ABSTRACT:
A heating flue for a coke oven includes a flow plate to replace the base in the heating flue. The thickness of the flow plate is greater than the thickness of the flue base and disposed above a chamber which is divided into two halves in a gas-tight manner by a central web of refractory material. Each chamber communicates with ducts that feed preheated air from regenerators during rich-gas firing and feed preheated air and lean gas during firing with lean gas. The height of the chamber to the thickness of the flow plate is a ratio within 0.3 to 0.7, preferably 0.5. The flow plate has a plurality of bores each with a cross-sectional area which, when compared with the cross-sectional area of the plate, forms a ratio of between 20 and 200, preferably 30 to 60. The diameter of a cylindrical bore is between 10 and 60 millimeters, preferably 20 and 50 millimeters.
