    摘要： 1,010,870. Furnace recuperators; heatexchanger tube elements. H. ESCHER. Dec. 24, 1963 [Nov. 29, 1963], No. 50904/63. Heading F4S. A furnace recuperator comprises a flue 3 in which are arranged longitudinally extending tubes 10 of elongated cross-section each with its major axis directed towards the centre of the flue, means such as the headers 9 and 13 for conveying air first to the tubes where it is heated, and then from the tubes, deflectors 17 secured either to the tubes (as shown) or to the flue wall, for causing the flue gas to circulate in opposite directions around adjacent tubes, and/or means within the tubes including partition members 21 for causing the air to flow in a helical path through the tubes. In the recuperator shown, air flows also through a jacket 6 around the flue 3. The tubes may be connected to the upper header 8 by joints permitting relative expansion (Fig. 4, not shown).
