Abstract
1292236 Vapour generator BABCOCK & WILCOX CO 19 April 1971 [2 March 1970] 22883/71 Heading F4A A vapour generator includes an upright pressure vessel 11 containing a bank of heat exchanger tubes 18 for primary fluid, a shroud 51 defining a flow path 52 for secondary fluid, there being an annular space 55 between the vessel and the shroud, means supplying secondary fluid to the space 55, from the lower end of which it flows into the path 52, from which some fluid may be mixed with fluid entering the annular space, and auxiliary means arranged to discharge secondary fluid into the shroud. The main supply of secondary fluid, from nozzles 30 connected to header 32, which comprises two arcuate tubes (Fig. 3, not shown) is discharged into the space 55 at or near the top of cylinder 19, which constitutes the lower part of the shroud 51, and passes into the interior of the cylinder through openings 22, where it is vaporized by heat from the primary fluid, which may be coolant from a nuclear reactor, passing down the tubes 18. Some vapour passes into upper cylinder 24, where it is superheated, into the upper part 26 of annular space 55, and is withdrawn through outlets 38. Some vapour however passes through opening 28 between the cylinders 19 and 24 and preheats the fluid entering from the nozzles 30, so that thermal shock to the metal is minimized. In the event of a plant shutdown, with the cessation of supply from nozzles 30, auxiliary secondary fluid is supplied directly into cylinder 24 from nozzles 33 until the primary fluid in the tubes 18 has cooled. In the event of a hot restart, vapour from the auxiliary secondary fluid is mixed with the cold fluid entering from nozzles 30 in order to preheat it.
