Apparatus and method for setting up a control element for the gas pressure of a coke oven chamber without expansion-induced deviations of the control assembly

摘要

The invention relates to a device for setting up a control element for controlling the gas pressure of a coke oven chamber without expansion-induced deviations of the control assembly, which deviations in comparable devices from the prior art result from high temperatures and temperature differences in coke oven chambers during operation. The device according to the invention and the method prevent water used for shutting off, cooling and removing water-soluble impurities from riser pipes from flowing out of the control element in an uncontrolled manner. The invention also relates to a method for controlling the gas pressure of a coke oven chamber using said device, wherein the pressure in the coke oven chamber relative to the collecting main conducting raw gas is controlled by using said control element without expansion-induced deviations of the regulating assembly.
