Discover the various types of oxidizers.
Oxidizers generally will be described as thermal or catalytic. While both oxidizers utilize a thermal reaction, the catalytic oxidizers employ a catalyst to cause the reaction to occur at a lower temperature, typically 600 to 800°F (315 to 462°C), compared to 1,500 to 1,800°F (815 to 982°C) for a thermal oxidizer.
Both thermal and catalytic oxidizers can be further divided by whether or not the unit includes integral heat recovery, and the type, if included. Thermal units with no heat recovery are often known as afterburners, while catalytic oxidizers with no heat recovery are known as catalytic oxidizers.
Both thermal and catalytic oxidizers with metallic heat exchangers are known as recuperative thermal or recuperative catalytic oxidizers.
The final oxidizer type, which uses a ceramic heat storage media and either a single or series of flow control valves, and is known as either a regenerative thermal oxidizer (RTO) or a regenerative catalytic oxidizer (RCO).
