RTO Incinerator

RTO (Regenerative Thermal Oxidizer) is an efficient environmental protection device for treating organic waste gases. It decomposes volatile organic compounds (VOCs) into carbon dioxide and water through high-temperature oxidation, achieving a thermal recovery rate of over 95%. It is widely used in industries such as chemical, printing, and pharmaceuticals.
Core Principles and Workflow
High-Temperature Oxidation: Waste gas is heated to 750-800°C in the combustion chamber (oxidation chamber), where VOCs are completely decomposed into harmless CO₂ and H₂O, with a residence time of approximately 1-2 seconds.
Regenerative Heat Recovery: Ceramic regenerative bodies alternately absorb heat from high-temperature gases and preheat incoming waste gas, achieving a thermal recovery rate of over 95%, significantly reducing fuel consumption.
Multi-Chamber Alternation: Typical designs feature two or three chambers, enabling continuous treatment through periodic switching of airflow direction.
Technical Features and Advantages
High Purification Efficiency: VOCs removal rate typically exceeds 95%, with three-chamber RTOs reaching up to 99%.
Energy Efficiency and Economy: No auxiliary fuel is required when waste gas concentration is ≥450 ppm, resulting in low operating costs.
Strong Adaptability: Capable of treating high-volume, low-concentration waste gases and complex VOCs (such as alkanes, aromatic hydrocarbons, etc.).
Application Areas
Industrial Scenarios: Organic waste gas treatment in industries such as chemical, coating, electronics manufacturing, and pharmaceuticals.
Waste Gas Types: Suitable for VOCs including hydrocarbons, ketones, esters, etc., but concentration must be controlled below 25% of the lower explosive limit.
