Abstract: 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.

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: The present technology is generally directed to horizontal heat recovery and non-heat recovery coke ovens having monolith components. In some embodiments, an HHR coke oven includes a monolith component that spans the width of the oven between opposing oven sidewalls. The monolith expands upon heating and contracts upon cooling as a single structure. In further embodiments, the monolith component comprises a thermally-volume-stable material The monolith component may be a crown, a wall, a floor, a sole flue or combination of some or all of the oven components to create a monolith structure. In further embodiments, the component is formed as several monolith segments spanning between supports such as oven sidewalls. The monolith component and thermally-volume-stable features can be used in combination or alone. These designs can allow the oven to be turned down below traditionally feasible temperatures while maintaining the structural integrity of the oven.

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: 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.

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: The present technology describes methods and systems for an improved quench tower. Some embodiments improve the quench tower's ability to recover particulate matter, steam, and emissions that escape from the base of the quench tower. Some embodiments improve the draft and draft distribution of the quench tower. Some embodiments include one or more sheds to enlarge the physical or effective perimeter of the quench tower to reduce the amount of particulate matter, emissions, and steam loss during the quenching process. Some embodiments include an improved quench baffle formed of a plurality of single-turn or multi-turn chevrons adapted to prevent particulate matter from escaping the quench tower. Some embodiments include an improved quench baffle spray nozzle used to wet the baffles, suppress dust, and/or clean baffles. Some embodiments include a quench nozzle that can fire in discrete stages during the quenching process.
