The characteristics of the urban solid waste processed by the municipal solid waste incinerator (MSWI) in Shangrao City, Jiangxi Province are as follows: food waste 67.53%, paper 2.6%, rubber 3.33%, textiles (fiber) 7.4%, wood and bamboo 1.93%, ash and soil 1.47%, bricks, tiles, and ceramics 0%, glass 4.13%, metals 1.2%, and others 10.4%. Moisture content is 56.38%, with higher calorific value of 4214.45 kJ/kg, and lower calorific value of 2400 kJ/kg. 45 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. Each kg of this type of waste generates 0.205 kg of slag and 0. Fly ash and slag, at 05kg, after precious metal recovery are landfilled. The fly ash is solidified with cement in a 1:1 ratio. The average heat efficiency of waste heat power generation is taken as 22%; during the supply of waste heat, no different types of heat and energy conversion occurred, so the heat efficiency is relatively high, averaging 64%; by synthesizing the heat efficiency of the 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.
