Rotary regenerative heat exchanger

A regenerative heat exchanger comprising first and second parts, wherein:

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