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.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.
