The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in the urban area of Guangdong Province are as follows: food waste 47.75%, paper 13.66%, rubber 13.91%, textiles (fibers) 10.28%, wood and bamboo 2.86%, ash and soil 5.82%, bricks, tiles, and ceramics 3.55%, glass 1.72%, metals 0.65%, and others 0%. The moisture content is 53.1%, the higher calorific value of 7367.65 kJ/kg, and the lower calorific value of 5459. 2 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for specific types of 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. Fly ash and furnace slag, after the recovery of precious metals, are landfilled. Fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is 22%; during the waste heat supply process, no different forms of heat and energy conversion have been performed, so the heat efficiency is higher, with an average of 64%; comprehensively considering 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.
