Patent ID: 7569193

Claim:
An apparatus for use during the abatement of a semiconductor manufacturing process comprising: an upper reaction chamber having: an interior porous wall that defines a central chamber; an outer wall that surrounds the interior porous wall and that defines an interior space between the outer wall and the interior porous wall; at least one waste gas inlet in fluid communication with the central chamber and adapted to introduce a gaseous waste stream to the central chamber; at least one fuel inlet adapted to introduce a fuel into the central chamber, where the fuel inlet is positioned to introduce fuel through a path that does not pass through pores of the porous wall; at least one oxidant inlet adapted to introduce an oxidant into the central chamber, where the oxidant inlet is positioned to introduce oxidant through a path that does not pass through pores of the porous wall; a thermal mechanism positioned within the central chamber and adapted to form reaction products from the gaseous waste stream within the central chamber; a fluid delivery system adapted to provide a fluid to the central chamber through the interior porous wall at a sufficient force to reduce deposition of reaction products on an inner surface of the interior porous wall of the central chamber; and a lower reaction chamber coupled to the upper reaction chamber and having: a gas flow chamber in fluid communication with the central chamber, the gas flow chamber having an inlet and outlet for passing the gaseous waste stream and reaction products through the gas flow chamber; a water delivery system adapted to generate a flowing liquid film on an interior surface of the gas flow chamber so as to reduce deposition and accumulation of particulate solids on the interior surface of the gas flow chamber; and at least one inlet adapted to introduce an oxidant to the gaseous waste stream.
