A Thermal Recuperative Oxidiser destroys emissions through high temperature thermal oxidation, using the proper mix of temperature, residence time, turbulence and oxygen.
During operation of a thermal recuperative oxidiser, VOC-laden air is drawn into the system fan and is discharged into the system’s shell-and-tube style heat exchanger. The air is typically preheated through the tube side of the heat exchanger and then passes the burner, where the contaminated air is raised to the thermal oxidation temperature for the specified residence time and an exothermic reaction takes place. The VOCs in the air stream are converted to carbon dioxide, water vapour and heat within the reactor chamber. The hot, purified air then passes on the shell side of the heat exchanger (typically) 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 LEL levels. Finally, the contaminant-free air is exhausted into the atmosphere.
