[0002] In daily life, municipal solid waste incineration is the process of treating municipal solid waste through incineration. Incineration is a high-temperature thermal treatment technology in which a certain amount of excess air reacts with the organic waste being treated in an incinerator to carry out an oxidative combustion reaction. Harmful and toxic substances in the waste are destroyed through oxidation and pyrolysis at high temperatures of 800℃ to 1200℃. It is a treatment technology that can simultaneously achieve waste detoxification, volume reduction, and resource recovery. The purpose of incineration is to burn waste as much as possible, making the incinerated materials harmless and reducing their volume to the maximum extent, while minimizing the generation of new pollutants and avoiding secondary pollution.
