  • Patent number: 8926800
    Abstract: A device for compensating deviations from a coaxial arrangement of components of a regulating organ, said regulating arrangement being comprised of a regulating organ, a crown pipe, and an immersion cup which serve for controlling the gas pressure of a coke oven chamber, with the regulating arrangement being comprised of an immersion cup with a water immersion that seals the gas space of a coke oven chamber versus the gas collecting main and/or plant units downstream, and wherein the height of the water level of the water immersion represents a regulating means to control the gas pressure, and wherein said regulating arrangement is furthermore comprised of an immersion pipe that configures a specially shaped crown pipe at its end submerging into the water of the immersion cup, and that is comprised of a regulating organ to regulate the water level.

  • Publication number: 20120118721
    Abstract: A device for compensating for deviations from a coaxial arrangement of components of a regulating organ for controlling and regulating the gas pressure of a coke oven chamber includes a water inflow into an immersion cup having a water immersion that seals the free gas space of a coke oven chamber versus the exterior atmosphere. The level of the water immersion represents a regulation to control the gas pressure in the coke oven chamber. The regulating arrangement also includes an immersion pipe which at its end is submerged in the water and at this end forms a specially shaped crown pipe. The regulating arrangement also has a regulating organ to control and regulate the water inflow.

  • Patent number: 7097743
    Abstract: A method is provided for operating a coke oven battery including many identical coking chambers, a raw gas receiver, and throttle devices arranged in the receiver for individually controlling the gas pressure in the chambers. Each throttle device includes an immersion bucket acted upon by water. Gas lines terminating in immersion pipes in the immersion buckets connect the chambers with the receiver. Throttle devices are employed that include an overflow that can be vertically adjusted by an actuating drive for controlling the liquid level in the immersion bucket. For a coking chamber to which a pressure control device is allotted, the setting signals for the actuating drive allocated to the time pressure curve in the process of carbonizing coal to coke are recorded as a position-time curve. The actuating drives of throttle devices that are allocated to coking chambers without pressure control devices are controlled according to the position-time curve.

  • Patent number: 7094321
    Abstract: A device for controlling the gas pressure in a coke oven chamber, has an immersion cup, to which water is supplied, and with an immersion pipe which is connected to the gas space of the coke oven chamber and terminates in the, immersion cup. The immersion cup has an overflow and a closeable outflow. To control the liquid level, an outflow pipe for water is provided, the inflow-side end of which projects into the immersion pipe and contains casing-side inflow orifices for the inflow of water. Within the outflow pipe is arranged a slide which is open on both end faces and which closes the inflow orifices of the outflow pipe in the longitudinal direction according to the position of said slide and forms a vertically adjustable overflow for the water flowing into the outflow pipe.

  • Publication number: 20040129553
    Abstract: The invention relates to a device for controlling the gas pressure in a coke oven chamber comprising an immersion cup, which supplies water, and an immersion pipe, which is connected to the gas space of the coke oven chamber and terminates in the immersion cup. The immersion cup comprises an overflow and a closeable drain. The invention provides that, in order to control the level of the liquid, a drain pipe for water is provided whose inlet side end projects into the immersion pipe and whose lateral surface side is provided with inflow openings for admitting water. A slide, which is open on both faces, is placed inside the drain pipe, closes the inflow openings of the drain pipe according to its position in the longitudinal direction and forms a vertically adjustable overflow for the water flowing into the drain tube. The inflow side end of the drain pipe is surrounded by a siphon pipe, which closes the drain pipe at the top and forms an annular channel.

  • Publication number: 20040084293
    Abstract: The object of the invention is a method for operating a coke oven battery comprised of a large number of identical coking chambers, a raw gas receiver, and throttle devices arranged in the raw gas receiver for individually controlling the gas pressure in the coking chambers. The throttle devices each comprise an immersion bucket that is acted upon by water. The coking chambers are connected with the raw gas receiver by gas lines terminating in immersion pipes in the immersion buckets of the throttle devices. According to the invention, throttle devices are employed that comprise an overflow that can be vertically adjusted by an actuating drive for controlling the level of the liquid in the immersion bucket. For a coking chamber to which a pressure control device is allotted, the setting signals for the actuating drive allocated to the time pressure curve in the process of carbonizing coal to coke are recorded in the form of a position-time curve.
