ABSTRACT:
Double heating flues are arranged transversely to the horizontal axes of coke oven chambers within heating walls therefor. Side walls between each double heating flue have an internal passageway in the lower part communicating by exit orifices at vertically-spaced locations with the heating flues at the opposite sides of the side wall. The lower parts of the side walls converge horizontally into side wall portions some of which abut against the vertical heating wall and others extend through the vertical heating wall in an alternating arrangement of superimposed bricks. The upper parts of the side walls extend into load-bearing contact with the roof for the coke oven chambers. In the heating walls, three identical stretcher bricks in each course interlock by tongue-and-groove abutment joints. The middle brick abuts in a symmetrical relation with a flue side wall. Pairs of regenerators extend horizontally below each coke oven chamber with one regenerator of each pair alternately preheating air for combustion and receiving burnt gases while the second regenerator of each pair alternately receives burnt gases of combustion and preheats lean gas or preheats air for combustion when heating with rich gas. A dividing wall between each pair of regenerators includes rich gas feed ducts extending vertically to rich gas burners arranged in the heating flues. A rich gas burner is arranged closely adjacent the transverse wall between a pair of heating flues.
