The characteristics of the urban solid waste processed by the municipal solid waste incinerator (MSWI) in the Huizhou city area, Guangdong Province, are as follows: food waste 44.77%, paper 11%, rubber 26.44%, textiles (fibers) 11.06%, wood and bamboo 3.63%, ash and soil 0%, brick, tile and ceramics 0.99%, glass 0.93%, metals 1.17%, and other materials 0%. The moisture content is 53.58%, the higher calorific value of 9112.85 kJ/kg, and the lower calorific value of 7119 kJ/kg. 09 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific waste materials such as plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please inventory the corresponding waste separately. For each kg of this waste, 0.205 kg of slag and 0. The fly ash and slag are subjected to precious metal recovery before being landfilled, with a ratio of 1:1 solidification treatment of fly ash and cement. The average heat efficiency of waste heat power generation is 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, and the average value is 64%; by combining the heat efficiency of waste heat power generation and direct heat supply, 15% of the heat generated by waste incineration is used for power generation, and 56% is used for direct heating.
