The characteristics of urban solid waste processed by the municipal solid waste incinerator (MSWI) in Tibet are as follows: kitchen waste 57%, paper 6%, rubber 12%, textile (fiber) 7%, wood and bamboo 14%, ash soil 0%, brick and tile ceramics 3%, glass 0%, metal 1%, and other 0%. The moisture content is 56.86%, the higher calorific value of 7185.47 kJ/kg, and the lower calorific value of 5196. 19kJ/kg. Waste treatment activities are based on an average urban/public waste mixture, not suitable for individual specific waste such as plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please inventory the corresponding waste separately. For this type of waste, 0.205kg of slag is produced per kg of waste and 0. Fly ash and slag are subjected to precious metal recovery before being landfilled; fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is 22%; during the process of waste heat supply, no different forms of heat and energy conversion have been carried out, so the heat efficiency is higher, taken as an average of 64%. Through a combination of the thermal 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.
