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.

Abstract: A coke-oven door has an annular periphery normally juxtaposed with an annular door frame. A seal assembly for the door has at least two flexible, relatively displaceable, metallic, and annular membranes each having an annular inner periphery and an annular outer periphery and a U-section channel fixed to the outer periphery of only one of the membranes, open toward the door, and having annular inner and outer edges. The other membrane bears on the one membrane and therethrough on the channel. A mount secures the inner peripheries of the membranes to the periphery of the door. A spring urges the edges of the channel with a spring force against the door frame.

Abstract: A coke oven has a coke-oven chamber adapted to hold a mass of coke, defining above the mass of coke a gas-collecting chamber, and having a door opening. A door closes the door opening. A peripheral gas channel extends around the opening between the door and coke-oven chamber and has at least one outer and at least one inner door seal defining an annular space. The inner door seal is formed in both the coke-oven chamber and the gas-collecting chamber with a plurality of throughgoing holes forming fluid-communicating connections between the coke-oven chamber, the gas-collecting chamber, and the annular space at different heights of the coke-oven chamber and of the gas-collecting chamber. Thus regions of the coke-oven chamber with different gas pressures communicate with each other and with the annular space via the connections on the inner door seal to equalize pressure between the regions and the gas-collecting chamber.

Abstract: The invention relates to a device for sealing a leveling door aperture of a coke oven chamber when loading bulk coking coal. The device includes a housing and a leveling door aperture, a leveling arm, composed of at least side panels and cross spacers connecting the side panels, is guided through the housing and the leveling door aperture. The leveling arm supports means for sealing a cross-sectional area of the leveling door aperture or upstream the leveling door aperture. A controllable or adjustable exhauster is joined to the housing and a measurement point is provided for flow rate measurement.

Abstract: The invention relates to a coke oven door (1) with a gas channel that substantially encloses the oven door and a membrane that is fastened on the coke oven door (1) and that can be forced against the chamber frame against the action of a spring. The gas channel (5) is fastened on an at least bilayered membrane (3).
