The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in Hainan city are as follows: food waste 58.42%, paper 6.44%, rubber 11.93%, textile (fiber) 0.89%, wood and bamboo 1.6%, ash and soil 0%, bricks, tiles and ceramics 12.92%, glass 0.53%, metals 0.68%, and others 6.47%. It has a moisture content of 54.7%, higher heating value of 5556.5 kJ/kg, and lower heating value of 3706 kJ/kg. 33 kJ/kg. Waste processing activities are based on an average urban/public waste mixture and are not suitable for single 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 furnace slag, after the recovery of precious metals, are landfilled. Fly ash and cement are solidified at a ratio of 1:1. The average thermal efficiency of waste heat power generation is taken as 22%; during the process of waste heat supply, no different forms of heat and energy conversion are carried out, so the thermal efficiency is higher, taken as an average of 64%; through the comprehensive thermal efficiency in the process 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.
