Definitions

  • ABSTRACT Compensator section for a pipeline for carrying hot fluid, including several expandable portions and a double walled tube, each wall of which having rigid end portions, a rigid middle portion and two longitudinally extensible portions separating the respective extreme portions from the middle portion, and a chamber defined by the double walled tube for the circulation of cooling fluid between the two walls thereof.
  • This invention relates to a compensator section for a pipeline which carries hot fluid, and especially relates to a compensator in a refractory lined blow line or hot air main which connects the ring main for the preheated air blast of a blast furnace to a tuyere.
  • the object of the invention is to provide a compensator section for a pipeline, especially a hot air main which is inserted in the pipeline by means of flange connections (e.g. between the hot blast ring main on one side and the blow bend on the other side) and nevertheless ensures, some independent movement of the two connected points.
  • the compensator section includes a double-walled pipe constituting a length of the pipeline, each wall of the double wall having two rigid end portions, a rigid intermediate portion and two longitudinally expansible portions separating the respective end portions from the middle portion, there being circulating space for cooling fluid between the two walls of the double wall.
  • the invention also relates to a pipeline, especially a hot air main, including such a compensator section.
  • FIGURE shows a longitudinal section of the embodiment which is in a hot air main of a blast furnace.
  • a tuyere cooler 3 Feeding the tuyere is a blow pipe 5 which is joined to a branch 9 of a hot blast ring main (not shown) by means of a blow bend 6, a conical pipe section 7 and a compensator section 8.
  • a drawrod 10 carries the blow bend 6 on the wall 1 of the blast-furnace, the extension of the line of the drawrod 10 passing through the intersection of the centerlines of the blow pipe 5 and the blow bend 6.
  • This drawrod 10 also supports the blow pipe 5 against vertical movements, so that it is possible to exchange the concave-convex connection between the tuyere 4 and blow pipe 5 as desired by any other suitable connection such as a flange connection or a bayonet-catch connection.
  • the hot air main is lined with refractory material throughout its length.
  • expansible and compressible connecting piece or compensator section 8 To accommodate thermal expansion during operation of the furnace and also to make possible limited variations of the dimensions of the hot air main in the course ofoperation of the furnace, there is provided the expansible and compressible connecting piece or compensator section 8.
  • the compensator 8 has flanges 24, 11 at its ends by which it is united to the adjoining sections 7, 9 of the hot air main. Between the flanges the compensator 8 has a double-walled pipe constituted by an inner wall 12 and an outer wall 19 radially spaced therefrom with a circulating space 18 for cooling fluid between them.
  • the inner wall has cylindrical rigid end portions which are rigidly secured to the flanges 24, 11 and two longitudinally expansible portions constituted by bellows l3, 14 of transversely-corrugated sheet, which are separated by a cylindrical rigid intermediate portion.
  • the outer wall 19 likewise has cylindrical rigid'end portions fast with the flanges 24, 11, a cylindrical rigid intermediate portion and two longitudinally expansible portions constituted by bellows 16, 17 of corrugated sheet in which the corrugations run transversely, i.e. circumferentially.
  • the bellows 16, 17 sealingly connect the intermediate rigid portion to the respective rigid end portions.
  • the two rigid intermediate portions of the inner and outer walls 12, 19 are connected by a plurality of radial members.
  • the inner wall 12 is thus lined throughout.
  • the central part of the compensator i.e. the two intermediate rigid portions, are supported by the refractory lining and by the bellows l3, l4, l6, 17.
  • the outer wall 19 is protected by a cylindrical jacket 22 which at one end is rigidly secured to the upper end portion of the wall 19. At its other end it is capable of limited free movement with respect to the lower end portion of the wall 19, their relative longitudinal movement being limited by stops 23 on the wall 19.
  • Cooling fluid to cool the compensator can be circulated by natural or forced flow through the space 18, which is a single chamber.
  • the outer wall has a water inlet connection 20 at its lowest point and an outlet 21 at its highest point for steam formed in the chamber 18.
  • This manner of cooling makes use of the high latent heat of evaporation of water, but simple water cooling (water in and water out) could be used, or cooling by means of pressurized air, suitable connections to the chamber 18 being provided,
  • the cooling fluid contacts the whole of both the inner and outer walls l2, 19.
  • a compensator section for a pipeline for hot fluid including a double-walled pipe constituting a length of the pipeline, each wall of the double wall having two rigid end portions, a rigid intermediate portion and two longitudinally expansible portions separating the respective end portions from the intermediate portion, there being circulating space for cooling fluid between the two walls of the double wall.
  • a compensator section according to claim 1 wherein a protective jacket is arranged outside the outer wall of the double wall, one end of the protective jacket secured to one rigid end portion of the outer wall and the other end moveably maintained on the other end portion of the outer wall for limited relative movecirculating space and a cooling water outlet at the highest point in the said space.
  • a compensator section according to claim 6 having an inlet and outlet to the said circulating space for pressurized cooling air.
