Description

The dataset represents the average \"municipal solid waste, incineration with cogeneration\" treatment situation in the northwestern region of China, which includes: Shaanxi, Gansu, Qinghai, Ningxia, and Xinjiang.\\nWaste processing activities are based on an average urban/public waste mixture and are not suitable for single specific waste types such as plastics, paper, cardboard, etc. If your waste consists of a specific waste mixture, please inventory the corresponding waste separately. For each kg of this waste, 0.205kg of slag and 0. 05 kg of fly ash and furnace slag, after the recovery of precious metals, were landfilled. The fly ash was solidified with cement in a 1:1 ratio. By integrating the heat efficiency of the waste heat power generation process and the direct heat supply process, 15% of the heat generated during the waste incineration process was used for power generation, and 56% was used for direct heating. This dataset was calculated based on the urban and rural construction statistics yearbook, focusing on urban appearance and environmental sanitation conditions 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.

Geography comment

The mean annual temperature (MAT) in this region is 18.5119675855206 degrees Celsius, and the mean annual precipitation (MAP) is 1636.93721521145 millimeters per year. In the wastewater treatment plant, 0% of the influent is lost due to pond evaporation, and 0.144% of the 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).
