The characteristics of urban solid waste processed by the municipal solid waste incinerator (MSWI) in the rural area of Mianyang City, Sichuan Province, are as follows: kitchen waste 65.17%, paper 10.28%, rubber 7.4%, textile (fiber) 10.13%, wood and bamboo 2.6%, ash soil 0%, brick and tile ceramics 0.06%, glass 0.86%, metal 0.44%, and others 1.62%. It has a moisture content of 58.2%, higher calorific value of 5936.53 kJ/kg, and lower calorific value of 3966. 86 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 plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please itemize the corresponding waste separately. For each kg of this type of waste, 0.205 kg of slag and 0. The fly ash and slag, at a ratio of 05kg, are subjected to precious metal recovery before being landfilled. For solidification treatment, the fly ash is mixed with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is taken as 22%; in the process of waste heat supply, there is no conversion between different forms of heat and energy, resulting in a higher heat efficiency, averaged at 64%. Through a comprehensive analysis of the thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.
