Abstract
Coke oven corbel structures are provided with a multiple number of stacked refractory slabs defining a corresponding multiple number of tiers of the corbel structure, The multiple number of stacked refractory slabs define a pair of substantially vertically oriented central fuel gas passageways and pairs of combustion air passageways laterally of a respective one of the central fuel gas passageways. A plurality of vertically stacked fuel gas blocks each defining a central fuel gas conduit may be positioned within each of the central fuel gas passageways.

A corbel structure for a coke oven comprising:
- an assembly of a multiple number of stacked monolithic refractory slabs defining a corresponding multiple number of tiers of the corbel structure which define a pair of substantially vertically oriented central fuel gas passageways and pairs of combustion air passageways positioned laterally of a respective one of the central fuel gas passageways, and
- a plurality of vertically stacked fuel gas blocks each defining a central fuel gas conduit positioned within each of the central fuel gas passageways, wherein
- an intermediate one of the monolithic refractory slabs defines a common passageway which includes both an intermediate portion of one of the central fuel gas passageways and an intermediate portion of one of the combustion air passageways, wherein the intermediate portions of the central fuel gas passageway and the one combustion air passageway are conjoined to one another so as to establish the common passageway in the intermediate one of the monolithic refractory slabs.
