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.

Introduction. Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coalfired thermal power plants, the raw coal is first pulverized to the shape of flour before it is forcefed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated ...
