Description
Technical Field

[0002] The principle of RTO waste gas treatment is to oxidize the combustible waste gas (containing volatile organic compounds) into corresponding oxides and water at high temperature, thereby purifying the waste gas and recovering the heat released when the waste gas is decomposed. The waste gas decomposition efficiency is high and the heat recovery efficiency is high. Most volatile organic compounds have a special unpleasant odor and are toxic, irritating, teratogenic and carcinogenic. In particular, benzene, toluene and formaldehyde can cause great harm to human health. Volatile organic compounds are important precursors to urban haze and photochemical smog.
