1,096,410. Heat exchanger tube supports. BABCOCK & WILCOX CO. Oct. 1, 1965 [Oct. 1, 1964], No. 41689/65. Heading F4S. Each row of tubes 14, 14A, 14B of a helical bundle of heat exchanger tubes is supported and held spaced apart in both the vertical and horizontal position by a support comprising a first member 20 notched along one edge to receive the tubes of the row. Teeth 22 between the notches project beyond the opposite side of the tubes, which are clamped by a pair of notched bars 24 welded to the opposite edges of the teeth 22 to project therebeyond and form a guide channel for a second member 20A supporting the adjacent row of tubes 14A Each row of tubes is supported in this way, the support members 20, 20A, 20B being supported by a support 16 in the upper region of the heat exchanger pressure vessel, while the support members on the outermost edges of the tube bundle are positioned by guides (29) on the inner surface of the pressure vessel wall, Fig. 4 (not shown).
