Abstract
1,109,669. Tubular heat exchangers; steam generators. WAAGNER-BIRO A.G. 19 May, 1965 [20 May, 1964], No. 21371/65. Headings F4A and F4S. A heat exchanger comprises helically coiled tubes defining a plurality of telescoped coaxial cylinders each containing one or more tube coils and the tube lengths, which include pipes connecting the tube coils to headers, increase in length with each increase in cylinder diameter, the increase in length diminishing from cylinder to cylinder. In one form (Figs. 1-3) the axial tube spacing is constant and the ratio of number of tubes to cylinder diameter decreases with increasing cylinder diameter. Alternatively the ratio of number of tubes to cylinder diameter may remain constant, the axial tube spacing from cylinder to cylinder decreasing with increasing cylinder diameter. In another form described (Fig. 5) the axial spacing (27) increases with increasing cylinder diameter, the transverse spacing (28) between adjacent cylinders remaining substantially constant. Further arrangements comprise two concentric groups of cylinders one group having smaller diameter tubes than the other (Fig. 7). Alternatively (Fig. 8) these cylinders of smaller and larger tubes may be arranged alternately, and may be superheater and reheater tubes. The drawing shows steam generating plant in which a flow of hot gas (which may be assisted by a fan at the point 57) flows over the tube cylinders. Feed water enters via header 58 and passes through preheater, evaporator and superheater sections 60a, 60b and 60c respectively from which steam flows via header 62 and temperature regulator 63 (e.g. an injection cooler) to a header 64 which conducts the steam to a final superheater 66. Interleaved with the cylinders of tubes 66 are other tube cylinders 73 in which expanded steam from a turbine (not shown) is reheated before passing out at 72 to the low pressure part of the turbine. 75 is a tube supporting structure (not described in detail) from which the tubes are suspended. 74 is a baffle to prevent by-passing of the tubes by the heating gas.
