Abstract

A regenerative coke oven battery that produces a coke cake having a low vertical temperature differential throughout its mass. The heating flues are defined by header walls having ducts for air or lean gas and outlet slots incorporated along the vertical length of the header wall which slots connect the ducts with the flues. The flues are combined into groups connected at their upper ends with a horizontal bus channel which communicates by a cross-over duct with a similar horizontal bus channel on the opposite side of a coking chamber.
