Regenerative Thermal Oxidation (RTO)

Regenerative Thermal Oxidation (RTO) is a technology designed to treat volatile organic compounds (VOCs), carbon monoxide (CO), nuisance odors and hazardous air pollutants (HAPs). It uses high-temperature oxidation, typically around 800–950°C, to break down suitable organic pollutants, achieving treatment efficiencies of up to 98–99% under appropriate design and operating conditions.

The system combines this process with high-efficiency ceramic heat-recovery media, which can recover more than 95% of the thermal energy for reuse. This helps minimize heat loss and reduce fuel consumption. For suitable applications, RTO provides a robust solution that combines high pollutant-destruction performance with energy-efficient operation.

How It Works

RTO cutaway: ceramic media pre-heating, combustion chamber, heat recovery
  1. Preheating: Waste gas containing VOCs and odors is directed through a pre-heated Ceramic Layer. This process effectively raises the gas temperature, bringing it close to the combustion point.
  2. Oxidation: Upon entering the Combustion chamber, the VOCs and odors undergo complete Oxidative Decomposition. This chemical reaction fully breaks down the pollutants into non-toxic gases.
  3. Heat Recovery: The treated, clean air flows through the outlet ceramic layer to transfer and store thermal energy within the media (to heat the incoming air for the next cycle). Finally, it is released into the atmosphere as Harmless & Clean Gas, free from both color and odor.
  4. Cycle Operation: The system operates by continuously switching the airflow direction (Cycle) between the heat storage and heat release zones to ensure maximum energy efficiency is achieved.

The New Generation Valve System: Eliminating Weaknesses Leakage

We have overcome the limitations of conventional Rotary RTOs, which frequently suffer from Gas Leaks due to seal deterioration and thermal distortion of the rotating structure. We have advanced to 'Valve Type' technology, replacing the air switching mechanism with a high-precision valve system, reinforced by a far more durable Integrated Structure."
