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.
Claims12
A refractory ceramic fiber blanket module for insulating an inner surface, such as a wall, of a furnace or the like, comprising:
- (a) an insulating blanket folded into a plurality of folds of adjacent layers of refractory ceramic fiber insulating material, said blanket comprising:
- (1) an inner surface portion exposed along an insulation surface to the interior of the furnace;
- (2) an outer surface portion adapted to be mounted against a wall of the furnace;
- and
- (3) side portions formed from said layers and being folded adjacent said inner and outer surface portions to form alternating inner and outer folds;
- and
- (b) means for supporting said blanket on the inner surface of the furnace, comprising:
- (1) support means extending through a plurality of said side portions of said blanket adjacent said outer folds to support said blanket in place;
- (2) suspension means mounted on said outer surface portion of said blanket extending between a plurality of adjacent layers forming an inner fold therebetween for receiving said support means;
- and
- (3) means for attaching said suspension means to the inner surface of the furnace.
