Thermal desorption of mercury from lignite in a high …
2.2 Investigation of mercury release from lignite in power plant mills. At two power plants, lignite samples (Lignite A and Lignite B) were taken simultaneously at the feeder before entering the coal mill and from the dust line after the coal mill. Afterwards, the raw lignite and the ground lignite were analyzed for mercury concentration.
