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.
