Abstract (en)
An apparatus (22) is provided for cleaning a surface within a vessel (20). A vessel wall separates a vessel exterior from a vessel interior and has a wall aperture. The apparatus comprises an elongate conduit (26) having an upstream first end (28) and a downstream second end (30). The conduit (26) is positioned to direct a shock wave from the second end (30) into the vessel interior. A source (32,34) of fuel and oxidizer is coupled to the conduit (26) to deliver the fuel and oxidizer to the conduit (26). An initiator is positioned to initiate a combustion of the fuel and oxidizer. The conduit (26) comprises a first portion (50) and a second portion (52) downstream of the first portion (50). The second portion (52) is extensible and contractible relative to the first portion (50) to selectively position the second end (30) at a desired location within the vessel (20). The conduit downstream end (30) comprises a centerbody (72) positioned to direct the shock wave essentially axisymmetrically.
