The characteristics of urban solid waste processed by the municipal solid waste incinerator (MSWI) in the rural areas of Hainan Province are as follows: kitchen waste 54.12%, paper 10.76%, rubber 10.1%, textile (fiber) 0.18%, wood and bamboo 2.98%, ash and soil 0%, brick, tile, and ceramics 2.08%, glass 5%, metal 0.53%, and others 14.53%. It has a moisture content of 52.41%, higher calorific value of 5256.42 kJ/kg, and lower calorific value of 3514. 35 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. For this type of waste, every kg will produce 0.205 kg of slag and 0. The fly ash and slag, after the recovery of precious metals, are landfilled. Fly ash is treated with cement at a ratio of 1:1 for solidification. The average heat efficiency of waste heat power generation is 22%. In the process of waste heat supply, no different forms of heat and energy conversion are used, so the heat efficiency is higher and the average value is 64%. Through a comprehensive look at the heat efficiency of the waste heat power generation process and direct heat supply, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.
