The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in Inner Mongolia are as follows: food waste 36.11%, paper 19.41%, rubber 14.35%, textiles (fibers) 5.73%, wood and bamboo 3.87%, ash and soil 10.56%, brick, tile, and ceramics 2.11%, glass 2.89%, metals 2.64%, and others 2.35%. It has a moisture content of 48.12%, higher calorific value of 7088.35 kJ/kg, and lower calorific value of 5320 kJ/kg. 43 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture, not suitable for individual specific waste 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. The fly ash and slag, after precious metal recovery, are landfilled, with a ratio of 1:1 for stabilization with cement. The average thermal efficiency of waste heat power generation is taken as 22%; in the waste heat power supply process, there is no conversion of different forms of heat and energy, so the thermal efficiency is higher, with an average value of 64%. By combining the thermal efficiency of the comprehensive waste heat power generation process and the direct heat supply process, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.
