Regenerative Thermal Oxidizer for Emission Control

Product Announcement from Anguil Environmental Systems, Inc.

Regenerative Thermal Oxidizer for Emission Control-Image

The Anguil RTO achieves emission destruction through the process of high temperature thermal combustion, converting the pollutants to carbon dioxide and water vapor while reusing the thermal energy generated to reduce operating costs.  It differs from the catalytic, recuperative and direct-fired oxidizer technologies in that destruction is achieved with little to no auxiliary fuel required once the RTO is brought up to temperature.  

How the Regenerative Thermal Oxidizer Works:

VOC and HAP laden process gas enters the oxidizer through an inlet manifold to flow control, poppet valves that direct these gases into the first energy recovery chamber 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 second 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.
