Abstract

1330615 Thermal regenerators H BRANDT A KRITZLER [trading as APPARATEBAU ROTHEMUEHLE BRANDT & KRITZLER] 5 April 1972 [6 April 1971] 15775/72 Heading F4K In a rotary duct-stationary matrix type regenerative air preheater, the cylindrical heat exchange matrix 1 includes a rotatable portion adjacent its lower cold end, the rotatable portion comprising a carrier 7 containing a plurality of sector shaped heat exchange units 31, 32, 33. The stationary part of the matrix is subdivided by fixed partitions 2, 5 and 6 into segment shaped compartments each containing an assembly of heat exchange elements 36, 37, 38. Rotation of the carrier 7 makes each radial set of units 31, 32, 33 selectively replaceable through a normally closed aperture 40 in the outer wall 4 of the matrix. Heating gas enters and leaves the regenerative matrix by way of fixed ducts 41, 43, whereas air to be heated flows in the opposite direction entering and leaving by way of rotatable hoods 44, 45, the hoods being driven through gearing 47, 48. In normal use the partition walls 2a of the carrier 7 are kept in axial alignment with the radial partition walls 2 of the stationary part by means of releasable locating elements 50 which lock the carrier 7 against rotation in selected positions. Replaceable elastic sealing elements 25 on the partition walls 2a abut against U-shaped wear shoes 26 attached to the lower edges of the stationary partition walls 2. Sector shaped isolating plates (52, 53, Figs. 7- 9) may be inserted above and below the carrier 7 in order that undisturbed operation of the air preheater be maintained during installation or removal of the cold end heat exchange assemblies 31, 32, 33 through the aperture 40. The carrier 7 can be detachably coupled for rotation to the cold end air hood 44 through links 55.
