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.

Abstract: Coke oven corbel structures include an assembly of multiple stacked tiers of refractory blocks defining a plurality of substantially vertically oriented central flues and a plurality of diagonally oriented lateral flues. At least one tier of refractory blocks in the assembly includes by an alternating plurality of saddle blocks and central diagonal flue blocks. The saddle blocks may include a laterally opposed pair of upright columns which define therebetween a rectangular channel, and a substantially vertically oriented cylindrical flue extending from a bottom surface of the saddle blocks to the rectangular channel thereof. The central diagonal flue blocks may include an arcuately concave flue channel defined between top and bottom surfaces thereof so that an upper opening to the flue channel at the top surface is inwardly offset relative to a lower opening thereof at the bottom surface.

Abstract: Coke oven corbel structures include an assembly of multiple stacked tiers of refractory blocks defining a plurality of substantially vertically oriented central flues. A first tier of refractory blocks in the assembly includes a series of lower cradle blocks defining respective lower semi-circular surfaces extending from one end to another end of the corbel structure. A second tier of the refractory blocks in the assembly includes a series of upper crown blocks defining respective upper semi-circular surfaces extending from one end to another end of the corbel structure. At least one set of the upper crown blocks in the second tier of refractory blocks defines respective substantially vertical segments of the vertically oriented central flues of the corbel structure which is in fluid communication with a cylindrical channel of the corbel structure.

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, 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 modules are provided by multiple preformed refractory blocks bonded to one another by a bonding agent to form an integral self-supporting structure having a tooth and channel arrangement for interlocking assembly with a similar adjacently positioned refractory module.

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: Coke oven corbel structures include an assembly of multiple stacked tiers of refractory blocks defining a plurality of substantially vertically oriented central flues and a plurality of diagonally oriented lateral flues. At least one tier of refractory blocks in the assembly includes a plurality of tongue-and-groove interconnected refractory blocks. This plurality of interconnected refractory blocks of the at least one tier comprise mutually substantially orthogonal faces defining an edge and respectively including an elongate tongue protruding outwardly therefrom and an elongate groove recessed therein. The elongate tongue and groove include respective adjacent ends which co-terminate with one another at the edge defined by the mutually orthogonal faces of the refractory blocks.

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.

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.
