RTO refers to Regenerative Thermal Oxidizer (RTO), also known as regenerative thermal burner, or regenerative combustion device. The core component of RTO is regenerative ceramic, which is installed in the regenerative chamber of the regenerative combustion device. Generally, a combined honeycomb or honeycomb ceramic regenerative body is used as the main regenerative material, a rectangular saddle ring is used as a supporting covering protective material, and a regenerative ceramic ball is used as a gap filling and supporting protective material, which are used in combination with each other; it is widely used in various types of organic waste gas purification in the petroleum, chemical and natural gas processing industries, rubber production industries, pharmaceutical and food processing industries, and painting and printing industries. RTO technology usually has two-chamber RTO, three-chamber RTO and rotary RTO, and can also be designed into five-chamber RTO, seven-chamber RTO and other structural forms according to needs.

RTO technology: The system heats the organic waste gas to above 760℃ and keeps it in the high-temperature heat storage furnace for more than 0.75s. The organic waste gas undergoes oxidation reaction and oxidizes the hydrocarbons in the waste gas into CO₂ and H₂O, which are then discharged into the atmosphere after being purified and meet the standards. At the same time, since the RTO device has a set of good heat storage ceramic packed beds with a heat recovery rate of more than 95%, the high-temperature flue gas generated after oxidation can be stored in heat through the heat storage ceramics, so that the furnace chamber is always maintained at a very high operating temperature. Therefore, only a small amount of fuel is consumed during the treatment process, or even no fuel is consumed. When the concentration is higher, heat can be exported to the outside for secondary heat recovery. At the same time, the dual goals of energy saving (saving fuel consumption for preheating and heating of waste gas) and environmental protection (VOCs purification) are achieved.
