The effect of moisture on coal has been studied for many years by Stock, and the resultant density changes are measured by the Gravimetric Feeder. The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand.
The first Stock gravimetric feeder operated from 1957 to 1992, to be replaced by current gravimetric microprocessor-controlled design. This feeder was donated to Stock Equipment, refitted, and refurbished for public display in the engineering plant. Drawing from patent documents for Gravimetric Coal Feeder.

Gravimetric Coal Feeder manufactured by Demech is essentially a belt conveyor which measures the amount of coal, in terms of weight, being conveyed / fed to the pulveriser.
Therefore, as coal moisture increases, at constant weight the actual amount of coal Btus decreases because the gravimetric feeder is set to keep the total of "coal plus water weight" at 100 percent.
