The characteristics of urban solid waste processed by the Municipal Solid Waste Incinerator (MSWI) in Hezhang County, Guizhou, are as follows: kitchen waste 11.99%, paper 24.93%, rubber 47.99%, textile (fiber) 4.73%, wood and bamboo 1.1%, ash and soil 0%, brick, tile, and ceramics 3.45%, glass 0.79%, metal 0.35%, and other 4.65%. Moisture content is 44.81%, with higher calorific value of 11537.16 kJ/kg and lower calorific value of 9628 kJ/kg. 61 kJ/kg. Waste treatment activities are based on an average urban/municipal waste mixture and are 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. Each kg of this waste will produce 0.205 kg of slag and 0. Fly ash and slag, at a ratio of 0.5 kg, after precious metal recovery, are landfilled.Fly ash and cement are solidified in a 1:1 ratio. The average heat efficiency of waste heat power generation is 22%; the waste heat supply does not involve different forms of heat and energy conversion, so the heat efficiency is relatively high, which is 64% on average; through the comprehensive heat efficiency of waste heat power generation and direct heat supply processes, 15% of the heat generated in the waste incineration process is used for power generation, and 56% is used for direct heating.
