The characteristics of urban solid waste processed by Qinghai city's municipal solid waste incinerator (MSWI) are as follows: food waste 47.78%, paper 6.85%, rubber 9.41%, textile (fiber) 2.72%, wood and bamboo 1.75%, ash and soil 0%, bricks, tiles, and ceramics 27.22%, glass 2.89%, metal 1.21%, and others 0.17%. Moisture content is 55.81%, higher calorific value of 5367.35 kJ/kg, and lower calorific value of 3624. 71 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for individual specific wastes 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 landfilled after precious metal recovery; fly ash and cement are solidified at a ratio of 1:1. The average heat efficiency of waste heat power generation is taken as 22%; during the waste heat supply process, there is no different form of heat and energy conversion, resulting in a relatively high thermal efficiency, averaging 64%; through a comprehensive analysis of the waste heat power generation process and direct heating process, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.
