Abstract: 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.

Abstract: Systems and apparatuses for cooling flue gases emitted from an industrial facility, such as a coke oven in a coke manufacturing plant. A representative system includes a heat recovery steam generator (HRSG) having a steam generation system that converts liquid feedwater into steam by absorbing heat from the flue gases. The steam generation system includes a plurality of tubes that carry the liquid water feedwater and the steam. Some or all of the tubes include steel and a non-corrosive material cladded to the steel that helps to reduce corrosion caused by the high temperature flue gases and extremely corrosive contaminants within the flue gas that can corrode steel.

Abstract: The present technology is generally directed to systems and methods for optimizing the burn profiles for coke ovens, such as horizontal heat recovery ovens. In various embodiments the burn profile is at least partially optimized by controlling air distribution in the coke oven. In some embodiments, the air distribution is controlled according to temperature readings in the coke oven. In particular embodiments, the system monitors the crown temperature of the coke oven. After the crown reaches a particular temperature range the flow of volatile matter is transferred to the sole flue to increase sole flue temperatures throughout the coking cycle. Embodiments of the present technology include an air distribution system having a plurality of crown air inlets positioned above the oven floor.

Abstract: A coke oven can include an oven body, a foundation, and a plurality of beams separating the oven body from the foundation, A buckstay applies force to the oven body to maintain compression on the oven body during thermal cycling of the coke oven. The coke oven further comprises a spring-loaded compression device, which can include a restraining device, an anchor coupled to the restraining device, and a spring coupled to the restraining device. The anchor can be attached to one or more of the beams, the foundation of the oven, or to a similar compression device on an opposite side of the oven. The spring applies force between the restraining device and the one or more beams or foundation to compress the buckstay against the oven. The force applied by the spring can maintain structural stability of the coke oven over a plurality of thermal cycles.

Abstract: The present technology is generally directed to providing beds of coking material to charge a coking oven. In various embodiments, a quantity of first particulate material, having a first particulate size and bulk density, is combined with a second particulate material, having a second particulate size and bulk density, to define a multi-modal bed of coking material. The multi-modal bed of coking material exhibits an optimized bulk density that is greater than an ideal bulk density predicted by a linear combination of the bulk densities of the individual materials.

Abstract: 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.
