing positive and negative surface charges on the respective particles of carbon and flyash, introducing the charged particles into an electrical field containing positively and negatively charged plates, the positively and negatively charged particles being collected on the negatively and positively charged plates, and selectively vibrating the plates to selectively recover the unburned carbon and flyash.
