Based on the data of the basic production-line information, activity level and pollutant control technologies of the flat-glass enterprises of 27provinces in 2013~2015, the calculation methods and emission inventories of SO₂ and NO_x emissions for the main atmospheric pollutants of the flat-glass industry are established with the analysis of the production, the energy consumption, the energy structure, pollutant control technology, the emission characteristics and spatial difference. Monte Carlo method is used for the uncertainty analysis of the inventories. The results show that Chinese flat glass industry uses natural gas/coal gas as the main energy, the average energy consumption per unit of product is 13.2kg tce/weight box, Shanxi and Inner Mongolia and other provinces are higher; 37% and 42% of the flat-glass production line is installed with denitrification facilities and desulfurization facilities, the main technologies are flue gas circulating fluidized bed, Dual-Alkali Method and SCR. SO₂ emissions rose first and then dropped, reached 168thousand tons in 2014, and dropped to 136thousand tons in 2015, the emission of Hubei, Zhejiang, Hebei and Guangdong were relatively large. NO_x emissions decreased continuously, from 374thousand tons in 2013 to 284thousand tons in 2015, the emission of Hebei, Hubei, Shandong and Guangdong were relatively large. The SO₂ emission intensity in the southwest region is higher than other areas, and it has a rising trend, and the SO₂ emission intensity in other areas decreased as a whole. The NO_x emission intensity in the southwest region is higher than other areas. Efforts should be made to strengthen pollutant control in areas with high energy consumption, high emission and high intensity.
