The characteristics of urban solid waste processed by the Municipal Solid Waste Incinerator (MSWI) in Shaanxi are as follows: food waste 38.6%, paper 9.3%, rubber 10.1%, textiles (fibers) 1.4%, wood and bamboo 7.4%, ash and soil 0%, bricks, tiles and ceramics 23.3%, glass 6.5%, metals 3.4%, and others 0%. It has a moisture content of 45.85%, higher calorific value of 5445.04 kJ/kg, and lower calorific value of 3802. 42 kJ/kg. Waste treatment 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 generates 0.205 kg of slag and 0. The fly ash and slag, at a ratio of 05kg, are recovered for precious metals before being landfilled, with fly ash solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is taken as 22%; in the process of waste heat supply, there is no conversion between different forms of heat and energy, so the heat efficiency is higher, taken as an average value of 64%; through the comprehensive heat efficiency of waste heat power generation and direct heat supply, 15% of the heat generated during waste incineration is used for power generation, and 56% is used for direct heating.
