Abstract

997,846. Gas heaters; heat exchange elements. K. W. STOOKEY. May 17, 1963 [Aug. 9, 1962], No. 19803/63. Heading F4S. In a heat recuperator in which a furnace gas flows through tubes 36 over which passes the gas to be heated, the tubes extend between two walls formed of refractory blocks 20, each capable of individual movement to relieve thermal stress, the walls constituting the boundaries between the heating gas header chambers 14, 50, and the intermediate chamber 26 in which a cool gas is heated as it flows through narrow passages 60 formed around each tube by sleeve elements 54 which are radially spaced from the tubes 36. The heat exchanging fluids may move in countercurrent flow or in co-current flow. As shown, hot flue gases pass downwardly, through the tubes 36 to the chamber 50 and to a stack 52. Air or fuel gas enters a chamber 62 through a duct 22 and then flows upwardly through the spaces 60 between the tubes 36 and their surrounding sleeves to finally enter the chamber 26 through which the tubes extend. The heated air or gas is discharged through a port 24 to the furnace combustion units. A stack of heat-absorbing and radiating elements extends within each tube (see also Fig. 2, not shown), and is supported by a flange 44 formed on the lower block 20. The sleeves are spaced from the tubes by axially extending ribs 58 (Fig. 2, not shown). The tube ends bear against partspherical seatings formed in the blocks 20 and in the countercurrent flow apparatus shown, the seal between the tube ends and the blocks is maintained by downward pressure due to the weight of the upper blocks 20. In a co-current flow apparatus described (Fig. 4, not shown), the sealing pressure is maintained by springs 90. Sealing between adjacent blocks is by means of a resilient ceramic packing, e.g. of fibrous material which is packed into wedge-shaped gaps 32 formed by suitably shaping the block edges. Individual movement of a block compresses the packing at its narrower edge and maintains the seal.
