The term downdraft can also refer to a type of backdraft which occurs through chimneys which have fireplaces on the lowermost levels (such as basements) of multi-level buildings.

Shown below are just a few of the many styles of kilns. All gas kilns vary in shape but fall into two basic categories; updraft and downdraft. The difference between the two is based on heat transfer. Updraft refers to the heat transfer from the bottom inlet flue to the top exit flue. One example of this is the raku kiln. Downdraft kilns differ by having both inlet and exit flue near the floor of the kiln.
