The characteristics of municipal solid waste processed by the municipal solid waste incinerator (MSWI) in the urban area of Ganzhou City, Jiangxi Province, are as follows: food waste 25.2%, paper 18.78%, rubber 0%, textiles (fibers) 4.46%, wood and bamboo 5.2%, ash and soil 0%, bricks, tiles and ceramics 0%, glass 6.35%, metals 2.02%, and others 37.99%. It has a moisture content of 41.04%, higher heating value of 5244.78 kJ/kg, and lower heating value of 3915. 37 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. Every kg of this waste will produce 0.205 kg of slag and 0. Fly ash and slag are subjected to precious metal recovery before being landfilled, with a ratio of 1:1 for fly ash and cement solidification treatment. The average heat efficiency of waste heat power generation is 22%; during the process of waste heat supply, there is no conversion between different forms of heat and energy, so the heat efficiency is high, with an average value of 64%. Through a comprehensive analysis of the thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.
