Abstract
689,522. Rotary regenerative heat-exchangers. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. Feb. 14, 1951 [Feb. 18, 1950], No. 3580/51 Class 64 (i). Relates to rotary regenerative heat-exchangers having a cylindrical rotor including a shell 10, carrying heat transfer material, a housing 20 surrounding the rotor and provided opposite the ends of the latter with sector plates 21 formed with apertures 22 for the flow of heating gases and air to and through the rotor. According to the invention, a ring comprising a plurality of arcuate sealing members 40 is mounted at each end of the rotor shell and is maintained in sealing relation with a ring of sealing shoes 51 mounted on each of the sector plates 21 outwardly of the rotor. Preferably each of the sealing members 40 on the rotor shell is independently movable axially of the rotor and each of the sealing shoes 51 on the sector plates has independent movement in a radial direction, the esaling members 40 each having a shoulder which engages with an axial face 52 formed on a shoulder 50 of the sealing shoes 51. The sealing memters 40 on the rotor whilst movable independency axially are maintained in fixed axial relation to the sector plates 21 by guide plates 60 bolted to the sector plates and engaging behind lateral flanges 47 on the sealing members 40. The shoulder 50 on each sealing shoe 51 engages in a groove 48 formed on the sealing members 40 so that a sealing relationship is maintained independently of radial expansion or contraction of the rotor. Alternatively the sealing shoes 51 may be pressed against the sealing members 40 by a spring and lever arrangement, Fig. 6 (not shown). A labyrinth circumferential seal is provided adjacent the rotor post 12 (Fig. 3). The rotor is preferably divided by radial partitions 11 (Fig. 5) into cells and radial sealing members 30 of cast aluminium are provided on each partition. The sealing members 30 are mounted on each end on slotted lugs 80, 81 formed respectively on the labyrinth sealing members 62 adjacent the rotor post and on the sealing members 40, the lower edge of the members 30 being spaced from the radial partitions 11 and being formed with a groove 85 in which rides a spring plate 84 carried by clamp plates 86 from the partition 11.
