Patent ID: 7736599

Claim:
A thermal abatement reactor for removing pollutant from waste gas, the thermal reactor comprising: a thermal reaction unit comprising: an exterior wall having a plurality of perforations for passage of a fluid therethrough; a porous ceramic interior wall defining a thermal reaction chamber, wherein the interior wall comprises at least two ring sections in a stacked arrangement; at least one waste gas inlet in fluid communication with the thermal reaction chamber for introducing a waste gas therein; and at least one fuel inlet in fluid communication with the thermal reaction chamber for introducing a fuel for use during decomposition of said waste gas in the thermal reaction chamber; and means for directing a fluid through the one or more perforations of the exterior wall and the porous ceramic interior wall to reduce the deposition and accumulation of particulate matter thereon; and a water quench unit coupled to the thermal reaction unit and adapted to receive a gas stream from the thermal reaction unit; wherein the total number of perforations in proximity to the waste gas inlet and the fuel inlet is greater than the total number of perforations in proximity to the water quench unit.
