Abstract: An insulation module, for the interior of furnaces and the like, in the form of layers of ceramic fiber blanket is provided with attachment structure which facilitates installation. The attachment structure permits ease of installation and provides a perceptible indication once the module is properly attached to the furnace wall.

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.

Abstract: Refractory ceramic fiber blanket modules with a continuous strip of ceramic fiber material folded, such as 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. The attachment structure of the module permits the module to be installed on non-planar or curved surfaces as well as planar or flat surfaces.

Abstract: Fluid containing support members of walking beam mechanisms for moving beams and the like in furnaces are insulated with refractory ceramic fiber blanket modules. The modules are wrapped about the support members and attched with attachment members. Protective coverings are provided to reduce exposure of the fiber materials from slag from the beams.

Abstract: Refractory fiber blanket blocks for electric furnaces having electrical heating elements mounted therewith by supports provide substantially improved insulation capabilities for electric furnaces when attached to the furnace walls. The support elements are in the form of holder members for receiving and support heating elements of the electric furnace and an arcuate spearing member which is capable of insertion into the insulative block at any desired location on an inner surface or hot face without requiring any anchoring structure for heating element support. The arcuate spearing member may take several forms and supports the heating element, engaging only the fiber blanket without anchoring structure for support.

Abstract: Gaps or seams between adjacent modular refractory fiber blanket insulation modules are filled by inserting therein strips of refractory fiber blanket. The strips are bent into a U-shape over a blade or plate and then inserted between two spreader members, called lubricators, to overcome the tendency of the blanket in the strip to adhere to the blanket in the module.

Abstract: Existing refractory fiber blanket furnace lining systems receive a layer of high temperature ceramic fiber blanket or felt on an inner surface portion, or hot face, thereof exposed to interior conditions of the furnace. The layer is attached to the module by being sewn thereto with continuous filament ceramic fiber thread. The layer can be added to increase insulation capacity on lower temperature furnace insulation or to repair damaged insulation in a furnace.

Abstract: Modular fiber blanket furnace lining is covered on the "hot face" with a surface layer of cloth made from continuous fibers of metal oxides (such as of alumina-boria-silica composition) to prevent erosion of the underlying fibers by high velocity furnace gases.

Abstract: A refractory fiber blanket furnace lining module with compensation for heat shrinkage, and method of assembly of such a module, are disclosed. In the module as assembled, the refractory fiber material is in compression in horizontal planes coplanar with the hot face and also in compression in planes vertical to the hot face. Upon or after installation, the horizontal compression is removed so that the fibers may expand to compensate for heat shrinkage as such shrinkage occurs and maintain a seal in joints between adjacent modules.

Abstract: A fiber blanket module having a rectangular or box-shaped frame attached by suitable attachment structure to a wall of a furnace or other high temperature equipment to insulate such equipment. Each of two strips of woven metal oxide fiber cloth is suspended between one set of opposite sides of the frame, forming a pocket. The pocket is filled with suitable insulating material, which includes bulk, unconsolidated ceramic fiber, refractory fiber blankets, and the like.

Abstract: A prefabricated insulating structure is formed from a ceramic fiber blanket, folded into plural folds, for insulating a corner formed by two walls within a furnace. The folded blanket is mounted in a curved configuration to a single attachment mounting such that each of the two ends of the curved folded blanket is adjacent one of the walls at the corner. The folded blanket is mounted to the attachment mounting by two support members, each of the support members being mounted in a fold adjacent one of the ends of the folded blanket.

Abstract: Prefabricated insulating blocks are formed from ceramic fiber blankets folded into plural folds, with adjacent layers being needled together to intermingle the fibers of adjacent layers to form composite blocks. The blankets are mounted to attachment channels by support beams, mounted within folds in the blankets, and the folds of the blanket surround and enclose the support beams to protect them from heat and corrosive gases in the furnace.

Abstract: A new and improved apparatus and method for lining walls of furnaces, and other high temperature equipment, wherein insulating blankets are folded and supports are mounted in the folds thereof for mounting to the furnace wall to insulate the furnace. In some applications, the lining apparatus is formed into preformed insulation blocks for installation as insulating linings.
