The characteristics of municipal solid waste processed by the municipal solid waste incinerator (MSWI) in the urban area of Mianyang City, Sichuan Province, are as follows: food waste 60.2%, paper 10.3%, rubber 21.9%, textile (fiber) 3.6%, wood-bamboo 1.01%, ash-soil 1.9%, bricks-tiles-ceramics 0%, glass 0.9%, metal 0%, and others 0.9%. It has a moisture content of 57.9%, and a high calorific value of 7624. 18 kJ/kg, lower heating value 5586 kJ/kg. The waste treatment activity is based on an average urban/municipal waste mixture and is 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. Every kg of this waste will produce 0.205 kg of slag and 0. Fly ash and furnace slag, after the recovery of precious metals, are landfilled. Fly ash and cement are mixed at a ratio of 1:1 for solidification treatment. 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, averaging 64%. Through a comprehensive consideration of the thermal efficiency of the waste heat power generation process and the direct heating process, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.
