Abstract
Abstract A furnace lining anchoring and support system in which flexible ceramic fiber insulating blankets, exposed to the furnace atmosphere, are anchored in place by a plurality of elongated hollow retainers positioned about the furnace interior and behind the blankets. The retainers each have a longitudinal slot through which portions of the blankets, together with additional insulation packing, are stuffed into the hollow part of the retainer for capture therein to securely anchor the blankets and thermally shield the retainers from furnace radiant heat.
