The characteristics of urban solid waste processed by the Municipal Solid Waste Incinerator (MSWI) in the rural area of Shenyang City, Liaoning Province, are as follows: kitchen waste 19.37%, paper 1.92%, rubber 2.08%, textile (fiber) 0.22%, wood and bamboo 0.16%, ash and soil 74.6%, bricks, tiles and ceramics 0.42%, glass 0.65%, metals 0.38%, and other 0.23%. The moisture content is 37.42%, higher calorific value of 4812.03 kJ/kg, and lower calorific value of 3424. 9 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture 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. Each kg of this waste will produce 0.205 kg of slag and 0. The fly ash and slag, at a proportion of 05kg, are subjected to precious metal recovery before landfilling, with a 1:1 fixation treatment with cement. The average heat efficiency of waste heat power generation is taken as 22%; during the process of waste heat supply, there are no different forms of heat and energy conversion, so the heat efficiency is higher, averaging 64%. By comprehensively considering 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.
