  • Patent number: 11845897
    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.

  • Patent number: 11680208
    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.
