    Coal washing is a pre-combustion cleaning technology that removes some impurities contained in coal before it is burned. Modern coal-washing preparation plants rely on the principle that coal is less dense than its associated ash-forming minerals and impurities.

    Aug 19, 2005 Analyzed washed coal and washing plant reject samples indicate that the mercury is associated with the coal fraction when compared to in-place analyzed coal Table 1, Table 2. The mineral matter is distributed throughout the coal as small partings and as plant-cell fillings, and therefore was not completely washed from the coal.Aug 19, 2005 Analyzed washed coal and washing plant reject samples indicate that the mercury is associated with the coal fraction when compared to in-place analyzed coal Table 1, Table 2. The mineral matter is distributed throughout the coal as small partings and as plant-cell fillings, and therefore was not completely washed from the coal.moved. Because coal suppliers to these power plants employ some voluntary coal cleaning, the anticipated emissions reduction from current levels should be near 20. Costs then were estimated for FGD systems designed to remove the same amount of SO2 as was achieved by PCC through the use of partial scrubbing with bypass of the remaining flue gas.
