The characteristics of urban solid waste processed by the MSWI (Municipal Solid Waste Incinerator) in the urban area of Hainan Province are as follows: food waste 47.44%, paper 5.94%, rubber 12.46%, textiles (fibers) 1.92%, wood bamboo 0%, ash soil 0%, brick tiles ceramics 6.53%, glass 2.84%, metal 2.56%, and other categories 20.31%. The moisture content is 49.33%, higher calorific value of 5411.94 kJ/kg, and lower calorific value of 3772 kJ/kg. 93 kJ/kg. Waste treatment activities are based on an average urban/municipal waste mixture and are not suitable for single specific waste materials like plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please inventory the corresponding waste separately. Each kg of this waste generates 0.205 kg of slag and 0. The fly ash and slag, at a rate of 05kg, after precious metal recovery are landfilled. The fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is taken as 22%; in the process of waste heat supply, no different forms of heat and energy conversion have been performed, the heat efficiency is higher, with an average value of 64%; by combining the thermal efficiency of waste heat power generation 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.
