Description du jeu de données

The characteristics of urban solid waste processed by the municipal solid waste incinerator (MSWI) in the rural area of Mianyang City, Sichuan Province, are as follows: kitchen waste 65.17%, paper 10.28%, rubber 7.4%, textile (fiber) 10.13%, wood and bamboo 2.6%, ash soil 0%, brick and tile ceramics 0.06%, glass 0.86%, metal 0.44%, and others 1.62%. It has a moisture content of 58.2%, higher calorific value of 5936.53 kJ/kg, and lower calorific value of 3966. 86 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific waste materials such as plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please itemize the corresponding waste separately. For each kg of this type of waste, 0.205 kg of slag and 0. The fly ash and slag, at a ratio of 05kg, are subjected to precious metal recovery before being landfilled. For solidification treatment, the fly ash is mixed 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, resulting in a higher heat efficiency, averaged at 64%. Through a comprehensive analysis of the thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.

Description technologique

In China, 90% of waste-to-energy incineration plants use mechanical grate furnaces. The waste heat boilers are divided into vertical, horizontal, and II types, with horizontal being the main type. On average, the following facilities are equipped: in-furnace denitrification system, semi-dry flue gas deacidification tower, dry powder injection, activated carbon injection adsorption system, fabric filter, with the in-furnace denitrification system mainly using selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR).

Contexte géographique

The mean annual temperature (MAT) in this region is 8.70149420558138 degrees Celsius, and the mean annual precipitation (MAP) is 167.134202447367 millimeters per year. In the wastewater treatment plant, 0% of the influent is lost to pond evaporation, and 0.144% of the water is removed from the site through sludge processing. [en]
