The present invention relates to a device and a method for regulating and controlling the individual gas pressure of individual ovens of a coke oven battery, in the case of which a rising- pipe bend projects, preferably from above, into a collecting main. The lower end thereof is associated with an immersion pipe via a water labyrinth seal. The immersion pipe is supported such that it is vertically adjustable by means of an actuator, and an immersion cup is located preferably below the immersion pipe. The device aims at allowing the gas pressure to be regulated or controlled easily and reliably. This is accomplished in that the rising-pipe bend has arranged therein a sleeve, the lower end of which is connected via at least one conduit to the water labyrinth seal, and in that a water supply for feeding the water labyrinth seal, and the actuator are provided at the top, outside the rising- pipe bend. Regulation of the gas pressure is accomplished by the different immersion depths of the immersion pipe and the constant water level in the immersion cup. The plane overflow edge of the immersion cup improves the regulating characteristics and the flowing off of the gas and defines the constant water level. |
