<p>The invention relates to a regenerative, rotating heat exchanger of the kind having a cylindrical part containing regenerative mass and sector plates (6) separating media flows, which sector plates have outer ends provided with sliding shoes (25) displaceable perpendicular to the sector plates and lockable, and maintaining a predetermined clearance between the ends of the sector plates (6) and an edge flange (12) or similar member of the cylindrical part against which edge flange (12) the sliding shoes (25) are arranged to slide. The sliding shoes (25) have wearing surfaces made of carbon or graphite and can be screwed by a screwing mechanism (51, 52) forward some mm at a time in correspondence to the abrasion. According to the invention an essential reduction of the wearing velocity is obtained due to the fact that each sliding shoe is provided with a guiding means (23, 29) which at the forward displacement of the sliding shoe (25) prevents its turning thereby maintaining a constant abrasion pattern.</p> |
