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.

Device for compensating deviations from a coaxial arrangement of components of a regulating organ to control the gas pressure of a coke oven chamber

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.

Method for operating a coke-oven battery

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. The inflow-side end of the outflow pipe is surrounded by a siphon pipe which closes the outflow pipe on the top side and which forms an annular duct for the inflow of water, this annular duct issuing into the immersion cup below the immersion pipe.
