kiln

A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks. Various industries use rotary kilns for pyroprocessing and to transform many other materials.

For a process to be efficient, we must get most of the energy into the material and later exhaust the rest. In addition to driving the process, heat transfer is also important for the control of the rotary kiln process. This chapter presents the classical heat transfer modes and their equations as they relate to the rotary kiln environment.

While rotary kilns have the ability to remove moisture from a material, this tends to be a less efficient process. In a rotary kiln, material is typically not showered like in a rotary dryer, but rather, slides along the interior of the rotary kiln. This results in lower heat transfer between the material and the gas.
