Regenerative Thermal Oxidizers (RTO)

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.

The refractory lining insulates the combustion chamber and helps retain heat. If the refractory becomes cracked, worn, or damaged, heat can escape from the chamber, forcing the burner to fire more frequently to maintain temperature. Over time, this increases fuel consumption and can create hot spots that shorten equipment life.

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.

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

Regenerative thermal oxidizers (RTOs) typically have a 0.5 second to 1.0 second dwell time for most applications.
