| Abstract |
|
In this study, the distributions of hazardous heavy metals (HHMs) in TSP, PM10, PM2.5 were investigated. In the coal used in the tested plant, that Zn and Cu were most common HHMs, and Cd was rarest. In TSPs from the SCR inlet, FGD inlet and stack, the content of Zn in the coal was the highest, but the distributions of other HHMs were different. At the SCR inlet, the distributions of HHMs in PM10 and TSP differed, and concentration of HHMs in PM10 and TSP was increased. At the FGD inlet and stack the HHM distributions in PM10 and TSP were the same. At the SCR inlet, the HHM distribution in PM2.5 differed from those in TSP and PM10. At the SCR inlet, the HHM concentration was higher in PM2.5 than in TSP and PM10. At the FGD inlet and stack the distribution of HHMs in PM2.5 was very different from those in TSP and PM10 at FGD. |
