Abstract
Vertical heating flues between adjacent coke oven chambers include rich-gas burners extending essentially to progressively increasing elevations in the flues in a manner such that the burner exit zones increase from flue-to-flue to a maximum elevation at the pusher side of each oven chamber. At the pusher side, the coke oven chamber has a minimum width which increases to a maximum width at the coke side where the rich-gas burners have exit zones at the lowest elevation in the heating flues. Such a rich-gas burner arrangement may additionally include rich-gas burners with exit zones at the soles of alternate heating flues while the remaining heating flues contain the burners extended to progressively increasing elevations. When the coke oven chambers are heated by twin-heating flues, the rich-gas burners extend vertically from the soles of only one heating flue in each of the twin-heating flues.
