The characteristics of urban solid waste processed by the Municipal Solid Waste Incinerator (MSWI) in the urban area of Nayong County, Guizhou are as follows: kitchen waste 7.71%, paper 12.95%, rubber 12.85%, textile (fiber) 9.66%, wood bamboo 6.71%, ash soil 6.61%, brick and tile ceramics 11.27%, glass 5.94%, metal 5.36%, and other 19.8%. It has a moisture content of 35.2%, higher heating value of 6675.57 kJ/kg, and lower heating value of 5336 kJ/kg. 92 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific waste materials such as plastics, paper, cardboard, etc. If your waste consists of a specific waste mixture, please itemize the corresponding waste separately. Each kg of this waste generates 0.205 kg of slag and 0. The飞ash and furnace slag, at 05kg, are processed for precious metal recovery before being landfilled. The 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, there is no conversion between different forms of heat and energy, so the heat efficiency is relatively high, with an average value of 64%; by comprehensively considering 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.
