Systems and methods for removing carbonaceous clinker material from a coke oven are described. A coke oven can be provided including an oven floor, coke, and clinker material deposited on the oven floor. After a temperature of the coke oven has reached a first temperature (e.g., after heating coal in the oven to produce coke), the method includes increasing the temperature of the coke oven to a second temperature that is higher than the first temperature for a predetermined amount of time. After the predetermined amount of time, the temperature is reduced to a third temperature that is lower than the first temperature.

Decarbonization of coke ovens and associated systems and methods

A coke oven includes an oven chamber configured to support and heat a coal bed, a castable slab below the oven chamber, and a foundation supporting the heat recovery oven. One or more beams are positioned between the castable slab and the foundation. The beams extend from a first end of the oven chamber to a second end of the oven chamber, forming a plurality of air gaps between the castable slab and the foundation. Heat from the oven chamber is dissipated by the one or more beams.

Heat recovery oven foundation

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.

Decarbonization of coke ovens, and associated systems and methods

The present technology is generally directed to methods of decarbonizing coking ovens, and associated systems and devices. In some embodiments, a method of operating and decarbonizing a coking oven can include inserting a charge of coal into the coking oven and heating the coal. The method can further include removing at least a portion of the charge, leaving behind coking deposits in the coking oven. At least a portion of the deposits can be continuously removed from the coking oven. For example, in some embodiments, at least a portion of the deposits can be removed each time a new charge of coal is inserted in the coking oven.

Methods for decarbonizing coking ovens, and associated systems and devices

The present technology describes various embodiments of systems and methods for maintaining a flat push hot car. In some embodiments, the flat push hot car includes an at least partially enclosed hot box having an interior portion, an exterior portion, a base, and a plurality of sidewalls extending upward from the base. The hot box can be coupled to or integrated with a fluid distribution system. The fluid distribution system can include a spray manifold having one or more inlets configured to release a fluid directed toward the sidewalls of the interior portion so as to provide regional cooling to the hot box.

Systems and methods for maintaining a hot car in a coke plant

Systems and methods of dynamically charging coal in coke ovens related to the operation and output of coke plants including methods of automatically charging a coke oven using a charging ram in communication with a control system to increase the coke output and coke quality from coke plants. In some embodiments, the control system is capable of moving the charging ram in a horizontal first direction, a horizontal second direction and a vertical third direction while charging coal into the oven. In some embodiments, the coal charging system also includes a scanning system configured to scan an oven floor to generate an oven floor profile and/or oven capacity. The scanning system used in combination with the control system allows for dynamic leveling of the charging ram throughout the charging process. In some embodiments, the charging ram includes stiffener plates and support members to increase the mechanical strength of the charging ram and decrease the sag of the charging ram at a distal end.

Method and system for dynamically charging a coke oven

A method of testing the coking qualities of sample quantities of coal in a test container and the structure of the test container are disclosed. A test container which is ideally reusable is adapted to receive one or more samples of coal to be tested and then the test container is inserted into a coking oven along with additional, conventional coal during a conventional coking operation. Following the completion or substantial completion of the coking operation, the test container is recovered and from the conventional converted coke and the sample(s) of coke are removed from the container for testing and evaluation. The container is recharged with one or more additional samples of coke and reused in another conventional coking operation.
