The characteristics of urban solid waste processed by the Jilin city solid waste incinerator (MSWI) are as follows: food waste 43%, paper 4.9%, rubber 15%, textile (fiber) 2.7%, wood and bamboo 2.7%, ash and soil 0%, brick, tile and ceramics 4.6%, glass 2.6%, metal 0.5%, and others 24%. Moisture content is 55.81%, higher calorific value of 6171.51 kJ/kg, and lower calorific value of 4526 kJ/kg. 37 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 waste will produce 0.205 kg of slag and 0. Fly ash and furnace slag, at a weight of 05kg, after precious metal recovery, are landfilled. 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%; during the process of waste heat supply, there is no conversion of different forms of heat and energy, so the heat efficiency is high, with an average value taken as 64%; by comprehensively considering the 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.
