Abstract (en)

[origin: WO9633381A1] A rotary regenerative heat exchanger has a rotor containing a regenerative mass and rotating in a stationary casing. Movable sector plates (6, 8) are arranged at each end of the rotor at a short distance (S) therefrom in order to sealingly separate media ducts. Each sector plate (6, 8) is supported by a pair of support means (10) including sliding shoes (17), which slide on an end surface (11) on a flange (9) at the outer periphery of each rotor end. Portions of the rotor flange (9) might slant, causing misalignment of the sliding shoes (17). According to the invention this problem is overcome in that each sliding shoe (17) is movably mounted in the sector plate (6) allowing the sliding shoe (17) to tilt around a tilting point (0) so that the sliding shoe (17) adapts to the local deviations of the end surface (11) on the rotor flange (9) from the plane perpendicular to the rotor axis.
