Abstract
A heating chamber for solid material, preferably a low-temperature carbonization drum for waste, is rotatable about its longitudinal axis and is equipped with a number of heating tubes that are disposed in an interior space and are aligned approximately parallel to one another. In order to ensure that only fine material can collect between the heating tubes and the inner wall surface of the heating chamber, the heating tubes, as viewed in cross-section, are disposed in a virtually closed row along the wall. Dummy tubes which are preferably easy to remove and preferably have the same diameter as the heating tubes, are located in this row, which may be circular.

A heating chamber for solid waste material, comprising:
- a wall defining an interior space and a longitudinal axis about which the heating chamber is rotatable;
- and
- a number of heating tubes being disposed along said wall in said interior space as seen in cross section of said interior space, said heating tubes being aligned approximately parallel to one another and having a given diameter, said heating tubes along said wall being spaced apart from each other by a spacing being less than half of said given diameter, said spacing being in a range of between 20 and 40 mm, and said heating tubes along said wall being spaced apart from said wall by a spacing being less than half of said given diameter for protecting said wall from being damaged by lumps of solid waste material when the heating chamber is rotated.
