The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in Ningxia are as follows: food waste 35.7%, paper 2.1%, rubber 4.1%, textiles (fibers) 1.2%, wood and bamboo 1.7%, ash and soil 0%, brick, tile, and ceramics 45.7%, glass 0.4%, metals 0.2%, and others 8.9%. It has a moisture content of 55.81%, higher calorific value of 4907.39 kJ/kg, and lower calorific value of 3368. 45 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 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, at a weight of 05kg, are subjected to precious metal recovery before being landfilled, with a 1:1 solidification treatment of fly ash and cement. The average heat efficiency of waste heat power generation is taken as 22%; in the waste heat supply process, no different forms of heat and energy conversion are carried out, so the heat efficiency is higher, averaging 64%; by integrating the thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated from waste incineration is used for power generation and 56% for direct heating.
