The characteristics of urban solid waste processed by the municipal solid waste incinerator (MSWI) in the urban area of Meizhou City, Guangdong Province, are as follows: food waste 38.76%, paper 34.85%, rubber 17.35%, textile (fiber) 0.34%, wood and bamboo 0.99%, ash and soil 0%, brick, tile and ceramics 0%, glass 4.46%, metal 3.25%, and other wastes 0%. The moisture content is 49.9%, the higher calorific value is 7393.28 kJ/kg, and the lower calorific value is 5546. 36 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture, not suitable for single 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. Fly ash and slag are landfilled after precious metal recovery, with a ratio of 1:1 for solidification treatment with cement. The average thermal efficiency of waste heat power generation is 22%; the waste heat supply process does not involve different forms of heat and energy conversion, so the thermal efficiency is relatively high, at an average of 64%; considering the comprehensive thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated from waste incineration is used for power generation, and 56% is used for direct heating.
