Abstract (en)
[origin: US2019374801A1] A flame front in a gas pipeline is extinguished by introducing an extinguishing agent at an overpressure at an extinguishing zone of the pipeline. Using an overpressure provides a better and finer atomization of the extinguishing agent, and permits a greater amount of the extinguishing agent to be provided in the extinguishing zone per unit time. In addition, a sealing fluid is introduced at sealing zone of the pipeline. Gas flowing through the pipeline must flow through the sealing fluid in the sealing zone. Preferably, movement of a flame front from one side of the sealing zone to the other side of the sealing zone is prevented or reduced by the sealing fluid.
Abstract (de)
Die Erfindung betrifft ein Verfahren zum Löschen einer Flammenfront in einer Gasleitung 2, wobei das Verfahren die Schritte aufweist:(a) Einleiten eines Löschmittels unter einem Überdruck in einen Löschbereich L der Gasleitung 2, und zudem(b) Einleiten einer Sperrflüssigkeit in einen Sperrbereich S der Gasleitung 2, sodass die Sperrflüssigkeit derart in dem Sperrbereich S verbleibt, dass ein durch die Gasleitung 2 strömendes Gas in dem Sperrbereich S durch die Sperrflüssigkeit strömen muss.
