  • Apparatus and process for carbon removal from fly ash
    Patent number: 6202573
    Abstract: A new apparatus and process for the removal of carbon fly ash, whereby carbon removal occurs through oxidation. The ignition of the carbon is accomplished by bulk heating and impingement of a suspended bed of fly ash by a heated oxidizing gas stream, and the desired level of carbon burnout is accomplished in a single chamber apparatus by maintaining combustion conditions. A substantial amount of the carbon removal may occur in the chamber in an environment that maintains temperature and oxygen levels lower than that required for carbon ignition. In one preferred embodiment of the invention, the carbon ignition and burnout may be performed in a single chamber by maintaining zones of varying temperature and oxygen level.

  • Apparatus and process for carbon removal from fly ash
    Patent number: 5868084
    Abstract: A new apparatus and process for efficient removal of carbon from fly ash has been developed, whereby carbon removal occurs through oxidation as combustion. The ignition of the carbon is accomplished by bulk heating and molecular impingement of a suspended layer of fly ash by a heated oxidizing gas strewn, and the desired level of carbon burnout is accomplished by maintenance of combustion conditions.
