Device for feeding combustion air or gas influencing coal carbonization into the upper area of coke ovens

摘要

Disclosed is a device and a method for feeding primary combustion air for the combustion of coke oven gas into a coking chamber of a coke oven of the non-recovery or heat recovery type, the coke oven is provided with openings in the oven chamber through which the oven chamber can be charged with primary air, and heating flues in the oven chamber sole with openings through which the heating flues can be charged with secondary air, and downcomer-channels which allow for guiding partially burned gas for combustion with secondary air from the oven chamber into the heating flues, wherein in the oven wall above the door or in the upper door area there are one or more non-controlled openings comprised of a heat-proof material through which part of the primary air can be guided, and in the top area of the oven there are further controllable air feeder ducts conducting primary air through the oven top.
