Abstract

591,602. Tubular heat exchangers. BABCOCK & WILCOX, Ltd., and EVANS, R. H. March 29, 1945, No. 7973. [Classes 64 (i) and 64 (iii)] A heat exchanger, e.g., an economiser, comprises a bank of tubes constituted by tubular heat exchange elements each formed by a tube bending process and each including tube lengths connected in series by return bends so arranged that the tube lengths are in staggered relationship, the elements being assembled with tube lengths of adjacent elements alternating in a tube row in which those tube lengths are aligned or substantially aligned, so that the pitches between the tube lengths in the row are less than the pitches between the tube lengths extending from the same return bends. In the form shown, a pair of tubular elements each includes tube lengths disposed in two parallel rows with tube lengths 5..10 of one element alternating in each row with tube lengths 11..16 of the other element. The return bends 17, 18, 19 at one end of one element are inclined in one direction, and the bends 20, 21 at the other end in the opposite direction, relatively to the rows of tube lengths and connect adjacent tube lengths in the different rows. The return bends 22..26 of the other element are oppositely inclined relatively to the neighbouring return bends of the first element, and the return bends at opposite ends of one of the elements are respectively within and without the neighbouring return bends of the other element, so that each element may be removed longitudinally without disturbing the other element. Plate screens, apertured for the passage of the tube lengths and divided into sections along the centre lines of the tube rows, are arranged' near the ends of the tube rows to position the tube lengths and shield the return bends. In a modification, the return bends at each end of an element are parallel to one another, and the tube lengths of each element are interspaced by those of elements on opposite sides.
