Definitions
- the present invention relates to thermally insulative modules for lining furnaces or like equipment.
- Ceramic fibre blankets and, therefore, the modules made thereof are not mechanically strong and must be handled with great care to avoid tearing.
- Ceramic fibre blanket material is known to shrink when exposed to temperatures in excess of 1093°C (2000°F).
- Known modules utilising blankets of such material for lining of furnaces have encountered difficulties caused by said shrinkage of the material. Shrinkage has caused separations between folds within a module and between modules themselves, thereby exposing the furnace shell and critical retainer members to the heat of the interior of the furnace. Shrinkage has also caused the pleats of a folded blanket configuration to unfold and hence sag since not all cold faced pleats were supported.
- US Patent No. US ⁇ A ⁇ 4 287 839 discloses a thermally insulative module for lining a furnace, the module comprising an insulative blanket folded into a plurality of inner folds and outer folds, a support means having a base and a mounting means and a retaining means at each end thereof, the plurality of outer folds of the blanket being positioned between the retaining means of the support means, and fold support rod means extending through the plurality of outer folds of the blanket and attached to the retaining means.
- Such a module is referred to hereinbelow as "a module of the kind described in US ⁇ A ⁇ 4 287 839".
- the base portion of the support means of the module of US ⁇ A ⁇ 4 287 839 is in the form of a base plate whose length and width are substantially the same as the length and width of the module.
- the mounting means at each end of the support means comprises a pair of hooks rotatably mounted to the base plate.
- the retaining means at each end of the support means comprises a pair of lugs that are spaced apart in the direction of the width of the module and are bolted or otherwise fixed to the base plate.
- the lugs are disposed externally of the folded blanket.
- the fold rod support means comprises two fold support rods that are spaced apart in the direction of the width of the module. Each rod is fixed at each end to a respective one of the two lugs at each end of the module.
- the pres nt invention provides a module of the kind described in US-A-4 287 839, characterised in that:
- each bracket mounting member is end-slotted or has at least one hole therein, especially if the slots or holes are sized to accept threaded studs for mounting the module to a furnace or like equipment.
- the simplicity can further be enhanced if a bracket mounting member comprises an elongate integral extension of the elongate base and/or if a bracket retaining member is integral with the elongate base.
- the upturned bracket retaining member at each end of the elongate support bracket is protected by virtue of its being disposed between an outer fold and an end flap of the blanket.
- the retaining members (as well as the fold support rod) is protected from the environment of the furnace or like equipment by virtue of its being disposed within the body of material defined by the folded blanket.
- Modules forming preferred embodiments of the present invention and described hereinbelow can be used to line furnace walls and ceilings.
- the modules can be attached to a furnace wall or ceiling having threaded studs and/or other fastening devices.
- the blanket of the preferred modules is under compression before and after installation. The preferred modules resist unravelling and/or lamination of the layers of insulative blanket.
- FIG. 10 Each figure of the drawings illustrates a rod- anchored, accordion-fold, full-lining thermally insulative module 10 to be used for insulating a furnace or other high temperature equipment.
- the module 10 is preformed from a folded or pleated ceramic fibre insulating blanket 12 and a support bracket 20. Folds or pleats 14 and 16 exist at the hot or inner and cold or outer faces, respectively, of the module 10.
- the support bracket 20 has a base 22, and also has a protected upturned retaining member 24 and a mounting member 26 at each end thereof.
- a pleat support rod 30 extends between the retaining members 24 of each support bracket 20.
- the rod 30 is threaded perpendicularly through each cold face pleat 16 and is located near the outer or cooler face of the module 10 and parallel thereto.
- the outer or cooler face of the module 10 also referred to as the cold face, is defined as that surface of the module which comes into contact with the furnace wall.
- the hot face of the module 10 is defined as that surface of the module which is exposed to the interior of the furnace. Therefore, the module 10 has both hot face or inner folds or pleats 14 and cold face or outer folds or pleats 16.
- the pleat support rod 30 not only holds the ceramic fibre blanket 12 in compression, but also serves to retain each pleat 16 within the module 10.
- Each end of the pleat support rod 30 is attached to a support bracket retaining member 24.
- Each retaining member 24 is situated between an outer fold and end flap of the module, whereby the member 24 is protected from the detrimental effects of the furnace environment. Any conventional means of attachment can be used.
- the rod 30 will typically be end-threaded so that a nut at each end of the rod will keep the rod secured to the support bracket20.
- the folded ceramic fibre insulating blanket 12 is formed from a suitable commercially available ceramic fibre sheet such as the type known under the trademark KAOWOOL and sold by The Babcock & Wilcox Company. It should be understood that the particular type of insulating blanket used is selected in accordance with the range of temperatures in the high temperature equipment in which the apparatus is to be installed.
- the folded blanket 12 is compressed prior to being placed within the support members 24 of the support bracket 20. This compression is calculated to compensate for thermal shrinkage of the blanket material that occurs during use of the module.
- Banding material (not shown) is then placed around the module 10 at or near the two ends so that the banding material is in parallel relationship with the support rod 30. The banding material ensures that the folds and end flaps of the module remain substantially square and compressed during package, shipping and placement. Once installation of the furnace wall or ceiling is complete, the banding material is removed.
- a modular block fibre lining formed from a plurality of the modules 10 is typically installed in parquet fashion such that adjacent modules are turned 90° before installation.
- the present modular design represents a full furnace lining and as such can be used alone. However, if desired, a safety or backup liner layer of wallpaper insulation blanket can be used behind the module as further protection for the furnace shell.
- the mounting members 26 are end-slotted.
- the mounting members 26 may instead each have at least one hole therein.
- the members 26 are preferably sized to accept threaded studs (not shown) mounted to the furnace.
