Pre-heated air enters the combustion chamber where it is heated to the set-point temperature where oxidation of the VOCs are completed.
Hot treated clean air is cooled as it passes through the heat exchange media and is exhausted from the stack into the atmosphere. Every three 3 minutes the process of air flow reverses direction as the poppet valves switch positions, allowing the heat captured in the ceramic media from the exiting clean air stream to heat the incoming process air. 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.
Whether replacing media to improve the performance of an existing unit or selecting an original equipment manufacturing partner for your new regenerative thermal oxidizer it is important to consider every aspect of the units components. Substandard media could result in a very large long term cost difference when factoring elements such as fuel consumption and maintenance costs.
Regenerative thermal oxidizers can be also applied to destroy wastewater onsite; to learn about the Aqueous Regenerative Thermal Oxidizer, Click Here. Gulf Coast Environmental Systems continues to be one of the most trusted customized pollution control equipment providers in the world.

These drawbacks include: High electrical costs Larger real estate footprint Weight spec that can be up to three times that of a recuperative oxidizer Multi-Canister Systems: Gulf Coast Environmental Systems offers additional, though less common sizing options. A digital controller, allowing proper maintained temperature control Weatherproof, high-density steel enclosure, allowing the processing of highly concentrated exhaust streams Modulating burner Typical sizing from to 60, SCFM Available Options: Custom built, turnkey systems Adjustable stacks, and multi-bed configurations Option of force, or induced, draft fan arrangements Designs available, for smaller or restricted spaces A variety of material options, to withstand corrosive and high temperature exhaust streams Primary and secondary heat recovery systems Control panels, that are built in-house Aqueous RTO — Patent pending proprietary technology Scrubber Carbon Absorbers Quench Rotor Concentrator Multi-Layer Media: Regenerative Thermal Oxidizers RTO Heat Recovery Media GCES has performed dozens of products tests over the years comparing everything from media to wire to ensure our pollution control equipment operates with consistency, efficiency and accuracy.
Benefits of a retrofit include: Reduced Operating Costs: Replacing media can raise thermal efficiency and reduce RTO fuel consumption providing a potentially rapid payback. Previous Next. Pollutant Destruction Phase 1. Inlet switch valves direct the pollutant-laden air into one of the energy recovery canisters. The pollutant is destroyed while in the combustion chamber. The Clean Air Cycle 6. The dirty air from the last inlet bed has to be cleaned out in order to achieve high destruction efficiency.
