Accounting of SO2 Emissions from Combustion in Industrial Boilers

Abstract

Combustion in industrial boilers has become a major source of acid rain pollution due to the huge emissions of SO2. This study builds the accounting framework of SO2 emissions from combustion in industrial boilers and set up a high resolution SO2 emissions inventory of Beijing-Tianjin-Hebei region. We integrate the emission allocation methods in chemical species and space to calculate the total amount of SO2 emissions. Based on the GAINS model, this study further allocated the total SO2 emissions to each district of Beijing-Tianjin-Hebei region according to the quota of coal consumption of industrial boilers. Thus, a high resolution SO2 emission inventory was set up to provide solid foundation for effective air quality management and mitigation strategies of Beijing-Tianjin-Hebei region.
