Different Types of Kiln Construction

The damper is at the top of the kiln and controls the exhaust (and, by association, the kiln's atmosphere). The stack area is where the pots are set and it's between the firebox and damper. Although an updraft kiln tends to be less fuel efficient than a downdraft kiln, most commercially built fuel-burning kilns are updrafts.
