Abstract
ABSTRACT
Prefabricated insulating block modules are formed from ceramic fiber blankets folded into a plurality of cold and hot face folds.
The folded and compressed insulating blankets are mounted to a support bracket which secures each cold face fold by means of a support rod which in turn is insulated by the blanket from the heat and corrosive gases in the furnace.

Background of the Invention The present invention relates to a rod-anchored, accordion-fold modular refractory fiber blanket for lining a furnace or like equipment.
Several ceramic fiber modular designs for furnace linings presently j exist. Many modules consist of individual strips of refractory fiber :`! blanket stacked edsewise and either cemented to an expanded metal-,! substrate by means of ceramic cement or mortar, or held together by retainer members having a base portion running the length of the individual 0 strips, as exemplified in Sauder, et al U. S. Patent No. 3,940,244 and Balaz, et al U. S. Patent No. 3,832,815. Other known modular designs s are composed of a compressed continuous strip of pleated insulating . blanket with two of the outer pleats (cold face pleats) mechanically '~3 supported by its metal frame. The supports run substantially the 1~ length of the fold or pleat. The module's metal frame allows it to successively attach to the adjacent modules. Once attached, the modules are mounted to the furnace walls using studs or fastening clips affixed , to the walls as exemplified by U. S. Patent Nos. 4,001,996 (Byrd) and 4,103,469 (Byrd).
~' 20 However, problems still exist with certain types of insulation modules. Ceramic fiber blankets and, therefore, the modules made thereof are not mechanically strong and must be handled with great care :~ to avoid tearing. Ceramic fiber blanket material is known to shrink when exposed to temperatures in excess of 2000F. Known modules utilizing -~ 25 blanket of such material for lining of furnaces have encounteredj difficulties caused by said shrinkage of the material. Shrinkage has ~ caused separations between folds within a module and between modules ., ~ .

a. a support bracket having a base portion covering an area in a direction parallel to the folds of an insulating blanket substantially less than the entire area represented by the cold face side of the module and a bracket mounting member and a protected bracket retaining member at each end thereof, b. the insulating blanket folded into a plurality of inner and outer folds, said plurality of outer folds positioned between the retaining members of the support bracket, and c. a fold support rod extending through the outer pluralit~ of folds of the insulating blanket, each end of the fold support rod attached to the bracket retaining member at a respective end of the support bracket.

Case 4422 DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, illustrated is a rod-anchored, accordion-fold, full-lining module to be used for insulating a furnace or other high temperature equipment. The insulating module 10 is preformed from a folded or pleated insulating blanket 12 and a support bracket 20. Folds or pleats 14 and 16 exist at both the hot and cold faces of the module. The support bracket 20 has a base 22, which covers an area in a direction parallel to the folds of the blanket 12 substantially less than the entire area represented by the cold face side of the module, and a protected upturned retaining member 24 and a mounting member 26 at each end thereof. A pleat support rod 30 extends between the retaining member 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.
The cold face of module 10 is defined as that surface of the module which comes into contact with the furnace wall.
The hot face is defined as that surface of the module which is exposed to -the interior of the furnace. Therefore, the module 10 has both ho-t face or inner pleats 14 and cold face or outer pleats 16. The pleat support rod 30 not only holds the ceramic fiber 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. The retaining member 24 is situated between the outer fold and end flap of the module, thereby protecting member 24 from the detrimental effects of the furnace environment. Any conventional means of attachment can be used. However, typically an end-threaded rod will be used so that a nut at each end of the rod 30 will keep the rod secured to the support bracket 20.
' , . . .
C i~ J 4 4 2 2 The fsld2d ceramic fiber insulating blanket 12 is for,r;ed frr~"7 a suitable commercially available ceramic ,iber sher;t such as t,he t~pe known under the trademark Y~OWOOL sold by The Babcock ~ '~1i1cox C5m5^ny.
It should be understood ~hat the particular type of insulating blznket used is selected based on 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 support bracket 20. This compression is calculated to compensate for thermal shrinkage of the blanket material ~i 10 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 to the support rod 30.
j The banding material insures that the folds and end flaps of the modules 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.
- The modular block fiber lining is typically installed in parquet "2 fashion such that adjacent modules are turned 90 before installation.
