Abstract: Treating cooling water in industrial production facilities and associated systems, devices, and methods are disclosed herein. The system can comprise a cooling tower with a first and second cell, each having a housing to receive return water and a sump below to maintain supply water configured to directly contact molten metal. The system includes an inlet and an inlet line to provide return water to the cooling tower and an outlet and an outlet line to direct supply water back to the industrial production facility. The inlet, outlet, and cooling tower form a closed-loop network. Additionally, a blowdown line is fluidically coupled to the outlet to divert a portion of the supply water away from the closed-loop network.

Abstract: Systems for continuous granulated metallic unit (GMU) production, and associated devices and methods are disclosed herein. In some embodiments, a continuous GMU production system includes a furnace unit, a desulfurization unit, a plurality of granulator units, and a cooling system. The furnace unit can receive input materials such as iron ore and output molten metal. The desulfurization unit can reduce a sulfur content of the molten metallics received from the furnace unit. Each of the plurality of granulator units can include a tundish that can control the flow of molten metallics and a reactor that can granulate the molten metallics to form GMUs. The cooling system can provide cooled water to the reactor. Continuous GMU production systems configured in accordance with embodiments of the present technology can produce GMUs under continuous operations cycles for, e.g., at least 6 hours.

Abstract: Reduced-waste systems and methods for granulated metallic units (GMUs) production are disclosed herein. A representative method can include receiving a first supply of molten iron and producing GMUs by granulating the molten iron poured onto a target material of a reactor. The method can include removing residual fines of the GMUs via a classifier based on a threshold particle size and mixing the residual fines with a second supply of molten iron to produce additional GMUs.

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: 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 describes methods and systems for an improved quench tower. Some embodiments improve the quench towers 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.
