Abstract: Production systems and methods for producing pellets or pellet products, which can be used, e.g., in an electric arc furnace (EAF) to produce metal alloys, are disclosed herein. In some embodiments, a method for forming coke pellets includes (i) blending biomass with a set of materials to form an input blend, (ii) preconditioning the input blend by hydrating the input blend to generate a first plurality of particles, (iii) charging the first plurality of particles into an oven to produce a second plurality of particles via pyrolysis, (iv) post-conditioning the second plurality of particles to produce a third plurality of particles by exposing the second plurality of particles to at least one of an amphipathic binder, a hydrophobic binder, or a hydrophilic binder, and (v) physically altering the third plurality of particles to form coke pellets. The biomass can have a first volatility and the set of materials can have a second volatility lower than the first volatility.

Abstract: Methods and systems for coking coal blends to produce foundry coke products are disclosed herein. Methods for producing coke products can include charging a coal blend into a coke oven; and heating the charged coal blend such that a crown temperature of the coke oven is greater than a lower bound coking temperature. The pyrolysis duration begins when the crown temperature of the oven is greater than the lower bound coking temperature, and ends when the crown temperature of the oven is less than the lower bound coking temperature.

Abstract: Mixture products containing charred products and coal or coke, and associated systems, devices and methods are disclosed herein. The charred product components of the mixture products can be made by receiving an input material in an oven, and heating the oven containing the input material to a predetermined temperature of at least 900° F. for a predetermined time of no more than 48 hours to produce a charred product. Advantageously, embodiments of the present technology can enable a more efficient mixture product production process. The resulting mixture products can also have higher quality in terms of desired Coke Strength After Reaction (CSR), Coke Reactivity Index (CRI), volatile matter content, ash content, sulfur content, grain size, etc.

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: 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: 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.
