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. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
