摘要:

对江苏省9家燃煤电厂入炉煤中ω（汞）及烟气中ρ(汞）进行了测试，结果表明，9家燃煤电厂入炉煤中ω（汞）为54.5~297 ng/g，平均值为139 ng/g，低于我国煤中ω（汞）的平均值（220 ng/g）。燃煤电厂排放烟气中ρ（汞）为0.08～16.97 μg/m3，远低于《火电厂大气污染物排放标准》(GB 13223-2011)汞及其化合物标准限值（30 μg/m3）。通过对燃煤电厂入炉煤中ω（汞）与最终排放的烟气中ρ（汞）进行分析，两者之间有一定的相关性。

Abstract:

The mercury in coal and the mercury emissions from flue gas of coal fired power plants were analyzed in Jiangsu province. The results showed that, mercury in coal of 9 coal fired power plants were 54.5~297 ng/g, and the average was 139 ng/g. The average value was lower than the average mercury in coal of China(220 ng/g). The mercury emissions from flue gas of coal fired power plants were in the range of 0.08~16.97 μg/m3 in Jiangsu province.It was lower than the mercury and compounds standard(GB 13223 2011) limits(30 μg/m3) of china. By analyzing the mercury in coal and the mercury emissions from flue gas of coal fired power plants,it was found that there was a certain proportional relationship between the two.
