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.
Abstract:
A duct intersection comprising a first duct portion and a second duct portion extending laterally from a side of the first duct portion. At least one flow modifier is mounted inside one of the first and second duct portions. The flow modifier is a contoured duct liner and/or the flow modifier includes at least one turning vane. The duct intersection may also include a transition portion extending between the first and second duct portions, wherein the transition portion has a length extending along a side of the first duct portion and a depth extending away from the side of the first duct portion, wherein the length is greater than a diameter of the second duct portion.
Abstract:
The present technology is generally directed to vent stack lids and associated systems and methods. In particular, several embodiments are directed to vent stack lids having improved sealing properties in a coke processing system. In a particular embodiment, a vent stack lid comprises a first lid portion proximate to and at least partially spaced apart from a second lid portion. The vent stack lid further comprises a first sealing portion coupled to the first lid portion and a second sealing portion coupled to the second lid portion. In several embodiments, the second sealing portion at least partially overlaps the first sealing portion over the space between the first and second lid portions. In further embodiments, at least one of the first or second sealing portions includes layers of tadpole seals, spring seals, rigid refractory material, and/or flexible refractory blanket.
Abstract:
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 he 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.
Abstract:
The present technology is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments, the present technology is applied to methods of coking relatively small coal charges over relatively short time periods, resulting in an increase in coal processing rate. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven.

The present technology is generally directed to coal charging systems used with coke ovens. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, charging plates extend outwardly from inward faces of opposing wings.
Abstract:
The present technology is generally directed to methods of increasing coke production rates for coke ovens. In some embodiments, a coal charging system includes a false door system with a false door that is vertically oriented to maximize an amount of coal being charged into the oven. A lower extension plate associated with embodiments of the false door is selectively, automatically extended beyond a lower end portion of the false door in order to extend an effective length of the false door. In other embodiments an extension plate may be coupled with an existing false door having an angled front surface to provide the existing false door with a vertically oriented face.

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.
