Abstract

1275298 Vapour generators COMBUSTION ENG Inc 14 Aug 1969 [16 Aug 1968] 40758/69 Heading F4A A vapour generator, Fig. 1, utilizing liquid metal or molten salts comprises a heat exchange chamber 22 containing pressure tubes 46 which connect a downtake plenum 33 with a vapour collection chamber 18, each pressure tube 46 concentrically containing a tube arrangement, Fig. 2, which comprises tubes 56, 60 the latter tubes being connected to an inlet plenum 28 for vaporizable liquid. The liquid (water as described) flows up tubes 60 and down the annular passage between the tubes 56, 60 to an evaporator outlet plenum 30 as a steam water mixture. The latter results from the liquid metal or molten salts, from a nuclear reactor, which enter through an inlet 24 and are directed by baffles 72, 54 around the tubes 46 to an outlet 26. The mixture is then delivered to separators 74 from which the separated water returns to the inlet plenum 28 via the downtake plenum 33 and pump 42. Separated steam is passed through a drying screen 76 to flow up the annular space between tubes 56, 46 into the collection chamber 18 and then through an outlet 20 as superheated steam which drives a turbo-generator set. The superheating is achieved by tube extensions 64 having spiral fin spacers 66 to direct the steam against the walls of respective tubes 46. Fin spacers 68, 70 act also as guides for steam flow. When certain high temperature liquid metals are used a blanket of inert gas such as argon is provided between a tube sheet 48 and baffle 80 to reduce thermal stress and shock. An additional baffle 82 causes flow reverse of the exiting heating medium to separate any entrained inert gas.
