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。

The Effect of Mercury Content in Coal on the Level of Mercury Emissions from Coal fired Power Plant Flue Gas
YU Mei xiang,YANG Li,KOU Xiao fang
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.
