摘要
A method for extracting flue gases from a coke oven chamber, wherein the flue gases that develop briefly during the process of discharging and charging the coke cake from and to the coke oven chamber are extracted by a vacuum generated in the headspace above the coke cake. The vacuum in the headspace above the coke oven chamber is generated via channels through the lateral walls of the coke oven chamber or in the coke cake. The vacuum is generated in the secondary heating chamber and, by way of example, can be extracted again from a vacuum supply tank which, for the time that the coke oven chamber doors are open, is connected to the secondary heating chamber by opening shut-off devices in the connecting line. The method avoids the undesirable emission of flue gases into the atmosphere. A device whereby the method can be carried out is also disclosed.
