The principle of RTO is to heat the organic waste gas to above seven hundred sixty degrees centigrade to oxidize and decompose the VOC in the waste gas into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a specially-made ceramic heat accumulator to heat the ceramic body so as to realize heat accumulation, and the heat accumulation is used for preheating the subsequently entering organic waste gas. Thereby saving fuel consumption for exhaust gas temperature rise. The ceramic heat storage chambers are divided into more than two, and each heat storage chamber sequentially undergoes heat storage, heat release, cleaning and other procedures, and works repeatedly and continuously. The main structure of the RTO consists of a combustion chamber, a regenerator, a switching valve and the like.
