Drying factors are established in the same manner; coals are allowed to dry in a heated laboratory under certain constant conditions of evaporation. If it takes 3 hr to dry a certain size from its final point of drainage, say 5 pct moisture, to the required point of drying, say 2 pct, the drying factor of this coal will be 3.
