Abstract (en)
The method involves injecting a cleaning fluid through openings into an annular compressor channel (25) of an axial compressor (18) by an injecting device, where the openings are arranged in an outer channel wall (42) of the compressor channel or in compressor vanes (27) i.e. guide vanes. A penetration depth of the injected cleaning fluid is varied. A supply pressure of the cleaning fluid is varied and pulsated. The injecting device is provided with components that are opposite to a main flow direction in the compressor.
Abstract (de)
Die Erfindung betrifft ein Verfahren zum Waschen eines axial durchströmbaren Verdichters (18), bei dem in einen Verdichterkanal (25) eine Reinigungsflüssigkeit durch in einer Kanalwand (42) des Verdichterkanals (25) oder in den Verdichterschaufeln (27) angeordnete Öffnungen eingespritzt werden. Um unterschiedliche Bereiche des Verdichterkanals (25) von Effizienz mindernden Ablagerungen zu befreien, ist vorgesehen, dass die Eindringtiefe der eingespritzten Reinigungsflüssigkeit variiert.
