Abstract

A predictive model for PM_2.5 emissions from Coal-fired boilers was developed based on the technology distribution and the emissions inventory methodologies applied domestically and abroad. Three scenarios were designed to analyze the emission potentials and distributions of PM_2.5 from coal-fired boilers in Beijing-Tianjin-Hebei area in 2020. The results showed that PM_2.5 emissions from coal-fired boilers were 1.25×10⁴t, 0.58×10⁴t and 0.18×10⁴t under different scenarios in 2020, respectively. Compared with the base year, PM_2.5 emission reductions of coal-fired boilers were 6.6×10⁴t, 7.2×10⁴t and 7.6×10⁴t, respectively, with the reduction rates of 84.0%, 92.6% and 97.7%. Emission reduction potentials in different cities are dependent on coal consumption by coal-fired boilers, capacity of boilers, ash content of the coal and dust control measures. The reduction potentials from coal-fired boilers of Tianjin were largest in Beijing- Tianjin-Hebei cities. Shijiazhuang was the top city in terms of reduction potentials in Hebei province. In the enhanced control scenario, the emissions reduction potentials could exceed 0.5×10⁴t in Tangshan, Beijing, Baoding and Qinhuangdao.
