The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in the urban area of Liuzhou City, Guangxi Province are as follows: food waste 63.18%, paper 12.01%, rubber 13.96%, textiles (fibers) 1.97%, wood and bamboo 5.6%, ash and soil 0%, bricks, tiles, and ceramics 0%, glass 2.75%, metals 0.53%, and other 0%. The moisture content is 57.78%, the higher calorific value of 6304.65 kJ/kg, and the lower calorific value of 4316. 38 kJ/kg. Waste treatment activities are based on an average urban/municipal 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 separately account for the corresponding waste. For each kg of this type of waste, 0.205 kg of slag and 0. The fly ash and slag, at a rate of 05kg, are subjected to precious metal recovery before landfilling, and the fly ash is solidified with cement at a ratio of 1:1. The average value for the thermal 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 thermal efficiency is high and the average value is 64%; through a comprehensive analysis of the thermal efficiency of waste heat power generation and direct heat supply processes, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.
