The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in the urban area of Lhasa City, Tibet are as follows: kitchen waste 20.45%, paper 23.74%, rubber 14.84%, textiles (fibers) 4.5%, wood and bamboo 2.76%, ash and soil 22.83%, bricks, tiles, and ceramics 0%, glass 4.73%, metals 5.12%, and others 0%. It has a moisture content of 40.98%, higher calorific value of 6798.41 kJ/kg, and lower calorific value of 5207 kJ/kg. 98 kJ/kg. Waste treatment activities are based on an average urban/municipal waste mixture and are not suitable for specific individual wastes 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, after recovering precious metals, are landfilled. The fly ash is solidified at a ratio of 1:1 with cement. The average heat efficiency of waste heat power generation is 22%. In the process of waste heat supply, as no conversion between different forms of heat and energy is involved, the heat efficiency is relatively high, averaging 64%. Through a comprehensive calculation of the heat 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.
