A corbel for a coke oven, including a gunblock section having a longitudinal through-bore arranged therein, the gunblock section having at least one substantially vertical though-bore in communication with the longitudinal through-bore. The gunblock section may be integral with a base. The gunblock section may also include a substantially vertical-angular channel open to a first end of the gunblock section and also open to a first side of the gunblock section.

Methods and systems for coking coal blends to produce foundry coke products are disclosed herein. Methods for producing coke products can include charging a coal blend into a coke oven; and heating the charged coal blend such that a crown temperature of the coke oven is greater than a lower bound coking temperature. The pyrolysis duration begins when the crown temperature of the oven is greater than the lower bound coking temperature, and ends when the crown temperature of the oven is less than the lower bound coking temperature.

A flue block for a heating wall of a coke oven battery, the flue block having a proximal end and a distal end, the flue block comprising a first aperture disposed within the flue block, and a riser arranged in said first aperture. The flue block may also comprise a second aperture disposed therein, the second aperture spaced apart from the first aperture, and a second riser arranged in the second aperture. The flue block may be configured such that the riser is arranged to extend past the proximal end of the flue block. The flue block may be also configured such that the first riser extends past the proximal end. The flue block may be further configured such that the second riser extends past the proximal end.
