Abstract
1,079,183. Tubular heat exchangers. WAAGNER-BIRO A.G. April 2, 1965 [April 6, 1964], No. 14165/65. Heading F4S. A heat exchanger for pressurized gaseous heat transferring fluid is substantially cylindrical in shape and comprises of banks of similarly curved length of tubing 2 extending in substantially radial planes (13) from the principal heatexchanger axis 14 to the heat-exchanger periphery, wherein lengths of tubing in different banks are interconnected by tube bends 3, 4 having radii of curvature that exceed half the or half the minimum distance between consecutive radial planes containing the tube banks. Various embodiments are described to achieve the above condition for the radii of curvature of the tube bends, in particular the tube bends 3, 4 which are immersed in the heat transferring fluids, may be angled to the heat-exchanger axis 14 (Fig. 2, not shown) so as to connect adjacent banks (13) and rows 5 or more remote banks and rows, or they may be parallel to the heat exchanger axis (Fig. 20, not shown) and connect the next-but one or more remote radial planes, or they may comprise a combination of both (Fig. 16, not shown). The tube bends, comprising of either a continuous U-bend or two right-angled bends joined by a straight portion, may all be angled in the same direction to produce a continuous coil (Fig. 2, not shown) or alternate banks angled in opposite directions (Fig. 3, not shown) to produce vertical volume (15) (Fig. 5, not shown) for the purpose of locating leakages in the tubes or dividing the heat-exchanger into separately controllable sectors. When the arcuate tubing comprises of more than one tube coil (Fig. 13, not shown) the tube bends may be concentric with different radii of curvature (Fig. 20, not shown) or with the same radii of curvature (Fig. 23, not shown), this being permitted by spreading the tube bends fan-wise (Fig. 22, not shown). The tube bends are joined to the arcuate tubing by means of straight tubes, one or two tube diameters in length, to prevent kinking in the tubes. The arcuate tubing, which is equiangularly spaced about the heat exchanger axis 14, may be formed to represent parts of involute curves, cycloid, spirals decreasing in curvature towards the heat-exchanger periphery, circular arcs interconnected by straight portions the radius of curvature of the arcs increasing towards the periphery or the length of the straight portion increasing towards the periphery. The tube bends connecting the arcuate tubing may be such that together they form a continuous kidney-shaped trace (Fig. 38, not shown). The tubes may be supported by supporting tubes 7 and brackets 8 (Fig. 1) or supported by the tube bank underneath with the aid of weblike or saddle shaped spacers (112) (Fig. 26, not shown), or suspended by means of a supporting spider (23) on hangers (16), the spider itself resting on a central column (12) supported by an inner wall (24). The flow of the medium inside the cylindrical casing is confined to the space occupied by the tube assemblies by means of insertions 10, 12 along the axis and around the periphery of the heat-exchanger (Fig. 1). Within the spaces formed by the insertions 10, 12, any tubes, such as distributer tubes, inlet and outlet tubes &c. not required to be in contact with the heat transferring fluids may be inserted (Fig. 8, not shown).
