The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in the city area of Pu'er City, Yunnan Province, are as follows: food waste 47.27%, paper 10.34%, rubber 16.14%, textile (fiber) 9.27%, wood and bamboo 5.61%, ash and soil 0%, bricks, tiles, and ceramics 1.06%, glass 8.91%, metal 1.4%, and others 0%. The moisture content is 50.84%, higher calorific value of 6682.44 kJ/kg, and lower calorific value of 4858.44 kJ/kg. 98 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for individual specific waste such as plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please inventory the corresponding waste separately. For this type of waste, 0.205 kg of slag is generated per kg of waste and 0. Fly ash and slag, at a quantity of 05kg, are subjected to precious metal recovery before landfilling, and 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 heat efficiency of waste heat power generation and direct heat supply processes, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.
