The characteristics of the urban solid waste processed by the Municipal Solid Waste Incinerator (MSWI) in the urban area of Dalian City, Liaoning Province, are as follows: food waste 57.02%, paper 2.96%, rubber 11.54%, textiles (fibers) 2.36%, wood and bamboo 1.85%, ash and soil 16.82%, bricks, tiles, and ceramics 2.73%, glass 3.66%, metals 1.06%, and others 0%. It has a moisture content of 52.96%, and higher calorific value of 5156. 01 kJ/kg, lower heating value 3340 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture, not suitable for individual specific waste such as 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. The fly ash and slag, after precious metal recovery, are landfilled. The fly ash is solidified with cement at a ratio of 1:1. Waste heat power generation has an average thermal efficiency of 22%; the waste heat used directly for heat supply has a higher efficiency without conversion between different forms of heat and energy, with an average efficiency of 64%; through the comprehensive consideration of the thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated during waste incineration is used for power generation, and 56% is used for direct heating.
