Abstract

1,090,485. Vertical vapour generators. BABCOCK & WILCOX CO. Jan. 18, 1966 [Jan. 18, 1965], No. 2250/66. Heading F4A. Coolant from a pressurized water reactor, flows through a bank of parallel tubes 26 extending between inlet and outlet chambers 20, 24 respectively of a heat exchanger shell 12. Liquid at a mass flow rate of between 100,000 and 300,000 pounds, per hour, per square foot of generator cross-section, to maintain " nucleate ", as opposed to " film " boiling around the surface of the tube bank 26, is sprayed through openings 56 from feed header 54 into the annular downcomer passageway 31 formed between the shell 12 and a lower cylindrical shroud 28. The liquid then rises with a flow velocity between 12 and 70 feet/sec. around the tube bank 26 and absorbing heat therefrom is vaporized by the time it reaches the level of openings 32 in the upper end of the lower shroud 28. Part of the vapour is drawn through the openings 32 and mixes with the liquid from inlet sprays 56, thereby condensing, and so heating the liquid to its saturation temperature. The remainder of the vapour passes in a tortuous path around the disc and annular shaped baffles (42) and 44A, 44B, respectively to be superheated in chamber 48 before passing out through vapour outlets 50. The heat exchanger shell 12 is supported on a pad 70 by a skirt 68.
