PATENT OFFICE,
CHARLES E. LUCKE, OF NEW YORK, N. Y., ASSIGNOR TO THE BABCOOK & WILCOX COM PANY, OF BAYONNE, NEW JERSEY, A CORPORATION OF NEW JERSEY GOMIBINED CONDENSER AND HEATER Application filed December 20, 1929. Serial No. 115,385.
trative embodiment of the invention taken along the line 1 1 of Fig. 3; Fig. 2 is a section along the line 22 of Fig. 1; Fig. 3
is an end view taken along the line 33 of Fig. 1, and Fig. 4: is a section on an enlarged scale, partly broken away, showing some of the details.
In the drawing, reference character 1 indicates an elongated casing preferably circular in cross-section that is provided with bumped heads 2 at. opposite ends.
An inlet 3 for vapors is provided on the upper side near the middle and a sump a is provided below the inlet on the lower side. An. outlet 5 for condensate which is provided with a trap 6 leads from the sump 4. The
inner end 7 of the outlet 5 extends slightly above the bottom of the casing 1 so that a certain amount of liquid will be maintained in the bottom 01": the casing.
Concentric circular rows or" curved tubes 8 extend longitudinally of the casing. A space, preferably circular incross-section, is left at the center of the rows of tubes 8, as most clear- 1y indicated in Fig. 3. The tubes 8 are welded, as indicated at 9, to the heads 2 where they pass through these heads and the tubes 8 are curved between the heads 2 to permit rela tive expansion between the tubes and casing. An inlet 10 for fluid that is to be heated is shown connected to the end of one or" the tubes and the ends of the tubes are connected outside of the casing l by means of Y-connections 11 that may have their branches electrically welded to the ends of the tubes 8 by the well-known Thomson process, as indicated at 11. The Y-connections 11 may be provided with removabie plugs 11 so that access to the insides of the tubes 8 may be readily gained. The fluid to be heated passes in series through the tubes and then out through the outlet 12. The joints are all outside of the casing and the tubes inside of the casing are all continuous, so that the danger of leakage is entirely obviated, thereby assuring complete separation between the heating'vapors and the fluid to be heated; Although the tubes 8 are shown connected in series, they may be connected in other ways, so that the flow through these tubes may be in groups of tubes in which the tubes t the groups are in series but the groups themselves are in parallel, orother appropri ate connections of the tubes to each other may be made.
The inside of the casing is provided with a series of annular battles 13 surrounding the tubes 8 and contacting with the inside Walls of the casing. V
Hollow members: 1 1 of the shapes of truncated cones are located in the space between the tubes 8. These members 14 have their ends 15 closed and in line with the baffles 13 nearest the middle of the casing. The other ends ofthe members 14 terminate short of the ends of the casing. V
Annular bafiies 16 surround the members lt and extend across the tubes 8 with their edges spaced fromthe inside walls of the easing 1. Valved outlet pipes 17 for uncondensed gases are provided at the ends of the casing through the heads '2. U-shaped pipes 18 which form traps,,connect the spaces in the casing 1 between opposite sides Of the bafdes 13. A hood 19 that may be supported by some of the tubes 8 by means of the supports 20, is provided'belowthe tubes above the inlet end 7 of the pipe 5.
. The operation is as follows: The fluid to be heated is introduced through the. inlet 10 and passes through the tubes 8 and thence out through the outlet 12. The heating vapors enter through the inlet 3 and pass somewhat-radially across the tubes 8, thence between the members 14: and first baflies 13, thenceover the outer edges of the bafiies 16 and again across the tubes 8, the latent heat of condensation heating the fluid "passing through the tubes 8 and the condensates dripping to the bottom of the casing 1 and then passing out through the outlet pipe 5. The condensates that collect on the other side of the bafiies 13 from the outlet 5 pass through the traps 18 and thence to the outlet.
Any. gases that are non-oondensible at the temperatures in the casing'l that may be present in the vapors are swept forward by the fiow of the vapors and collect in the ends of the casing 1 and can be Withdrawn periodically through the valved outlets 17.
I claim:

2. In a heat exchanger, an elongated casing and curved tubes extending through said casing, the ends of said tubes being farther froin the center line of said casing than intermediate portions of said tubes, and individual tube connections outside the casing inter-relating the tubes for circulation.
3. In a heat exchanger, an elongated casing and curved tubes extending through said. casing, and transverse battles in said casing, and individual tube connections outside the casing inter-relating the tubes for circulation.
4. In a heat exchanger, an elongated casing and curved tubes extending through said casing, transverse bafiies in said casing. and an outlet for uncondensed gases at the end of said casing, and individual tube connections outside the casing inter-relating the tubes for circulation.
5/ In a heat exchanger, an elongated casing and curved tubes extending through said casing, said tubes being arranged in circular rows, and filling members inside of said rows.
6. In a heat exchanger, an elongated casing and curved tubes extending through said casing, said tubes being arranged in circular rows, filling members inside of said rows, and battles between said filling members and easing.
7 In a heat exchanger, a casing, tubes in said casing extending longitudinally therethrough, and ba'flles in said casing to cause gases to pass across said tubes, and individual tube connections outside the casing interrelating' the tubes for circulation.
8. In a heat exchanger, a casing, tubes in said casing extending longitudinally therethrough, and staggered baiiles in said casing extending transversely of said tubes, and individual tube connections outside the easing'inter-relating the tubes for circulation.
9. In a heat exchanger, a casing, tubes in said casing extending longitudinally therethrough, and annular staggered bafiies in said casing extending transversely of said tubes, and individualtube connections outside the casing inter-relating the tubes for circulation.
10. In a heat exchanger, an elongated casing, tubes extending through and fixed in the heads of said casing and each having the form of a catenary bend compensating for relative expansion and contraction of the casing and tubes, said tubes being arranged in concentric rows ithin the casing, an entrance and outlet in the casing for heating fluid, baffies Within the casing passing the gases in a radial direction back and forth over said tubes, and connections outside the casing ends inter-relating the tubes for serial circulation of the fluid therethrough.
