Abstract:
Apparatus and methods are provided for cleaning a surface within a vessel. An elongate combustion conduit extends from an upstream end to a downstream end associated with an aperture in a wall of the vessel and positioned to direct a shockwave toward the surface. A resilient member resiliently restrains the combustion conduit against recoil forces.
