The characteristics of the urban solid waste processed by the municipal solid waste incinerator (MSWI) in the urban area of Hechi City, Guangxi Province are as follows: kitchen waste 27.51%, paper 14.15%, rubber 17.68%, textile (fiber) 5.03%, wood and bamboo 6.03%, ash and soil 10.27%, bricks, tiles, and ceramics 0%, glass 8.78%, metal 10.56%, and other 0%. The moisture content is 41.24%, the higher calorific value of 6158.4 kJ/kg, and the lower calorific value of 4601. 5 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 plastic, 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. The 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 of waste heat power generation is taken as 22%; during the process of waste heat supply, there is no conversion between different forms of heat and energy, so the heat efficiency is higher, with an average value of 64%; by synthesizing the thermal efficiency of waste heat power generation and direct heat supply processes, 15% of the heat generated by waste incineration is used for power generation while 56% is used for direct heating.
