Abstract: Studs projecting downwardly from the decking carrying a battery of underjet coke ovens, all received in recesses in support walls which extend only in a parallel direction to the heating walls for the over chambers. Dampers are provided between the studs and the vertical surfaces of the recesses in the support walls for absorbing forces such as those developed during earthquakes which act parallel to the heating walls of the coking chambers. Strip members project downwardly from the decking along the sides of the support walls. Dampers are interposed between the strip members and support walls to absorb forces acting in a direction normal to the longitudinal heating walls of the coking chambers. The decking includes individual decking portions with adjoining boundary surfaces having interlocking projections.

Abstract: This disclosure relates to reinforced support walls arranged to extend transversely of the length of a battery of coke ovens in a cellar for supporting battery decking of underjet coke ovens. Ducts extend in the cellar for supplying gaseous combustion media to the heating flues of the heating walls and control members are arranged in the cellar to control the flow of the combustion media in the individual ducts. A foundation slab includes reinforcement members bonded to reinforcement members within the support walls. Expansion joints, including slip plates, are arranged between the support walls and the battery decking. The decking may include a projection extending downwardly along the center line of the battery for bonding engagement with the support walls.

Abstract: A flue gas collector for coke ovens, particularly regeneratively-heated coke ovens, wherein the base, crown and side walls of the flue gas collector are formed from reinforced concrete in a generally rectangular cross-sectional configuration and are provided with insulating material on their interior surfaces. Additionally, insulating material is disposed between apertures in the flue gas collector and the ends of outlet pipes leading from changeover valves connected to the coke oven regenerators. The insulation is of such nature and thickness so as to insure that the reinforced concrete body of the collector assumes only negligible temperatures throughout, thereby eliminating cracks and leaks in the walls of the collector.
