    摘要： A method of manufacturing a delayed coker drum as used in a refining process to receive coke feedstock as a hot liquid and in which the coke feedstock is cooled and quenched to produce solid coke, the hot liquid causing the drum to initially expand circumferentially and laterally and upon quenching to shrink due to thermal contraction, the circumferential shrinking serving to crush solidified coke and the lateral shrinking causing interface frictional contact between the solidified coke and the vessel sidewall that must be overcome, inducing high level stresses in the drum, including the steps of selecting a plurality of metal plates configured for assembling the drum, and welding the plates together creating welded seams and in which the metal plates are selected to have metallurgical characteristics and thicknesses such that their elastic limits exceed the stress introduced in the plates during the quenching process and employing welding materials and techniques such that the elastic limits of the welded seams exceed the stress introduced in the seams as the drum shrinks circumferentially and laterally during quenching operations.

    摘要： A coke-oven door for a horizontal coking chamber has a metallic body with an inner surface covered by a thermally insulating layer and a metal plate mounted with the aid of vertically separated spacers on that inner surface. The plate consists essentially of a multiplicity of sections longitudinally adjoining or overlapping one another with limited mobility to facilitate relative thermal expansion. Each spacer comprises a first member secured to the door body and a second member coupled with an associated plate section, or with two such sections in their region of overlap, these members being interconnected with mutual play and/or with relative adjustability.

    摘要： This disclosure is directed to an economical system for the pyrolysis of municipal solid waste to recover valuable by-products while reducing the putrefaction and bulk of the residue requiring disposal. Prior to this treatment, the solid waste has been processed to remove most of the metallic components, and shredded, which steps are not part of the invention disclosed. The pyrolysis and by-product recovery technology is complicated by (a) the inherent variability of the chemical and physical characteristics of the shredded solid waste as received at the pyrolysis plant and (b) the relatively low heat value of said waste as thus received. This pyrolysis and product recovery system includes an improved pyrolysis retort indirectly heated principally by combustion of the least desirable by-product, the solid char, in combination with a furnace for the char combustion, a condenser for the pyrolysis vapor including means for gravity separation of the gas, liquid and solid residues entrained therein, and improved means for conveying the materials through the system including intermittently driven rams for delivering solids into the retort and furnace.

    摘要： 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.

    摘要： The cycle time for a delayed coker unit is reduced by externally heating the coke drum near the junction of the drum shell and the supporting skirt thereof prior to beginning the hot coker feed fill step. This reduces the thermal stresses at the area around the welds of the drum skirt.
