Rotatable heating chamber equipped with internal piping, for waste

摘要

The heating chamber which is rotatable about its longitudinal axis (10), for solid materials, in particular a low-temperature carbonisation drum (8) for waste (A), possesses a number of heating tubes (12a) which are accommodated in its interior (13) and aligned approximately parallel to one another. To ensure that the height of fall of the solid material collecting on the heating tubes (12a) during the rotation of the heating chamber is as small as possible, the invention provides that the heating tubes (12a) - seen in cross-section - are arranged in non-radial rows, each row starting roughly at the inner wall (33) and extending from there into the interior (13). <IMAGE>
