A backup thermal insulation plate (41-45, 51-55) includes a colloidal inorganic oxide-impregnated, pressed and dried high-temperature-resistant inorganic-fiber blanket or board, the plate (41-45, 51-55) having a use temperature up to at least about 1000°C and maintaining mechanical integrity after exposure to the use temperature, the plate (41-45, 51-55) having a density greater than or equal to about 500 kg/m3, and a compression resistance of at least about 4900 kPa (50 kgf/cm2). |
