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

The present technology relates to systems and methods for reducing leaks in a system for coking coal. For example, some embodiments provide systems and method for treating a cracked or leaking surface in a system for coking coal. In particular, the present technology includes systems having one or more substances configured to reduce an airflow through one or more cracks by creating an at least partially impermeable patch. The present technology further includes methods for treating surfaces having one or more cracks to reduce an airflow through the one or more cracks.

A system and method for repairing a coke oven having an oven chamber formed from ceramic bricks. A representative system includes a insulated enclosure insertable into the oven chamber and includes removable insulated panels that define an interior area for workers to work in. The insulated enclosure is movable between an expanded configuration and a compact configuration and moving the enclosure to the expanded configuration will decrease the distance between the insulated enclosure and the walls of the oven chamber. Removing the panels exposes the ceramic bricks and allows workers within the interior area to access and the bricks and repair the oven chamber while the oven chamber is still hot. A loading apparatus lifts and inserts the insulated enclosure into the oven chamber. The insulated enclosure can be coupled to additional insulated enclosures to form an elongated interior area.

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.
