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.
