The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in Yunnan urban are as follows: food waste 50.65%, paper 13.98%, rubber 17.04%, textiles (fibers) 5.16%, wood and bamboo 6.68%, ash and soil 0%, bricks, tiles, and ceramics 0.32%, glass 4.02%, metals 1.26%, and other wastes 0%. It has a moisture content of 53.45%, higher heating value of 7089.1 kJ/kg, and lower heating value of 5179 kJ/kg. 22 kJ/kg. Waste treatment activities are based on an average urban/public waste mix and are not suitable for individual specific wastes such as plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please inventory the corresponding waste separately. For each kg of this waste, 0.205 kg of slag and 0. Fly ash and furnace slag, after the recovery of precious metals, 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 22%; the waste heat supply process does not involve different types of heat and energy conversion, thus it has a higher heat efficiency at the average value of 64%. Through the comprehensive waste heat power generation process and direct heat supply, 15% of the heat generated from waste incineration is used for power generation, and 56% is used for direct heating.
