  • Methods and apparatus to thermally destruct volatile organic compounds
    Patent number: 11338243
    Abstract: Methods and apparatus to thermally destruct volatile organic compounds are disclosed. An example thermal oxidizer for a furnace includes: an oxidation chamber comprising an inlet configured to receive exhaust gases from a furnace and an outlet configured to output resultant gases; and a plurality of heating elements within the oxidation chamber configured to heat the exhaust gases to oxidize one or more components of the exhaust gases between the inlet and the outlet to result in the resultant gases, the plurality of heating elements comprising resistive heating elements forming coils having respective axes, the plurality of heating elements being oriented within the oxidation chamber such that the axes of the coils are transverse to an exhaust gas flow direction from the inlet to the outlet of the oxidation chamber.
    Type: Grant
