The Regenerative Thermal Oxidizer (RTO) destroys Hazardous
Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and
odorous emissions that are often discharged from industrial or
manufacturing processes. Anguil RTOs achieve emission
destruction through the process of high temperature thermal
oxidation, using the proper mix of temperature, residence time,
turbulence and oxygen to convert pollutants into carbon dioxide and
water vapor.
What makes the RTO the most widely used emission abatement
technology is it's ability to repurpose the thermal
energy generated during operation to reduce operating costs and
energy consumption of the system itself.
How the RTO Works
VOC and HAP laden process gas is either pushed or pulled into
the inlet manifold of the oxidizer via a system fan. Flow
control or poppet valves then 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.
Once oxidized in the combustion chamber, 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.
