ABSTRACT:
The subject of the invention is a rotary tube (1), in particular for a rotary tubular kiln for the production of activated charcoal, according to the invention the rotary tube (1) being provided on its outside with at least one reinforcing element (8) for stabilizing the rotary tube (1) in the operating state. As a result, the rotary tube (1) exposed under operating conditions to high temperatures and consequently easily deformable is stabilized in its cross section and/or in its longitudinal direction, depending on the arrangement of the reinforcing element. In particular, the rotary tube (1), for example when it is used for the production of activated charcoal, with the accompanying high operating temperatures, is equipped with efficient resistance to pronounced pressure fluctuations occurring due to the method employed and is therefore also suitable, in particular, for carrying out processes under reduced or increased pressure.
