[0003] Incineration is currently one of the main methods for treating urban domestic waste. However, due to the particularity of urban domestic waste, the following problems usually occur when using incinerators for incineration: (1) Due to the high water content of urban domestic waste, a large amount of water contained in it will be converted from liquid to gas, which will reduce the temperature of the incinerator, thereby increasing the energy consumption of waste incineration and the cost of waste incineration; in addition, urban domestic waste with high water content is difficult to burn fully in the incinerator, and a large amount of carbon monoxide will be produced during combustion, thereby increasing the difficulty and cost of treating the exhaust gas generated by waste combustion. (2) Due to the complex sources of urban domestic waste, it contains waste of various sizes and shapes. Therefore, small-volume debris is easy to burn during incineration, while large-volume waste is difficult to burn, which makes it difficult for urban domestic waste to burn evenly.
