The working principle of RTO waste gas treatment equipment is to heat organic waste gas to above 760 ℃, causing VOC in the waste gas to oxidize and decompose 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". This "heat storage" is used to preheat the subsequent organic waste gas entering. Thus saving fuel consumption for exhaust gas heating. Ceramic heat storage bodies should be divided into two or more zones or chambers, each of which undergoes a sequence of heat storage, heat release, and cleaning procedures, repeating the cycle and working continuously. After the heat storage chamber releases heat, an appropriate amount of clean air should be introduced immediately to clean the chamber. Only after the cleaning is completed can the "heat storage" program be entered.

阶段一：废气通过蓄热床A被预热，然后进入燃烧室燃烧，蓄热床C中残留未处理废气被净化后的气体反吹回燃烧室进行焚烧处理（吹扫功 能），分解后的废气经过蓄热床B排出，同时蓄热床B被加热。

Stage 1: The exhaust gas is preheated through the heat storage bed A and then enters the combustion chamber for combustion. The remaining untreated exhaust gas in the heat storage bed C is purged back into the combustion chamber for incineration treatment (blowing function). The decomposed exhaust gas is discharged through the heat storage bed B, while the heat storage bed B is heated.

阶段二：废气通过蓄热床B被预热，然后进入燃烧室燃烧，蓄热床A中残留未处理废气被净化后的气体反吹回燃烧室进行焚烧处理，分解后废气经过蓄热床C排出，同时蓄热床C被加热。

Stage 2: The exhaust gas is preheated through the heat storage bed B and then enters the combustion chamber for combustion. The remaining untreated exhaust gas in the heat storage bed A is purged back into the combustion chamber for incineration treatment, and the decomposed exhaust gas is discharged through the heat storage bed C, while the heat storage bed C is heated.

阶段三：废气通过蓄热床C被预热，然后进人燃烧室燃烧，蓄热床B中残留未处理废气被净化后的气体反吹回燃烧室进行焚烧处理分解后废气经过蓄热床A排出，同时蓄热床A被加热。

Stage 3: The exhaust gas is preheated through the heat storage bed C, and then enters the combustion chamber for combustion. The remaining untreated exhaust gas in the heat storage bed B is purged back into the combustion chamber for incineration treatment. After decomposition, the exhaust gas is discharged through the heat storage bed A, and at the same time, the heat storage bed A is heated.

如此周期性运行，废气在燃烧室内氧化分解，燃烧室内温度维持在设定温度（一般为800～850℃）。当RTO进气口的废气浓度达到一定值时，VOCs氧化释放的热量能够维持RTO蓄热和放热的能量储备，则此时RTO不需要使用燃料就能够维持燃烧室内的温度。

In such periodic operation, the exhaust gas oxidizes and decomposes in the combustion chamber, and the temperature in the combustion chamber is maintained at the set temperature (usually 800~850 ℃). When the concentration of exhaust gas at the RTO inlet reaches a certain value, the heat released by VOCs oxidation can maintain the energy reserve for RTO heat storage and release. At this time, RTO can maintain the temperature of the combustion chamber without using fuel.
