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.

A precast refractory block for a coke oven having high hot strength and stable under-load expansion/shrinkage behavior at high temperatures. Specifically, a silica-based precast refractory block contains a P.sub.2O.sub.5 component in an amount of 0.3 to 2.0 mass %.

Coke oven wall structures are provided with a pair of interconnected opposed first and second block components, each of which is generally an asymmetrical T-shaped unitary structure having an interior wall element integrally formed at substantially a right angle to a side wall element. The interior wall element of each of the first and second block components includes a terminal end defining reverse mirror images of respective L-shaped notches which establish corresponding protruding finger elements. In such a manner, each of the protruding finger elements of the first and second block components is received within the L-shaped recesses of the second and first block components, respectively, when such components are positioned in opposition to one another.
