Abstract
Abstract Refractory ceramic fiber blanket modules with a continuous strip of ceramic fiber material folded into a number of layers in a serpentine fashion are used to insulate high temperature equipment. The blanket is supported by support structure which penetrates the blanket in the vicinity of folds near the furnace wall, providing increased strength against tearing away of the blanket from the supports.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
208 words
Attachment hardware adapted for mounting an insulation module on one surface of a furnace, said module having a hot face and a cold face which between them define a module thickness, a pair of side faces which between them define a module length, and a top face and a bottom face which between them define a module width, said hardware comprising: suspension arm means extending along some portion of the length and width of the cold face of the module, said suspension arm means having a plurality of suspension tabs extending from the cold face toward the hot face for some predetermined distance into the thickness of said module intermediate said two side faces; at least one set of aligned apertures in said suspension tabs; support bar means extending longitudinally through at least some portion of the length of the module, said support bar means being received in said at least one set of aligned apertures in the plurality of suspension tabs and penetrating said module, said portion of the length of the module being less than the full length whereby said suspension tabs and said support bar means are fully contained internally of said module; and means for securing said suspension arm means to said furnace wall.
