Abstract: A shockwave cleaning apparatus cleans one or more surfaces within a vessel. A sensor senses one or more thermodynamic properties associated with the vessel. A control system is coupled to an initiator and a fuel/oxidizer source to control the firing of the apparatus responsive to input from the sensor.

Abstract: An inspection camera may be used in conjunction with a shockwave cleaning apparatus. The camera has a head held in an operative position within a vessel interior. A light source has at least a light emitting element carried by the head. At least an incident lens of the camera is carried by the head so as to capture light from the source as returned by a surface within the vessel interior.

Abstract: An apparatus for cleaning a surface within a vessel is supported at least partially above a support surface. The apparatus had an elongate combustion conduit extending from an upstream end to a downstream end The downstream end is associated with an aperture in a wall of the vessel and positioned to direct a shock wave toward the surface. A guide member is on the support surface. A number of support assemblies support the combustion conduit at a number of locations along a length of the combustion conduit and engage the at least one guide member.

Abstract: Pressure probe methods and apparatus are disclosed. An exemplary probe includes a body having an exterior surface with a forwardly-convergent nose. A passageway extends between a first port in the body and a pressure sensor. A support member holds the body in an operative position. A cooling fluid circuit extends at least partially through the support member and body. The pressure probe may be used in conjunction with a detonative cleaning apparatus.

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.

Abstract: A detonative cleaning apparatus may be configured to accommodate a desired embodiment by securing a number of conduit segments end-to-end in an appropriate configuration.
