Description
This dataset represents the average situation of natural gas power generation in China. Its data are obtained by weighted aggregation of the production datasets of Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia, Liaoning, Jilin, Heilongjiang, Shandong, Henan, Shaanxi, Ningxia, Xinjiang, Anhui, Guizhou, Shanghai and other provinces (regions, municipalities). For the production datasets of specific regions, the power generation efficiency of the power plants is determined based on official statistical data. Information on the emission inventory data:
· The emissions of CO2, particulate matter and waste gas are mainly estimated based on the material balance and pollutant generation coefficients related to the gas quality parameters, and NOx emissions are assumed to comply with the standard limit values for pollutant emissions from thermal power plants.
· The emissions of CH4 and N2O are estimated using the default emission factor values specified in IPCC 2006 for natural gas combustion in the energy sector.
· Particulate matter emissions with a particle size smaller than 2.5 μm are mainly considered.
· All emissions take into account the average removal efficiency of flue gas pollution control technologies in Chinese thermal power plants.
