The characteristics of municipal solid waste (MSW) processed by the Municipal Solid Waste Incinerator (MSWI) in the urban area of Chenghai City, Guangdong Province, are as follows: food waste 30.57%, paper 13.48%, rubber 37.71%, textile (fiber) 4.7%, wood and bamboo 3.12%, ash and soil 5.54%, bricks, tiles and ceramics 2.51%, glass 2.18%, metal 0.18%, other 0%. Moisture is 48.94%, higher calorific value of 9868.38 kJ/kg, lower calorific value of 7935. 48 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. Fly ash and slag, at a rate of 05kg, undergo precious metal recovery before being landfilled. Fly ash is solidified with cement at a ratio of 1:1. The heat efficiency of waste heat power generation takes the average value, which is 22%. In the process of waste heat supply, there is no conversion between different forms of heat and energy, so the heat efficiency is high, taking the average value as 64%. Through a comprehensive consideration of the heat 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.
