Definitions

  • the cooling stave of the blast furnace body is used to protect the furnace shell, provide cooling, support brick lining refractory material and maintain a proper furnace shape.
  • the heat of refractory material is transferred to the cooling stave base, and the base transfers heat to a pipe carrying cooling water.
  • the cooling water takes heat out of the furnace.
  • One failure mode occurs when the pipeline fractures in the heat load.
  • a first aspect of the application describes a repair method for a cooling stave utilized in a blast furnace, the cooling stave having a stave inlet outlet pipe attached to the cooling pipe in the cooling stave, the method comprising of the steps of: inserting a rigid pipe into the compromised stave inlet outlet pipe to form a first annulus; inflating a bladder disposed inside the inner pipe and cooling stave; injecting a first uncured epoxy material into the first annulus; permitting the first uncured epoxy to cure; and removing the bladder.
  • a first end of the inner tube distal to the stave further comprises a means for introduction of the first uncured epoxy to the first annulus
  • a second end of the inner tube proximal to the stave further comprises means for venting air displaced during injecting of a first uncured epoxy into the first annulus.
  • the repair method further comprises the steps of: applying an outer pipe external to the compromised stave inlet outlet pipe to form a second annulus; injecting a second uncured epoxy material into the second annulus; and permitting the second uncured epoxy material to cure.
  • the first and second uncured epoxies are cured concurrently.
  • the first uncured epoxy is cured before the second uncured epoxy is cured.
  • a first end of the outer tube distal to the stave further comprises a means for introduction of the second uncured epoxy to the second annulus
  • a second end of the outer tube proximal to the stave further comprises a boot adapted to form seals with the outer tube and the stave, and the second end having an aperture in open communication with the second annulus
  • a second aspect of the application describes a repair method for a cooling stave utilized in a blast furnace, the method comprised of the steps of: rethreading an aperture in the cooling stave formed after removal of a compromised stave inlet outlet pipe; installing a new inlet outlet pipe; inserting an inner rigid pipe into the new stave inlet outlet pipe to form an annulus; inflating a bladder inside the inner rigid pipe and the cooling stave; injecting an uncured epoxy material into the annulus; permitting the uncured epoxy to cure; and removing the bladder.
  • a third aspect of the application describes a repair system kit for a cooling stave utilized in a blast furnace, the cooling stave having a stave inlet outlet pipe comprised of: an inflatable bladder; an inner rigid pipe; a grout inlet; and a vent tube.
  • the repair system further comprises a concentric outer pipe; and a flexible rubber seal.
  • FIG. 1 illustrates embodiments of elements of one aspect of the application.
  • FIG. 2 illustrates further embodiments of elements of the application.
  • FIG. 3 illustrates another aspect of the application.
  • FIG. 4 illustrates existing stave failure mechanisms.
  • FIG. 5 illustrates existing stave failure mechanisms.
  • FIG. 6 illustrates existing stave failure mechanisms.
  • the repair system utilizes an inflatable bladder 20 , a concentric inner rigid pipe 1 , a custom machined grout inlet 7 , vent tube 8 , and compression fitting 3 .
  • inner rigid pipe 1 is inserted into the compromised stave pipe 27 .
  • Inflatable bladder 20 is inserted into the inner rigid pipe 1 as far as stave 30 .
  • the bladder 20 is inflated to a specified pressure and epoxy 15 is injected into the compromised stave inlet outlet pipe 27 and around the inner rigid pipe 1 via the grout inlet 7 in fitting 2 .
  • the epoxy 15 is injected until the entire first annular gap 28 between the compromised stave inlet outlet pipe 27 and the inner rigid pipe 1 is filled.
  • An optional vent tube 10 is positioned in the first annular gap 28 extending beyond the length of the first annular gap 28 allows for displaced air to escape.
  • the epoxy 15 is injected it is cured.
  • the bladder 20 is deflated and removed.
  • the inner rigid pipe 1 is an epoxy pipe.
  • an outer rigid pipe 5 may be positioned around the compromised stave pipe 27 .
  • a grout inlet 7 is formed or attached through the outer rigid pipe 5 .
  • a flexible seal 6 is fitted to an end of the outer rigid pipe 5 .
  • the flexible seal 6 has an optional aperture 31 to allow for escape of displaced air.
  • Epoxy 15 is injected until the entire second annular gap 29 between the compromised stave inlet outlet pipe 27 and the outer rigid pipe 5 is filled. After the epoxy 15 is injected it is cured.
  • the outer rigid pipe 5 is an epoxy pipe.
  • the compromised stave inlet outlet pipe 27 may first be removed from the stave 30 to give a resulting aperture.
  • the resulting aperture is rethreaded and a new inlet outlet pipe is installed in the resulting aperture.
  • the method steps of the first and second embodiments may then follow.
  • stave inlet hoses may be reattached to the epoxy pipe 1 , in a preferred embodiment through an attached connector 4 and elbow 11 and the water circuit tested per plant procedures.
  • a dowel rod 23 and pull rod 25 are used to assist in the insertion and removal of the bladder 20 .
  • a repair system kit for a cooling stave utilized in a blast furnace having a compromised stave inlet outlet pipe comprised of an inflatable bladder 20 , a rigid inner pipe 1 ; a grout inlet 7 ; and a vent tube 8 .
  • the repair system kit may further comprise rigid outer pipe 5 and flexible seal 6 .
  • FIGS. 4-6 illustrate example staves 30 and stave inlet/outlet pipes 27 that may be repaired with the repair system and repair kit of the present application.
  • FIG. 4 illustrates a weld or pipe fracture 50 caused by heating and cooling cycles
  • FIG. 5 illustrates a pipe or weld fracture 50 caused by flow disruptions
  • FIG. 6 illustrates a pipe or weld fracture 50 caused by plug washing.
  • This method of repair allows the customer to reestablish water to a compromised water pipe without losing the cooling effects of the water in contact with the stave.
