Abstract

A coke oven may comprise an upper oven and a lower oven beneath the upper oven. Crude gas produced in a coking chamber of the upper oven during a coking process is incompletely combusted in the upper oven and may subsequently be conducted into the lower oven via downwardly directed downcomer channels. The crude gas may flow through an outer sole flue, may be deflected in a transition region, may flow through an inner sole flue, and may exit the lower oven via an exhaust gas collecting channel. The outer and inner sole flues may be supplied with secondary air such that the gas initially partially combusted in the upper oven by means of primary combustion is completely combusted in the lower oven by means of secondary combustion. The transition region in which the gas is deflected in the lower oven may be divided into a plurality of flow channels.
