REGENERATIVE THERMAL OXIDIXER (RTO)

REGENERATIVE THERMAL OXIDIXER (RTO)

A Regenerative Thermal Oxidizer (RTO) is an industrial grade air pollution control device designed to decompose Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs), and other airborne emissions into CO2 and water vapor by heating exhaust air to temperatures over 1,400°F. It is the preferred oxidizer technology for most applications due to its high destruction efficiencies and its ability to recover most of the thermal heat that is generated in the destruction of VOCs and HAPs. Oxidizers come in many different sizes, shapes, and configurations but all operate on the same basic principal of thermal oxidation.

The GeoTherm® II RTO provides the highest performance possible to maximize collection efficiency, minimize maintenance requirements, and provide the protection necessary for trouble-free operation of the emission control systems.

RTO Destruction Efficiency of 95-99%
Thermal Efficiencies +97%
Most Efficient Technology for VOC Abatement

What does a Regenerative Thermal Oxidizer Do?

Regenerative Thermal Oxidizer Basics

RTOs treat contaminated gas streams with high temperature to oxidize the organic compounds along with the energy-saving regenerative process described below.

A system of diverter valves located at ground level control the direction of flow of the gas stream being treated. This valve system acts to direct the gas stream into and out of heat recovery chambers located directly above the valves.

Each heat recovery chamber is a vertical section filled with ceramic media. Working in tandem, the diverter valves alternate the direction of flow through the unit on a pre-determined cycle. This back-and-forth, the regenerative operation allows RTOs to recover up to 97% of the heat generated in the burner chamber and greatly minimizes fuel costs.

With reference to the diagram below, the inlet emission stream passes through the inlet heat recovery chamber where it is preheated to a temperature very near the burner chamber temperature. In the burner chamber, a natural gas burner maintains the temperature at between 1,400ºF and 1750ºF, the temperature required for complete thermal oxidation.

Upon exiting the burner chamber, the emission stream enters the outlet heat recovery chamber. The gas stream passes through the outlet heat transfer media bed where the heat energy gained from the inlet heat recovery chamber and burner chamber is transferred to the ceramic heat exchange media (heat sink). This is the final step in the regenerative process. Typical discharge temperatures from RTO systems are approximately 75ºF above the inlet temperature. Finally, the emission stream exits the RTO system through the outlet diverter valve and is transferred to the stack via the induced draft fan.
