The characteristics of municipal solid waste treated by the municipal solid waste incinerator (MSWI) in the urban area of Zhongshan City, Guangdong Province, are as follows: food waste 44.87%, paper 13.35%, rubber 25.34%, textile (fiber) 7.5%, wood bamboo 4.93%, ash soil 0.68%, brick tile ceramics 0.38%, glass 1.84%, metal 1.12%, and other 0%. It has a moisture content of 53.25%, higher heating value of 8712.01 kJ/kg, and lower heating value of 6739. 26 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific waste materials such as plastic, paper, cardboard, etc. If your waste consists of a specific waste mixture, please separately account for the corresponding waste. Each kg of this waste will produce 0.205 kg of slag and 0.  Fly ash and slag are subjected to precious metal recovery before being landfilled, with a ratio of 1:1 for solidification treatment with cement. The average thermal efficiency of waste heat power generation is taken as 22%; the waste heat supply process does not involve different forms of heat and energy conversion, resulting in a relatively higher thermal efficiency, averaging 64%; Through a comprehensive process of waste heat power generation and direct heating, 15% of the heat generated in the waste incineration process is used for power generation, and 56% is used for direct heating.
