Abstract:
Methods and apparatus for constructing refractory structures, e.g., glass furnace regenerator structures and/or glass furnace structures having walls formed of refractory block and buck stays externally supporting the walls are provided. Opposed pairs of supports are connected to at least a respective one of the vertically oriented buck stays with cross-support beams spanning the refractory structure between a respective pair of the supports. An overhead crane assembly is supported by the cross-support beams. In such a manner, refractory components of the refractory structure (e.g., refractory wall blocks and/or refractory checker bricks) may be installed using the overhead crane assembly.
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).
Abstract:
Refractory checker brick modules for glass furnace regenerators are provided which include multiple preformed refractory checker bricks (e.g., tubular checker bricks, cruciform checker bricks, interweave checker bricks, interlock checker bricks, pigeon-hole checker bricks, basket weave checker bricks and the like) stacked in multiple off-set courses to form a honeycomb structure thereof, the checker bricks in the module being bonded to one another by a bonding agent.
Abstract:
Methods and apparatus are provided for constructing refractory structures, e.g., glass furnace regenerator structures and/or glass furnace structures formed of refractory components, by positioning opposed pairs of vertically oriented base beams on respective opposite sides of the refractory structure and having a lower end rigidly attached to a foundation of the refractory structure and an upper end which extends vertically above the refractory structure, and attaching cross-support beams to respective ones of the base beams at the upper end thereof so as to latitudinally span the refractory structure. An overhead crane assembly may thus be supported by the cross-support beams.
Abstract:
Methods and apparatus are provided for constructing refractory structures, e.g., glass furnace regenerator structures and/or glass furnace structures formed of refractory components, the refractory structure being housed within a building having a roof support elements. Cross-support beams are provided to latitudinally span the refractory structure and are suspended from roof support elements associated with the building housing the refractory structure by a suspension support system attached to the cross-support beams. An overhead crane assembly may thus be supported by the cross-support beams.
Abstract:
Refractory components (e.g. crown or rider arches associated with a refractory structure such as coke ovens, glass furnaces, regenerators and the like) are provided by multiple refractory members bonded to one another by a bonding agent to form an integral self-supporting structure.
Abstract:
Glass furnace regenerators having opposed pairs of side and end walls formed of refractory blocks, a crown arch assembly forming an arched roof of the regenerator, and a rider arch assembly forming an interior floor of the regenerator are provided, wherein at least one of the crown arch assembly and rider arch assembly is formed of adjacently positioned one-piece monolithic pre-cast structures of refractory materials.
