Abstract: An anchor system including a C-track and a two-pronged anchor capable of installing and holding sheet insulation material on a support surface in a compressed state is described. The method of installation utilizing the anchor system of the present invention provides for both the attachment of the insulation to the support surface and compression of the insulation during a single installation operation. The method involves forming a plurality of folds with the sheet insulation to a desired height followed by the insertion of one prong of the two-pronged anchor through the folds to compress the folds and hold the folds in position. The second prong of the anchor initially serves to aid in the compression of the folds and secondarily serves to connect the compressed insulation to a next layer of folds formed and stacked on top of the already formed folds. The use of a separate attachment means with each fold of the insulation material is not required.

Abstract: Disclosed is a heat insulating module and a method of making the same for use in lining a high temperature chamber. The module has a main body formed of layers of refractory fibers positioned side by side and impaled on at least one rigid tie member spaced inwardly of one lateral edge of all layers with the ends of the tie member secured to one leg of L-shaped mounting members with the other legs thereof extending outwardly beynd the end layers of the module and coplanar with the adjacent lateral edge of said layers. The layers may be interconnected by folding a unitary blanket of fibers and, in either assembly mode, the layers are held snugly compressed by at least one encircling tie band.

Abstract: Disclosed is a heat insulating module for use in forming a lining for a high temperature chamber. The module has a main body formed by a blanket of refractory fibers folded into pleats held compressed against one another by a pair of spaced apart tubular members traversing the opposite end portions of all except the two end layers and spaced inwardly near the cold face of the module. The ends of the tubular members are secured to the upright legs of respective L-shaped mounting members with the other legs thereof lying in a common plane generally parallel to the cold face of the module and anchorable to respective fastener studs securable to the wall of the chamber being insulated.

Abstract: A light-weight thick-walled unitary burner block adapted to embrace a burner installed in the wall of a high temperature furnace. The block is formed of spun refractory fibers accreted by vacuum deposition from an aqueous slurry.

Abstract: A high temperature furnace having an access opening and a thick-walled heat resistant lining comprising at least one homogeneous tubular member of multiple generally-tubular layers of vacuum deposited refractory fibers. Larger furnaces utilize two or more liner tubes in end-to-end abutment. The abutting ends may be rabbeted and internested to assure a heat barrier.

Abstract: A method of making thick-walled heat insulation modules by vacuum accreting ceramic fibers from an aqueous solution onto a mold and the product provided thereby. The dimensionally stable generally rigid modules have a thickness of 3"-8" and a density of 10-12 lbs. per cubic foot and are readily subdivided and/or tailored if desired for overlapping intermeshing assembly to provide a continuous lining for a high temperature chamber withstanding operating temperatures between 1600.degree. and 3,000.degree.
