Why Pulverized Coal is Used in a Power Plant
Because of the large size of coal, some of the carbon particles do not come in contact with the air. These unburned carbon particles go out with ash. This is a loss and could be in the range of 5 % or greater in the older gratefired combustion. Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream.
