The characteristics of municipal solid waste processed by the Municipal Solid Waste Incinerator (MSWI) in the urban area of Dongguan City, Guangdong Province, are as follows: food waste 51.85%, paper 6.16%, rubber 26.21%, textile (fiber) 9.26%, wood and bamboo 3.73%, ash and soil 0%, bricks, tiles, and ceramics 0%, glass 1.53%, metal 1.25%, and others 0%. Moisture content is 55.21%, higher calorific value of 8534.26 kJ/kg, and lower calorific value of 6526. 49 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for individual specific waste 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. The fly ash and slag, after the recovery of precious metals, are landfill disposed, with fly ash and cement being solidified at a ratio of 1:1. The average heat efficiency of waste heat power generation is 22%; in the process of waste heat supply, no different forms of heat and energy conversion are carried out, so the heat efficiency is higher, and the average value is 64%; through the comprehensive heat efficiency of waste heat power generation process and direct heat supply process, 15% of the heat generated in the waste incineration process is used for power generation, and 56% is used for direct heating.
