ABSTRACT:
A sealing medium seal for sealing the rotary drum of a drum-shaped furnace against the stationary charging device and the downstream, stationary discharge chamber, in order to prevent infiltrated air from being drawn into the process space and toxic flue gases from surging out. A double seal is provided including wearable individual sections of the sealing ring, which are equipped with a circumferential groove, with a hole, and with a sleeve for the sealing medium connection, and are arranged displaceably between two flanges as well as of a pneumatic, deformable, one-part sealing element, to which pressurized medium is admitted via a connection. The two sealing elements are guided in a chamber formed by two side flanges and a closing flange, as a result of which the sealing elements are completely sealed both in the radial direction and in the axial direction.
