Claim:
A device for feeding primary combustion air required to burn coking gas in a coking chamber above the coal inventory of a coke oven of the “Non-Recovery type” or “Heat-Recovery type”, comprising: at least one oven chamber, each of the at least one oven chambers having a ceiling: the ceiling of each oven chamber is provided with a plurality of feed openings for primary air, the feed openings being arranged such that coking gas obtained during the coking process comes, in the coking camber, into contact with the desired quantity of primary air in a uniform manner; the feed openings for primary air are grouped above the oven for each oven chamber and are on one hand connected to air feed lines so that a separate feed can be operated through a feed opening via an air feed line; the air feed lines of the individual oven chambers are on the other hand connected to a common air supply header system; and one control device each is installed in the feed openings between the common air supply header system and the individual air feed lines of the oven chambers so that the primary air quantity can be adjusted via the control devices for a variation of the coking period.
