摘要

Beijing, the capital of China, revised the emission standard for air pollutants for boilers in 2015. To promote fulfillment of the new standard, the “coal to gas project” and the “reward replaces subsidy policy for low-NO_(x) retrofits of boilers” were implemented recently, and the emission of pollutants from boilers has significantly changed as a result. In this study, a comprehensive unit-based emission inventory of multiple air pollutants, including PM_(10), PM_(2.5), CO, SO_(2), NO_(x), VOCs and NH_(3), from both coal-fired and gas-fired industrial boilers in Beijing in 2015 was established with data on annual activity and category-specific emission factors, and scenario analysis and the CMAQ model were used to forecast the environmental impacts of the revised standard during the heating season in Beijing. Our results showed that in 2015, the emissions of CO, NO_(x), PM_(2.5), PM_(10), SO_(2), NH_(3) and VOCs from the industrial boilers in Beijing were about 51,745 t, 27,943 t, 10,143 t, 14,624 t, 20,227 t, 197.55 t and 1304 t, respectively. Coal-fired boilers were the major source of CO, SO_(2), PM_(2.5) and PM_(10), while gas-fired boilers were the major source of VOCs and NH_(3). Furthermore, in IPC-1 and IPC-2 scenarios, which represent the different levels of implementation of the “low-NO_(x) retrofits policy” as well as the replacement of all coal-fired boilers with gas-fired boilers, the ambient concentration of PM_(2.5) and SO_(2) was reduced by about 7.1% and 9.5%, respectively, and the concentration of NO_(2) was reduced by about 4.4% in IPC-1 and 3.7% in IPC-2 during the heating season in Beijing.
