- Model TRO - Thermal Recuperative Oxidizer



The Anguil Thermal Recuperative Oxidizer destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions that are often discharged from various industrial processes. The air pollution control device uses the proper mix of temperature, residence time, turbulence and oxygen to achieve destruction or thermal oxidation.


The Thermal Recuperative Oxidizer is designed based on volume of airflow, organic vapor concentrations and desired destruction efficiency. During operation, HAP and VOC laden air is drawn into the system fan and discharged into the inlet where it is preheated in the tube side (typically) of a shell-and-tube style heat exchanger.  Contaminated air then passes by the burner where it is raised to the thermal oxidation temperature (1,200-1,800ºF / 650-1,000ºC) for the specified residence time (0.5 - 2.0 seconds) and an exothermic reaction takes place. The pollutants are converted to carbon dioxide, water vapor and heat with within the reactor chamber.

The hot, purified air then passes again through the shell side (typically) of the heat exchanger where the energy released by the reaction is used to preheat the incoming air. The heat exchanger minimizes the system's fuel consumption with the system being self-sustaining at moderate Lower Explosive Limits (LELs). Finally, the contaminant-free air is exhausted into the atmosphere.

Applications which carry silicones may have the configuration reversed, allowing the hot silicone laden air to pass through the tube side of the heat exchanger after the burner for maintenance and cleaning.
