Thermal Oxidizer (RTO) design, resulting in a system that achieves emission destruction at temperatures 600 to 800 °F (315-427°C) lower than a standard RTO.  VOC and HAP laden process gas enters the oxidizer through an inlet manifold to flow control, poppet valves that direct this gas into energy recovery chambers where it is preheated. The process gas and contaminants are progressively heated in the ceramic media beds as they move toward the combustion chamber.

Catalyst placed near the combustion chamber helps oxidize the VOCs and HAPs in an exothermic reaction. Since catalytic oxidation occurs at lower temperatures, a layer of catalyst is used in conjunction with the ceramic packing in an RTO or as a replacement of a portion of the ceramics.  As a result, fuel consumption required to preheat incoming emissions could be lowered by 50 to 95 %, further reducing the carbon emissions and operating costs of the already efficient thermal oxidizer.  Depending on the process conditions and gas prices, the payback on catalyst costs could be as low as three months.

The hot purified air releases thermal energy as it passes through the media bed in the outlet flow direction. The outlet bed is heated and the gas is cooled so that the outlet gas temperature is only slightly higher than the process inlet temperature. Poppet valves alternate the airflow direction into the media beds to maximize energy recovery within the oxidizer. The high energy recovery within these oxidizers reduces the auxiliary fuel requirement and saves operating cost. The Anguil oxidizer achieves high destruction efficiency and self-sustaining operation with no auxiliary fuel usage at low concentrations.
