The characteristics of the municipal solid waste processed by the municipal solid waste incinerator (MSWI) in the urban area of Kunming City, Yunnan Province are as follows: food waste 46.15%, paper 17.24%, rubber 23.68%, textile (fiber) 2.92%, wood and bamboo 5.39%, ash and soil 0%, brick, tile and ceramics 0%, glass 2.46%, metal 2.16%, and others 0%. It has a moisture content of 53.05%, higher heating value of 8086.27 kJ/kg, and lower heating value of 6140. 33 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for specific individual 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. Fly ash and furnace slag, after precious metal recovery, are landfilled. The fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency for waste heat power generation is 22%; since no different forms of heat and energy conversion are carried out during waste heat supply, the heat efficiency is relatively high at an average of 64%. Through a comprehensive analysis of the heat efficiency in the process of waste heat power generation and direct heat supply, 15% of the heat generated during waste incineration is used for power generation, and 56% is used for direct heating.
