The characteristics of municipal solid waste (MSW) processed by the Municipal Solid Waste Incinerator (MSWI) in the urban area of Yiyang City, Hunan Province are as follows: kitchen waste 43.03%, paper 7.39%, rubber 14.14%, textile (fiber) 3.94%, wood and bamboo 2.15%, ash and soil 1.79%, brick, tile, and ceramics 2.53%, glass 2.7%, metal 1.77%, and other categories 20.57%. The moisture content is 48.88%, higher calorific value of 6164.54 kJ/kg, and lower calorific value of 4505. 17 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 plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please inventory the corresponding waste separately. Each kg of this waste will produce 0.205 kg of slag and 0. The fly ash and slag, after the recovery of precious metals, are landfilled. The fly ash is solidified with cement in a 1:1 ratio. The average heat efficiency of waste heat power generation is 22%; the heat efficiency in the process of waste heat supply is relatively high at an average of 64%, as no different forms of heat and energy conversion occur during the heat supply process; through a comprehensive look at the heat efficiency of both waste heat power generation and direct heat supply processes, 15% of the heat generated in the waste incineration process is used for power generation, and 56% is used for direct heating.
