Gayley process \Gay"ley proc"ess\ (Med.)
The process of removing moisture from the blast of an iron
blast furnace by reducing its temperature so far that it will
not remain suspended as vapor in the blast current, but will
be deposited as snow in the cooling apparatus. The resultant
uniformly dehydrated blast effects great economy in fuel
consumption, and promotes regularity of furnace operation,
and certainty of furnace control.
