The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in Hubei city are as follows: food waste 55.3%, paper 1.5%, rubber 4.5%, textiles (fibers) 0%, wood/bamboo 8.3%, ash/soil 0%, brick/ceramics 27.3%, glass 2%, metals 1.1%, and others 0%. Moisture content is 52.18%, higher calorific value of 4550.7 kJ/kg, and lower calorific value of 2783 kJ/kg. 55 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 separately account for the corresponding waste. Each kg of this waste will produce 0.205 kg of slag and 0. The fly ash and slag, at a ratio of 0.5kg, are treated for precious metal recovery before being landfilled. Fly ash is solidified 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, so the heat efficiency is higher, taken as an average of 64%; through a comprehensive consideration of the thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated in the waste incineration process is used for power generation, and 56% is used for direct heating.
