Before delving into specifics, it's important to recognize that there are two basic types of kilns: continuous (tunnel) kilns and periodic (intermittent) kilns. Continuous kilns are always firing, so they never cool. The ware to be fired is loaded into cars and slowly goes through the kiln on a track or rail.
The kiln circuit can be oval, rectangular or circular. Because of the counter flow arrangement, the incoming air encounters hot bricks exiting from the combustion
Kilns have taken many different forms over their long existence and continue to. need to by supported by grooves cut into the brick of the side walls of the kiln.
In this type of kilns, usually bricks are not in the direct contact with fire. Down-
The heat from the kiln's fire can harden the bricks to finish them. A kiln for firing bricks may be very large and require many bricks. This kind of kiln can be seen in
