Abstract:
1. A two-chamber incinerator system comprising: a primary combustion chamber having a combustion bed for receiving waste therewithin; a primary combustion air source connected to the primary combustion chamber providing a primary combustion air supply into the primary combustion chamber; a secondary combustion chamber, downstream of the primary combustion chamber; an eductor attached to an inlet region of the secondary combustion chamber; a supplemental fuel source connected to the eductor providing fuel into the secondary combustion chamber; a secondary combustion air source connected to the secondary combustion chamber providing a secondary combustion air supply into the secondary combustion chamber; a burner in the eductor for igniting the fuel in the secondary chamber; an exhaust fuel-gas conduit, connecting the primary combustion chamber to the eductor, the exhaust fuel-gas conduit feeding fuel-gas from the primary combustion chamber to the secondary combustion chamber; an exhaust gas recirculation conduit, connecting the secondary combustion chamber to the primary combustion chamber, wherein the exhaust gas recirculation conduit feeds exhaust gas from the secondary combustion chamber to the primary combustion chamber, the exhaust gas, in combination with the primary combustion air, igniting the waste within the primary combustion chamber, wherein the fuel-gas conduit and the exhaust gas recirculation conduit form a recirculation loop between the primary combustion chamber and the secondary combustion chamber; and a bypass combustion air conduit for supplying the secondary combustion air from the secondary combustion air source directly into the secondary combustion chamber.
