Description
This dataset represents electricity generation from representative coal-fired power plants in Yunnan, China. The average technology is characterized by a combination of key technical parameters, including unit capacity, boiler type, and cooling method. The coal used represents regionally average coal quality characteristics and is consistent with the definition of coal for electricity generation, i.e., thermal coal with a calorific value below 6000 kcal/kg. Overall, the dataset represents average performance of coal-fired electricity generation in the region. Key emission inventory data are compiled as follows:
· Emissions of major pollutants such as CO2, SO2, NOx, and particulate matter are estimated using a material balance method related to coal quality parameters. · Emissions of CH4, N2O, CO, and NMVOC are estimated using the default emission factors for coal combustion in the energy sector as specified by IPCC 2006.
· Emissions of halogens, organic pollutants, trace heavy metal elements, and radioactive elements are sourced from the literature.
· All emissions take into account the average removal efficiency of flue gas pollution control technologies in Chinese thermal power plants.
Activity Description
The product production activity boundary covers the entire phase of power plant operation and maintenance, including coal combustion, fuel oil ignition and flame stabilization, flue gas denitrification, particulate matter removal, and flue gas desulfurization. The water treatment process for power generation process water is described in a separate dataset: cooling water treatment and softened water treatment.
Process Description
The product is grid-connected electricity measured in kWh, with a voltage level of ≥35 kV.

Technology comment
Assume that thermal power plants are all equipped with flue gas denitrification, dust removal, and desulfurization devices, as by the statistical year, a cumulative total of 1.05 billion kilowatts of coal-fired power units nationwide have been retrofitted for ultra-low emissions, accounting for 94% of the total installed capacity of coal-fired power.
