The characteristics of municipal solid waste (MSW) processed by the Hunan urban solid waste incinerator (MSWI) are as follows: kitchen waste 25.71%, paper 18.27%, rubber 22.26%, textile (fiber) 11.24%, wood and bamboo 2.33%, ash and soil 11.16%, bricks, tiles, and ceramics 1.77%, glass 2.37%, metal 2.03%, and others 2.86%. The moisture content is 45.87%, the higher calorific value of 8525.15 kJ/kg, and the lower calorific value of 6747. 63 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for individual specific waste such as plastic, 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, after the recovery of precious metals, are landfilled. The fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is 22%. In the process of waste heat supply, there is no conversion between different forms of heat and energy, so the thermal efficiency is relatively high, with an average of 64%. Through the comprehensive heat efficiency of the waste heat power generation process and the direct heat supply process, 15% of the heat generated during the waste incineration process is used for power generation and 56% is used directly for heating.
