Regenerative Thermal Oxidizers (RTO)

Using a bake-out feature can help prevent and remove organic compound buildup in the ceramic media, reducing the risk of plugging and maintaining efficient operation. A preheater or recirculation loop are also possible mitigation methods.

There are two main types of ceramic media. Structured ceramic media is typically block-shaped, with ceramic materials configured in a geometric design. It is often placed in several layers. The other type of ceramic media is random-packed ceramic saddles. These smaller, U-shaped (also called saddle-shaped) ceramic pieces are also availiable in different sizes and are spread and leveled evenly across the media bed. Kono Kogs also offers custom media configurations, such as a hybrid media bed, to best fit the heat transfer and particulate requirements of each process and unit.

Yes, RTOs can be designed to match your specific exhaust airstream characteristics. They are typically optimized for airstreams with solvent concentrations in the 0–10% Lower Explosive Limit (LEL) range. For higher concentrations up to 25% LEL, additional features such as hot gas bypass systems may be needed to ensure safe and efficient operation.

Catalyst utilized in a regenerative catalytic oxidizer (RCO) allows chemical reactions to occur at lower temperatures (700-800F) than they occur in a thermal oxidizer (typical 1400-1450F) or an RTO (typical 1600F).

TOX typically have a 0.5 second to 1.0 second dwell time for most applications.
