The Anguil Thermal Recuperative Oxidizer destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs), and odorous emissions discharged from various industrial processes using thermal oxidation and heat recovery.
Anguil’s thermal recuperative oxidizers incorporate flexible heat exchanger arrangements, from cleanable tubes ideal for applications with particulates, to shell side exposure combined with soot blowers for silicone dioxide (SiO2) applications. The heat exchanger also minimizes the system’s fuel consumption with the system being self-sustaining at moderate Lower Explosive Limits (LELs).

How Does the Thermal Recuperative Oxidizer Work?
The Thermal 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 (1,450-1,800ºF / 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 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.
