Abstract
1358336 Heat exchangers GULF OIL CORP 10 Oct 1972 [28 Oct 1971] 46649/72 Heading F4A A heat exchange arrangement comprises a plurality of tubes for fluid to be heated arranged as an assembly of coaxial helical coils in a flow of heating fluid; the tubes being linked in pairs at one end of the assembly and means being provided at the other to introduce fluid under pressure into one tube of each pair and to receive heated fluid from the other. In the arrangement shown the helically arranged heat exchange tubes 13 are employed in the reheater of a steam generator associated with a gascooled nuclear reactor. The steam generator 39 receives primary gas, helium or carbon dioxide, through duct 43 from core area 33, and the gas generates steam in tubes 63 before being returned to the core through duct 45. Steam for reheat is passed into inlet tubes 105, which constitute half of the tubes 13, and at the end of the tubes remote from the inlet passes through linking sections 21 into the remainder of the tubes to travel back to the outlet tubes 107. As shown there are even numbers of coaxial coils and pairs of coils are linked by the sections 21. In an alternative embodiment (Figs. 3, 4, not shown) each coil has an even number of tubes and pairs of tubes in the same coil are linked. In the steam generation section, feedwater enters at 57 and passes through tubes 61 arranged between double walls 17 to steam bundle 63 which constitutes a combined evaporatoreconomizer and superheater arrangement; steam then passing via tubes 65 down cylinder 67 to outlet 71. Heating gas moves from inlet 43 down over the tubes 13, which are arranged between walls 17 and 19 then up the duct formed between wall 19 and the cylinder 67. At the top of the assembly the gas is diverted by wall 89 down over the tubes 63, then is drawn around the lower edges of shell 81 and up over the outside of the shell by gas circulator 41; moving into duct 99 which communicates in an upper region (not shown) with the outlet duct 45.
