Method for generating a negative pressure in a coke oven chamber during the Ausdrück- and loading process

摘要

The invention relates to a method for sucking off flue gases from a coke oven chamber, wherein the flue gases, which arise briefly during the squeezing and loading process of the coke cake from the coke oven chamber, are sucked off by a generated in the gas space above the coke cake vacuum, and this vacuum in the gas space is generated in an advantageous embodiment in the Sekundärheizraum, which in turn can be sucked by way of example from a vacuum reservoir, the for the duration of opening the Koksofenkammertüren on the Opening of shut-off devices in the connecting line is connected to the Sekundärheizraum. The inventive method avoids the undesirable emission of flue gases into the atmosphere. The invention also relates to a device with which this method is carried out.
