The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in the urban area of Suzhou City, Jiangsu Province, are as follows: food waste 42.18%, paper 11.86%, rubber 0%, textiles (fibers) 5.79%, wood and bamboo 1.7%, ash and soil 0%, bricks, tiles, and ceramics 0.64%, glass 1.69%, metals 0.9%, and others 35.69%. The moisture content is 48%, higher calorific value of 5051.51 kJ/kg, lower calorific value of 3540 kJ/kg. 08 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific types of waste 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, at a rate of 05kg, are subjected to precious metal recovery and then landfilled. Fly ash is solidified with cement at a ratio of 1:1. The average thermal efficiency of waste heat power generation is taken as 22%; during the process of waste heat supply, there is no conversion between different forms of heat and energy, so the thermal efficiency is higher, at an average of 64%; by synthesizing 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.
