Abstract
A method whereby the potential of coal having a sodium content high enough to foul coal burning equipment is significantly reduced. The method comprises selectively crushing the coal and separating it according to particle size into low and high potential fouling fractions and recovering a sodium containing coal having a low potential for fouling coal-burning equipment.
