Rotary regenerative heat exchanger

A regenerative heat exchanger includes first and second parts. The first part is essentially cylindrical, includes a regenerative mass, and is rotatable in relation to the second part around a common center axis. The second part includes axially directed inlets and outlets for heat emitting and heat absorbing media. The inlets and outlets of the second part are mutually separated by sector shaped plates for sealing purposes positioned near to end surfaces of the first part. The sector shaped plates are pivotally connected to axially fixed center plates attached to the second part at ends of the first part, and each of the sector shaped plates includes at a radially outer end thereof a device which has at least one support member including a circular cylindrical sliding shoe for setting a clearance between respective ends of the sector shaped plates and an edge flange provided at each end of the first part. The support member is journalled axially displaceable in a socket at the respective ends of the sector shaped plates perpendicular to the sector shaped plates, and is adjustable by means of a screw mechanism attached to the respective ends of the sector plates. The support member and the socket are provided with a guiding mechanism for preventing turning of the sliding shoe in the socket.
