Integral self-supporting composite refractory wall modules for refractory structures and methods of forming refractory structure walls of the same

1. A refractory structure comprising:

opposed pairs of side and end walls, wherein

the side and end walls comprise a plurality of interconnected integral self-supporting riser wall sections, wherein

each riser wall section comprises a plurality of end-to-end interconnected refractory modules which include multiple preformed square parallelepiped refractory blocks bonded to one another by a bonding agent to form the integral self-supporting riser wall sections, wherein

the refractory blocks of each refractory module are off-set relative to one another so as to establish respective tooth and channel arrangements at opposed ends of the refractory module, wherein the tooth and channel arrangements of one of the refractory modules being interlocked with respective channel and tooth arrangements of other refractory modules adjacently end-to-end interconnected therewith.

2. The refractory structure as in claim 1 , wherein the pre-formed refractory blocks are pressed or cast.

3. The refractory structure as in claim 1 , wherein the bonding agent is a sacrificial or non-sacrificial bonding agent.

4. The refractory structure as in claim 1 , wherein the bonding agent is an epoxy adhesive bonding agent.

5. The refractory structure as in claim 1 , wherein the refractory modules comprise at least three of the preformed refractory blocks that are bonded to one another.

6. The refractory structure as in claim 1 , further comprising a profiled tie plate positioned between adjacent vertically stacked refractory wall sections.

7. A method of forming the refractory structure according to claim 1 , wherein the method comprises:

(i) forming a plurality of refractory wall sections by assembling end-to-end and stacking a plurality of the refractory modules such that the tooth of one module is received within and interlocked with the channel of an adjacent module; and thereafter

(ii) adjacently stacking a plurality of the refractory wall sections to form the opposed side and end walls of the refractory wall structure.

8. The method as in claim 7 , wherein the refractory blocks are pressed or cast.

9. The method as in claim 7 , which comprises prior to step (i) the step of (ia) assembling the refractory modules by bonding multiple preformed square parallelepiped refractory blocks to one another with a bonding agent.

10. The method as in claim 9 , wherein step (ia) comprises positioning adjacent refractory blocks in an off-set manner so as to form the tooth and channel arrangement of the refractory modules.

11. The method as in claim 9 , wherein the bonding agent is a sacrificial or non-sacrificial bonding agent.

12. The method as in claim 11 , wherein the bonding agent is an epoxy adhesive bonding agent.
