Description

The dataset represents the average \"municipal solid waste, incineration for power\" treatment situation in the North China region, which includes: Beijing, Tianjin, Hebei, Shanxi, and Inner Mongolia. The waste treatment activity is based on an average urban/public waste mixture and is not suitable for a single specific waste such as plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please separately account for the corresponding waste. For every kg of this waste, 0.205kg of slag and 0. The fly ash and furnace slag, after recovery of precious metals, are landfilled. The fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is 22%. This dataset is calculated based on the Urban and Rural Development Statistics Yearbook, focusing on urban appearance and environmental hygiene in the region.

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.

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).
