Abstract (en)
[origin: WO9849671A1] A method and apparatus for removing contamination or corrosion, as defined, in a chamber or pipe is described. The apparatus comprises a horn and transducer assembly; said horn having two ends, a first end of which is in contact with an external surface of the chamber or pipe; an acoustic transducer in contact with the other end of the horn; and means for energising the acoustic transducer, whereby in use acoustic energy from the transducer is guided through the horn to the surface of the chamber or pipe and thereby into the liquid contained therein.
