Abstract
Glass furnace regenerators having opposed pairs of side and end walls formed of refractory blocks, wherein at last one of the side and end walls of the regenerator comprise an interlocking plurality of refractory blocks, and wherein the refractory blocks are self-supporting and load-bearing one-piece pre-cast structures of a refractory material. Tie back bars may be provided to operatively connect a wall formed of the refractory blocks to externally provided buckstays to allow relative movement between the refractor blocks forming the wall and the buckstays (e.g., as may be required due to the blocks undergoing thermal expansion during use).
Claims18
A glass furnace regenerator comprising:
- opposed pairs of side and end walls, wherein
- at least one of the side and end walls of the regenerator comprises an interlocking plurality of refractory blocks each having a dimension of about 25.59 inches (650 mm) or greater and a weight of more than about 50 pounds (22.68 kilograms), and wherein
- the refractory blocks are self-supporting and load-bearing one-piece pre-cast structures of a refractory material, wherein the refractory blocks have an air permeability of between about 5×10−15 to about 5×10−14, and wherein
- the refractory blocks comprise longitudinally adjacent integral interior and exterior block regions adjacent an interior and exterior of the regenerator, the interior and exterior block regions being formed of dissimilar precast refractory material having respective thermal conductivity properties that differ by at least about 10% so as to establish a gradient of thermal insulation properties from the interior block region to the exterior block region.
