Systems and methods for improved waste gas abatement

A system for combustive abatement of waste gases comprising:

• a) a waste gas inlet;
• b) an inlet manifold configured to receive the waste gas inlet, the inlet manifold comprising:
• a first plenum chamber having a first exterior wall and a first permeable interior wall,
• a first plenum inlet configured to supply a first gas through the first plenum chamber to the first permeable interior wall, and
• at least one aperture through the first plenum chamber, the at least one aperture being coupled to the waste gas inlet and extending through the first exterior wall and the first permeable interior wall of the first plenum chamber;
• c) a thermal reaction chamber coupled to the inlet manifold and configured to receive (i) a waste gas from the waste gas inlet through the at least one aperture and (ii) the first gas through the first permeable interior wall, the thermal reaction chamber comprising:
• a central chamber,
• a second plenum chamber at least partially surrounding the central chamber having a second plenum inlet configured to receive a supply of a second gas,
• a second permeable interior wall between the central chamber and the second plenum chamber, and
• a second exterior wall at least partially defining the second plenum chamber;
• and
• d) a controller configured to maintain a flow of the first gas, the second gas, or both the first and second gas, and control combustion at the surface of at least a portion of the first permeable interior wall and at least a portion of the second permeable interior wall,
• wherein
• i. at least a portion of the surface of the first permeable interior wall comprises a burner surface configured for permeation of a mixture comprising combustible gas and at least a portion of the surface of the second permeable interior wall is configured for permeation of a mixture comprising non-combustible gas;
• or
• ii. at least a portion of the surface of the second permeable interior wall comprises a burner surface configured for permeation of a mixture comprising a combustible gas and at least a portion of the surface of the first permeable interior wall is configured for permeation of a mixture comprising non-combustible gas.
