  • Patent number: 10190052
    Abstract: A device and a method are provided for regulating and controlling 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 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. 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 different immersion depths of the immersion pipe and the constant water level in the immersion cup.
