Abstract

A heating chamber is rotatable about its longitudinal axis and contains a number of heating tubes orientated parallel to each other. Solid material which is lifted up during the rotation can become detached from the heating tubes and upon impact can lead to damage to heating tubes which are situated below. In order to prevent such an occurrence, baffle shells are provided on the heating tubes. The baffle shells are formed of a resistant material and offer protection against surface damage. The heating tubes are preferably disposed in radially orientated rows.
