The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in the urban area of Chengdu city, Sichuan province, are as follows: food waste 47.06%, paper 15.76%, rubber 14.98%, textiles (fibers) 1.72%, wood and bamboo 0%, ash and soil 6.45%, bricks, tiles, and ceramics 0.97%, glass 0.73%, metal 1.01%, and others 11.32 %. The moisture content is 51.79%, higher calorific value of 6603.02 kJ/kg, and lower calorific value of 4802. 8 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for single 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. The fly ash and 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 22%; in the process of waste heat supply, there is no conversion of different forms of heat and energy, so the heat efficiency is higher, taken as an average of 64%; through the comprehensive thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated in the waste incineration process is used for power generation, and 56% is used for direct heating.
