Abstract
A method for the automatic removal of carbon deposits from the oven chambers and flow channels of non-recovery and heat-recovery coke ovens, where a coke oven battery, composed typically of a plurality of adjacently arrayed coke oven chambers, is utilized for the cyclical coking of coal, and where an air metering device which operates with superatmospheric pressure is used in order to remove, by combustion, carbon deposits in the flow cross-sections of the oven system and thereby to counteract a reduction in oven performance. An apparatus with which this method can be performed is also disclosed, this apparatus being integrated into the coke oven battery and at least one coke oven chamber wall, allowing the carbon deposits to be removed during operation without a change in any arrangement.
