Abstract

1447155 Tubular heat exchangers; boilers WESTINGHOUSE ELECTRIC CORP 12 Aug 1974 [21 Aug 1973] 35471/74 Headings F4S and F4A In a shell and tube heat exchanger, e.g. a steam generator, comprising two groups 9, 13 of field tubes projecting into the shell 3 from opposite ends thereof, the tubes of one group are interdigitated with the tubes in the other group and the spaces in the shell between the tubes contain a solid heat transfer medium whereby heat is exchanged between fluid, e.g. liquid sodium, flowing through said first group tubes 9 and fluid, e.g. water, flowing through said second group tubes 13. Each field tube comprises outer and inner tubes 35 and 37 extending from respective tube plates 11 and 12, the end of the outer tube 35 being closed by a simple end cap (44, Fig. 12) or by a closure having guide means (46, Fig. 13) for receiving the end of the inner tube 37 which is formed with openings (47) providing fluid communication between the inner and outer tubes. The inner tube 37 may have a double wall, the space between the inner and outer wall portions being filled with an insulating material (73, Fig. 15). The outer tubes of the two tube groups may be of different size (see Fig. 4). As shown the solid heat transfer material comprises elongate metallic strips 49<SP>1</SP> of cruciform shaped cross-section which have interlocking stepped abutting edges. The strips 49<SP>1</SP> having openings 50 therein for the passage of an inert gas which is supplied to the shell through an inlet 33 and withdrawn through an outlet 34; the pressure of the inert gas is maintained higher than the pressure of the liquid sodium in the tubes 9. When adjacent tubes abut one another (see Fig. 2), non-interlocking strips (49) are used. In a modified embodiment (see Figs. 5 and 6, not shown) the heat transfer material comprises a plurality of stacked plates (53) having holes (55) therethrough for receiving the tubes and smaller holes (57) for the passage of inert gas; groups of stacked plates may be separated from one another by insulating plates or pads (59). In a further embodiment (see Fig. 7, not shown) the heat transfer material (61) is particulate; the inert gas either flows directly through the particulate material or through tubes (63) embedded therein.
