  • Furnace with homogeneous refractory tubular liner
    Patent number: 4209295
    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.

  • Method of making thick-walled refractory fiber modules and the product formed thereby
    Patent number: 4202148
    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. F.
