Regenerative thermal oxidizer how does it work

The VOC laden air stream enters the first heat exchange bed where the stream passes directly through the media where it is preheated in route to the combustion chamber where a burner adds any heat necessary to reach optimum combustion temperature and complete the oxidization process.

The bed which was the last inlet bed will always be purged with clean air before becoming the outlet bed. The dirty air from the last inlet bed has to be cleaned out in order to achieve high destruction efficiency.

The Temperature Safety System TSS also monitors the temperature in the regenerators, combustion chamber in three places, and in the valve assembly's inlet and outlet.

This helps safeguard the system from extreme temperature fluctuations that cause thermal stress and overall system fatigue. As soon as the required operating set-point temperature is reached, the TSS enables the process lines to feed into the oxidizer, or holds the system in idle mode until production is ready. When production is ready the fresh air purge damper closes and one or more of the diverting dampers open to draw the volatile organic compounds VOCs off the process lines. A booster fan draws one or more VOC-laden exhausts from your process lines into the system.

From there, VOCs are directed into one of the system's regenerators an internally insulated vessel containing ceramic media. The contaminated gases are passed through the first regenerator, where energy is transferred from the ceramic RTO media to the gas in order to elevate the temperature. This elevated temperature approaches the ignition level for most solvents and then is directed from the ceramic bed into the combustion chamber.

As the process stream exits the ceramic bed and travels through the internally lined combustion chamber, minimal heat is added. The oxidized gases are then directed to the second regenerator to absorb the heat energy.

As the ceramic media loads with sufficient heat, the CPI Posi-Seal Valves switch, and the gases are reversed through the system where the second regenerator bed continues the energy transfer and oxidation cycle before being released to the atmosphere, or to auxiliary heating systems such as; secondary air to air recovery, air to water recovery, air to oil recovery, or directly back to the process in a closed loop direct recirculation process.

The regenerative thermal oxidizer is in compliance with clean air regulations. Catalytic Products International has been designing, manufacturing, and installing the world's most innovative thermal oxidizers since Throughout our long history, we continually strive to offer the most advanced air pollution control equipment. Each system is custom engineered to exceed all worldwide air compliance guidelines at the lowest overall costs. Each CPI Regenerative Thermal Oxidizer system is designed around the particular ceramic heat transfer matrix recommended for the application.

CPI RTO systems can be designed using a layered structural ceramic media or a mix of structured and random media saddles , depending on your application's requirements. The thermal heat transfer model is the key to a well designed and efficient system. With thermal rate efficiencies TRE ranging from 85 percent to 97 percent , you can be assured that even the lowest VOC concentrations can be economically destroyed. The CPI RTO also employs a bake-out feature that will allow periodic high temperature cleaning of condensate residue from the lower levels of the ceramic media beds and cold face support.

Secondary Heat Recovery Solutions including direct or indirect heating system. Phone: CALL Regenerative Thermal Oxidizer. How an RTO Works 1. The complete system is designed with a modular approach for the most cost-efficient solution. This modular approach satisfies your needs for a competitive installation cost and ensures that the Posi-Seal valves are properly installed and aligned prior to leaving the factory.
