ABSTRACT:
The heating walls for a battery of coke oven chambers are formed by rows of twin heating flues. Each heating flue includes a crosswall having an internal passageway with exit ports at graduated elevation to form a header flue. The header flues in two adjacent heating walls are connected by a first series of ducts to regenerators that supply preheated air during the heating half-cycle. A second series of ducts extend between other regenerators and exit ports on the sole of the heating flues for conducting preheated lean gas or, optionally, preheated air when heating with rich gas. The ducts of each series alternate from heating wall to heating wall so that the sequence of upgoing and downgoing flues alternates from heating wall to heating wall. In the middle of a heating wall, a flue crosswall has two header flues with exit ports at opposite sides whereby the upgoing flue of each twin flue is located toward the middle of the heating wall during one regenerative half-cycle and toward the ends of the coke oven chamber during the other regenerative half-cycle.
