The use of an alloy composed of 15 to 19% by weight of Cr, 5 to 32.5% by weight of Mo, 0.3 to 10% by weight of Si, up to 10% by weight of Al and up to 4.5% by weight of Ti, the remainder being Ni, as a sliding material for seals on rotary regenerative heat exchangers with a ceramic core is described. The sliding material is suitable especially for use in temperature ranges up to about 1100.degree. C.

Sliding material for seals on rotary regenerative heat exchangers with a

A seal for the gas channels of a regenerative heat-exchanger which consists of a sealing bar that abuts at a rotatable disk-shaped storage body and of a sealing diaphragm which, assisted by leaf spring elements, extends over the gap between the sealing bar and the oppositely disposed housing wall; the sealing diaphragm which is V-shaped or U-shaped in cross section, is enclosed along one of its legs and pressed against the sealing bar by a clamping strip secured at its one edge along the sealing bar; with its back side, the sealing diaphragm is disposed opposite at least one abutment arranged at the sealing bar.
