Working Principle
The rotary RT0 mainly consists of a combustion chamber, ceramic packing bed, and rotary valves, etc. The furnace body is divided into 12 ceramic packing beds, 5 inlet chambers (preheating zone), 5 outlet chambers (cooling zone), 1 purge chamber, and 1 isolation chamber. The waste gas enters the preheating zone through the intake distributor, and after being preheated to a certain temperature, it enters the top combustion chamber for complete oxidation and decomposition. The purified high-temperature gas leaves the combustion chamber and enters the cooling zone to transfer heat to the ceramic energy storage material, and the gas is cooled and expelled through the gas distributor. The ceramic energy storage material in the cooling zone absorbs the heat and stores a large amount of energy for heating the exhaust gas in the next cycle. In this way, the waste gas is alternately oxidized and decomposed in the combustion chamber. When the VOC concentration in the exhaust gas is above a certain value and the heat released from the oxidative decomposition is sufficient to maintain the reaction temperature of the combustion chamber, there is no need to use fuel to heat it, thus improving the utilization of energy cycling.

Selection Criteria
1. It is necessary to specifically indicate during selection if the exhaust gas contains corrosive components such as sulfur and chlorine, and SUS2205 or higher corrosion-resistant materials need to be used for such gases. The material processing and manufacturing must also include special treatment for these gases in the latter stage.
2. The mixed waste gas entering the heat storage type high-temperature incineration equipment should have a concentration range of less than 1/4 of the lower explosive limit (LEL).
3. The maximum temperature used for heat storage type high-temperature incinerators is lower than 960℃. High heat substances and highly concentrated gases need to undergo dilution treatment, and if there are special requirements, they should be specified to ensure specific insulation requirements during design.
4. The gas entering the heat storage type high-temperature incineration equipment must not contain dust particles or oil mist that could cause clogging or bowing/reheating, to prevent reheating and blockage of the heat storage ceramic.
5. For some regions with requirements on nitrogen oxides emissions from high-temperature incineration equipment outlets, it needs to be specifically indicated, so that low nitrogen combustion systems can be selected when purchasing combustion engines. Additionally, even if low nitrogen combustion systems are used, if the waste gas contains a high concentration of nitrogen components that fail to meet the emissions standards, subsequent denitrification treatment is required.
