The furnace body is generally made of high-quality carbon steel, commonly used for materials with a moisture content.30%The activated carbon drying process can primarily utilize the heat source from waste heat boilers, eliminating the need for additional heat sources. Through the operation of this system, most of the moisture and low-boiling point volatiles in the activated carbon can be removed, facilitating the smooth progression of the subsequent high-temperature desorption step.

Equipment lengths range from a few meters to several tens of meters, determined by factors such as processing capacity and moisture content. In addition to activated carbon, effective drying can also be performed on slag, catalysts, and waste residues.
