The characteristics of the urban solid waste processed by the Municipal Solid Waste Incinerator (MSWI) in the city area of Maoming City, Guangdong Province, are as follows: kitchen waste 55.6%, paper 4.81%, rubber 11.6%, textile (fiber) 13.9%, wood and bamboo 5.54%, ash and soil 0%, brick, tile and ceramics 0.58%, glass 5.23%, metal 2.75%, and other 0%. The moisture content is 53.98%, the higher calorific value of 6411.08 kJ/kg, and the lower calorific value of 4528. 36 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for individual specific waste materials such as plastic, paper, cardboard, etc. If your waste is a specific waste mixture, please inventory the corresponding waste separately. For each kg of this waste, 0.205 kg of slag and 0... The fly ash and slag, after precious metal recovery, are landfilled, with a ratio of 1:1 for fixation with cement. The average thermal efficiency of waste heat power generation is 22%; there is no conversion between different forms of heat and energy during waste heat supply, so the thermal efficiency is relatively high, with an average of 64%; Through the comprehensive thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated in the waste incineration process is used for power generation, and 56% is used for direct heating.
