The characteristics of urban solid waste processed by the municipal solid waste incinerator (MSWI) in the rural areas of Lhasa City, Tibet are as follows: kitchen waste 12.77%, paper 10.73%, rubber 20.77%, textile (fiber) 5.91%, wood and bamboo 10.26%, ash and soil 33.12%, brick, tile and ceramics 2.04%, glass 1.83%, metal 1.54%, others 0%. Moisture content is 40.02%, higher calorific value of 7914.76 kJ/kg, lower calorific value of 6292 kJ/kg. 39 kJ/kg. Waste treatment activities are based on an average urban/municipal waste mixture and are not suitable for single specific waste items 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. The fly ash and slag, after precious metal recovery, are landfilled, with a ratio of 1:1 for solidification treatment with cement. The average heat efficiency of waste heat power generation is 22%; in the process of waste heat supply, there is no conversion between different forms of heat and energy, so the heat efficiency is higher, with an average of 64%. Through the comprehensive heat efficiency of the waste heat power generation process and the direct heat supply process, 15% of the heat generated by waste incineration is used for power generation, and 56% is used for direct heating.
