Abstract
A system for beneficiating landfilled or ponded waste coal fly ash makes use of a carbon reduction kiln comprising multiple independent heat zones so that the waste coal fly ash is preferably exposed to indirect heat when received in such zones. The system may include a carbon capture system operatively connected to the carbon reduction kiln.
Claims4
A system for producing a beneficiated coal ash, the system comprising:
- a waste coal fly ash storage container having a feed mechanism adapted to deliver a landfilled or ponded waste coal fly ash stream;
- a carbon reduction kiln having an inlet and in communication with the feed mechanism, a discharge end, and multiple independent heat zones to expose the waste coal fly ash stream to indirect heat when received in the zones, the carbon reduction kiln having a discharge rate selectively variable between 5 to 50 tons per hour.
