ABSTRACT:
A first cylindrical drum member having an inlet portion for receiving materials to be treated, such as preheated coal and char includes a longitudinal axis and an outlet portion through which the treated materials are discharged into the inlet end portion of a second cylindrical drum member. The second drum member is independently supported for rotation relative to the first drum member and has a longitudinal axis coplanarly aligned with the longitudinal axis of the first drum member such that the drum members are concentrically positioned in tandem relative. A sealing assembly is connected to the first and second drum members for longitudinal movement with the drum members during expansion and contraction of the drum members as they are subjected to different temperatures. The sealing assembly includes a running seal member that is secured to the periphery of the respective drum members and a static seal ring assembly that is movably positioned on the outer cylindrical surface of an annular support member that surrounds the respective drum members. A plurality of piston cylinder assemblies surround the annular support member, and each includes a piston rod arranged in abutting relation with the static seal ring assembly to maintain the seal ring assembly in sealing relation with the running seal upon longitudinal movement of the first drum member.
