The characteristics of urban solid waste processed by the municipal solid waste incinerator (MSWI) in the urban area of Chongqing city are as follows: kitchen waste 72.97%, paper 9.34%, rubber 8.4%, textile (fiber) 3.16%, wood and bamboo 1.91%, ash and soil 1.48%, brick, tile and ceramics 0.92%, glass 1.46%, metal 0.36%, and other 0%. Moisture content is 60.44%, higher calorific value of 5117.07 kJ/kg, and lower calorific value of 3105. 67 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for individual specific waste such as plastic, 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 are processed in a 1:1 ratio with cement for solidification after the recovery of precious metals, and then they are landfilled. The average thermal efficiency of waste heat power generation is taken as 22%; in the process of waste heat supply, there is no conversion of different forms of heat and energy, so the thermal efficiency is relatively high, averaging 64%. By comprehensively considering the thermal efficiency of waste heat power generation and direct heat supply processes, 15% of the heat generated during waste incineration is used for power generation, and 56% is used for direct heating.
