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.

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.

Hotspots typically result from damaged or missing insulation or compromised metal surfaces that allow heat to escape. KKI has experienced fabricators and insulators who can repair your oxidizer. This may involve replacing damaged metal to provide a secure base for reattaching insulation modules and restoring proper thermal protection.

We can evaluate your heat exchanger, whether metal recuperative or ceramic regenerative, to see if upgrading to a more efficient type is possible. Adding a catalyst might also help reduce gas usage. In some cases, replacing the oxidizer with a more efficient system is the best option. We can check our inventory for suitable units or design a custom system tailored to your needs.

The burner provides the heat required to raise the gas stream to the oxidation temperature needed to destroy VOCs.
