The characteristics of urban solid waste processed by the Municipal Solid Waste Incinerator (MSWI) in the urban area of Shantou City, Guangdong Province, are as follows: food waste 53.62%, paper 8.7%, rubber 25.17%, textiles (fibers) 8.39%, wood and bamboo 2.25%, ash and soil 0%, brick, tile, and ceramics 0%, glass 0.76%, metals 1.1%, and others 0%. The moisture content is 56%, higher calorific value of 8459.3 kJ/kg, and lower calorific value of 6434 kJ/kg. 37 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific wastes such as plastic, 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. Fly ash and slag, at a rate of 05kg, are subjected to precious metal recovery before being landfilled. Fly ash is mixed with cement 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, thus the heat efficiency is relatively high, taken as an average of 64%; by comprehensively considering the heat efficiency of waste heat power generation and direct heat supply, 15% of the heat generated from the incineration of waste is used for power generation, and 56% is used for direct heating.
