Thermal Storage Combustion Equipment (RTO): Thermal Storage Combustion Exhaust Gas Treatment Equipment (RTO) is an organic waste gas treatment equipment. Compared with traditional catalytic combustion and direct combustion thermal oxidation furnaces (TO), it has the characteristics of high thermal efficiency (≥ 95%), low operating costs, and the ability to treat high air volume and low concentration exhaust gases. When the concentration is slightly higher, it can also perform secondary waste heat recovery, greatly reducing production and operating costs. The main structure of RTO consists of a combustion chamber, a heat storage chamber, and a switching valve. According to the actual needs of users, different heat recovery methods and switching valve methods can be selected.

The principle is to heat organic waste gas to above 760 ℃, and VOCs in the waste gas can be oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a specially designed ceramic heat storage body, causing the ceramic body to heat up and store heat, which is used to preheat the incoming organic waste gas. Thus saving fuel consumption for exhaust gas heating. Ceramic heat storage chambers should be divided into two or more (including two), each of which undergoes processes such as heat storage, heat release, and cleaning in sequence, working continuously. After the heat release of the heat storage chamber, an appropriate amount of clean air should be immediately introduced to clean it (ensuring a VOC removal rate greater than 98%) before entering the heat storage process. Otherwise, residual VOCs will be discharged into the chimney along with the flue gas, thereby reducing treatment efficiency.
