Description

The dataset represents the average \"municipal solid waste, incineration with waste-to-energy\" management situation in the East China region, which includes: Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, and Shandong. The waste management activity is based on an average urban/public waste mixture and is not suitable for单一 specific waste types such as plastics, paper, cardboard, etc. If your waste is a specific mixture, please inventory the corresponding waste separately. Each kg of this waste generates 0.205kg of bottom ash and 0. 5 kg of fly ash and furnace slag, after precious metal recovery, are landfilled. Fly ash is solidified with cement at a ratio of 1:1. By combining the heat efficiency of comprehensive waste heat power generation and direct heat supply processes, 15% of the heat generated during waste incineration is used for power generation, and 56% is used for direct heating. This dataset calculates the situation in this region based on the Urban and Rural Development Statistics Yearbook - Urban Sanitation and Environmental Sanitation in Provincial Cities.

Activity Description

After entering the incineration plant, waste is first stacked and stored. During this process, a certain amount of leachate is produced due to the high moisture content of the waste. Subsequently, the stored waste is fed into the incinerator for incineration. Flue gas generated during the incineration process is treated by flue gas purification equipment. The generated solid waste includes bottom ash and fly ash, with bottom ash deposited at the bottom of the incinerator and fly ash being emitted along with flue gas. Heat from incineration is used for power generation or heating, achieving resource utilization. Electric power generated from recovered heat can be sold or used for internal recycling within the incineration plant.

Process Description

'Municipal solid waste' primarily originates from a wide range of activities across many different sectors. 'Municipal solid waste' consists of the following fractions: food waste, paper, rubber, textiles (fibers), bamboo and wood, ash and soil, bricks and ceramics, glass, metals, and potentially other fractions. These by-products (recyclable or waste) are produced by common transformation activities, thus it's plausible to model the waste output for similar components. In the HiQ database, the handling methods for these by-products include: deposition - sanitary landfill, municipal incineration. Additionally, these by-products are also utilized in the following processes: clinker production.

Geography comment

The annual mean air temperature (MAT) in this region is 16.4172928373904 degrees Celsius, and the mean annual precipitation (MAP) is 1277.00858543402 millimeters per year. In the wastewater treatment plant, 0% of the influent is lost due to pond evaporation, and 0.144% of water is removed from the site through sludge processing.

Technology comment

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).
