Abstract (en)

[origin: ES8204755A1] A method and a device for feeding purging and degraphitizing air into pipes for rich gas leading to the heating walls of coke ovens. In the device a first cross-sectional opening is connected to a pipe for rich gas. This opening can be opened and closed with a first gate and is adapted to initially release only a relatively small cross-sectional aperture for passing purging air therethrough. A second cross-sectional opening is provided in the device, which is connected to the pipe for rich gas. The second opening can be opened and closed with a second gate and is adapted to release successively, with a time delay after the first cross-sectional opening, a relatively larger cross-section for passing degraphitizing air therethrough. An exchangeable screen can be placed in the aperture in the first cross-sectional opening. The degraphitizing air enters the pipe for burning off the graphite deposits resulting from the rich gas. The device and method prevent deflagrations caused by feeding inaccurate amounts of purging air into the pipe for rich gas.

Einrichtung zur Zuführung von Spül- und Entgraphitierungsluft in die zu den einzelnen Heizwänden von Verkokungsöfen führenden Starkgasleitungen. Bei dieser Einrichtung wird zunächst ein vergleichsweise kleiner Öffnungsquerschnitt für die Spülluft und danach ein grösserer Öffnungsquerschnitt für die Entgraphitierungsluft freigegeben. Es ist vorgesehen, dass für die Spülluft und die Entgraphitierungsluft zwei mit Klappen (4, 5) absperrbare Querschnitte angeordnet sind, die in einstellbarem zeitlichem Nacheinander öffnen.
