Spooner - Regenerative Catalytic Oxidiser
A Regenerative Catalytic Oxidiser combines RTO technology with catalyst technology. During operation, the VOC-laden process air enters the oxidiser via flow control valves that direct the stream into energy recovery chambers. A layer of catalyst near the combustion chamber facilitates oxidation at temperatures up to 400°C lower than a standard RTO, further reducing the carbon emissions and operating costs of this already efficient thermal oxidiser.
As it passes through the media bed in the outlet flow direction, the hot, purified air then releases thermal energy, heating the outlet bed and cooling the air so that the outlet temperature is only slightly higher than the process inlet temperature. Poppet or butterfly valves alternate the airflow direction into the media beds to maximize energy recovery within the oxidiser – achieving high destruction efficiency and self-sustaining operation with no auxiliary fuel usage at low concentrations.
