Data Resulting From the Study for Sulfate Explosive Growth in Wet Plumes Emitted From Typical Coal-fired Stationary Sources.xlsx

We show that sulfuric acid droplets are readily produced in wet plumes emitted from typical coal-fired stationary sources. The freshly formed sulfate originates from the condensation and absorption of SO₂ and SO₃ emitted from stacks when the discharged flue gas cools in ambient air. We discover that the fast-formed sulfate aerosols in the wet plumes from industrial stacks account for approximately 31.4% of the directly emitted sulfate aerosols in China. This data advance our understanding of industrial particulate emissions and their contribution to atmospheric sulfate.

本研究证实，典型燃煤固定污染源（coal-fired stationary sources）排放的湿烟气羽流（wet plumes）中易于生成硫酸液滴（sulfuric acid droplets）。新生成的硫酸盐源自烟囱排放的SO₂与SO₃在排放烟气经环境空气冷却时所发生的冷凝与吸收过程。本研究发现，工业烟囱湿羽流中快速生成的硫酸盐气溶胶（sulfate aerosols）约占我国直接排放硫酸盐气溶胶总量的31.4%。上述数据有助于深化学界对工业颗粒物排放及其对大气硫酸盐贡献的认知。
