The characteristics of urban solid waste processed by the MSWI (Municipal Solid Waste Incinerator) in Heilongjiang are as follows: food waste 55.73%, paper 15.71%, rubber 17.98%, textile (fiber) 5.29%, wood and bamboo 2.54%, ash and soil 0%, bricks, tiles, and ceramics 0%, glass 2.36%, metal 0.4%, and others 0%. It has a moisture content of 56.12%, higher calorific value of 7409.11 kJ/kg, and lower calorific value of 5419. 33 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific waste like plastic, 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. 05kg of fly ash and slag, after the recovery of precious metals, are landfilled. The 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%; the waste heat supply process does not involve the conversion of different forms of heat and energy, so the heat efficiency is higher, with an average value of 64%; through the comprehensive thermal efficiency of residual heat power generation and direct heat supply, 15% of the heat generated by the waste incineration process is used for power generation, and 56% is used for direct heating.
