Abstract

1,014,855. Tubular heat exchangers; water tube steam boilers; superheaters. FOSTER WHEELER Ltd. Sept. 6, 1962 [Sept. 7, 1961], No. 32177/61. Headings F4A and F4S. In a tube and shell heat exchanger, for use in nuclear power plants having gas cooled reactors, one or more prefabricated heat exchange units are contained in the shell, each comprising an inlet and an outlet header joined by a bank of substantially similar tubes, and each tube having a succession of U-bends such that it is made up of at least one cluster of tube lengths running lengthwise in the shell, corresponding clusters being positioned side by side to give substantially uniform tube distribution over the shell. As shown, Figs. 6 and 7, each tube cluster is in the form of a hexagon in crosssection, with parallel sections joined by U-bends 23, the cluster being made rigid by means of pegs 32 on the upper U-bends held in a spacer plate 34. The portions of the tubes between the U-bends may have longitudinally fins or studs or pins on their outer surfaces, and each cluster may be twisted about its central longitudinal axis to a helical form to improve heat transfer. A number of hexagonal clusters are formed into a heat exchange unit, with a branched radial header 14, each unit occupying a 60-degree sector of the shell 10, Fig. 5, identical units filling the remaining sectors, which may be separated by partitions 28. Each heat exchange unit may have the inlet and outlet headers at the same or at opposite ends of the unit, while tube clusters may run the full length of the unit or, Fig. 3, each tube may have several clusters arranged end-to-end within the length of a single unit. The shell may contain one set of heat exchange units set side-by-side in sectors, or several groups of units may be fitted end-to-end into the shell, not all groups being formed of units of the same type. A vapour generator built according to the invention, Fig. 11, comprises evaporator units " A," superheater units " B," and economizer units " C " end-to-end in a single shell. The heating fluid enters at 24 and leaves at 26, the inlet 24 being in a rotatable end cover to the shell, so arranged that individual heat exchange units can be lifted out through inlet 24 for servicing.
