Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size. Coal is commercially available in different sizes known as "Run of Mine," "stoker," "slack," etc. depending on their size. In the olden days, coal burning was done on grates without any change in size or pulverizing. Because of the large size ...

Coal use at U.S. power plants is slumping: ... This measure, called "days of burn," is more useful than simply looking at the size of the coal piles, since there are fewer coal plants than in the past, and the ones that are still operating are running less. In fact, the amount of coal used each day in the U.S. has fallen from about 2.8 ...
