The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in the urban area of Qingdao City, Shandong Province, are as follows: food waste 69%, paper 9.5%, rubber 8.4%, textile (fiber) 3%, wood and bamboo 0.3%, ash and soil 6.3%, brick and ceramic 0.3%, glass 2.2%, metal 0.9%, and others 0.1 %. Moisture content is 58.34%, higher calorific value of 4950.01 kJ/kg, and lower calorific value of 3000 kJ/kg. 06 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. For each kg of this type of waste, 0.205 kg of slag and 0. The fly ash and slag, in a ratio of 0.5kg, undergo precious metal recovery before landfilling, and the fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is taken as 22%; in the process of waste heat supply, there is no conversion of different forms of heat and energy, so the heat efficiency is relatively high, at an average of 64%; through a comprehensive analysis of the heat efficiency of waste heat power generation and direct heat supply, 15% of the heat generated during waste incineration is used for power generation, and 56% is used for direct heating.
