<p>A process is disclosed for regulating the gas pressure in the retort of a coke oven. Pivotable cup valves arranged in the elbows of the ascending pipe are actuated as throttling members according to the pressure curve resulting from gas formation from the coal to be cokefied. Throttling of each individual retort is effected by varying water supply, thus regulating the extent of submersion in water, which, dependent upon the desired retort pressure, can climb from 0 mm to the maximal submersion height limit, and regulation follows actual pressure conditions in the retort of the coke oven. The device has, underneath the elbow (22) of the pipe (23), the throttling member consisting of said pivotable cup (1) which exhibits at least one gap (3). The pivotable cup (1) is formed with different feedings through a water line (33) having a valve (32) which is connected to pressure measuring points (15, 25, 26, 27, 28) via a computer (31) and actuator (18).</p> |
