Abstract
1469974 Tubular heat exchangers; steam superheaters STAL-LAVAL APPARAT AB 12 June 1974 [13 June 1973] 26010/74 Headings F4S and F4A In a shell and tube heat exchanger used for heating gas, vapour or liquid, e.g. superheating steam, and comprising at least two superimposed and series connected tube nests 11 and 12 or horizontally disposed U-tubes through which heating medium in the form of steam is passed, the tube nests 11 and 12 are connected to respective condensate draining tubes 19 leading to one or more steam barriers 18. In use steam from a steam inlet chamber 17 is fed to the upper limbs of the lower tube nest 12 and is thereafter transferred from the lower limbs thereof to the upper limbs of the upper tube nest 11 through pipes 14, said steam leaving the lower limbs of said upper tube nest 11 through an outlet 16. The lower tube nest 12 has more tubes than the upper one 11. The fluid to be heated passes upwardly over the U-tubes in cross-flow relationship, and the tubes are supported in the shell by apertured support plates 13.
