Abstract
An apparatus for cleaning a surface within a vessel has an elongate combustion conduit extending from an upstream end to a downstream end. The downstream end is associated with an aperture in the wall of the vessel and is positioned to direct a shockwave toward the surface. At least one hanger supports the combustion conduit at at least one location along a length of the combustion conduit.
Claims19
An apparatus for cleaning a surface within a vessel, the apparatus comprising:
- an elongate combustion conduit extending from an upstream end to a downstream end associated with an aperture in a wall of the vessel and positioned to direct a shock wave toward said surface;
- and
- means for movably supporting the combustion conduit at one or more locations along a length of the combustion conduit, the means comurising one or more hangers wherein:
- the one or more hangers engage first portions of the combustion conduit;
- the one or more hangers couple the conduit to a support structure, the structure being separate from the furnace wall, and
- a second portion of the combustion conduit downstream of the first is held relative to the vessel so as to vertically move with the vessel due to thermal expansion of the vessel, the one or more hangers compliantly accommodating such vertical movement relative to said support structure.

- and
- one or more hangers supporting the combustion conduit at one or more locations along a length of the combustion conduit, wherein:
- the one or more hangers engage first portions of the combustion conduit;
- the one or more hangers couple the conduit to a support structure, the structure being separate from the furnace wall, and
- a second portion of the combustion conduit downstream of the first is held relative to the vessel so as to vertically move with the vessel due to thermal exnansion of the vessel, the one or more hangers compliantly accommodating such vertical movement relative to said support structure.
A combination of a vessel and an apparatus for cleaning a surface within the vessel, wherein:
- the vessel has a first external tube bundle and a second external tube bundle;
- and
- the apparatus comprises:
- an elongate combustion conduit extending from an upstream end to a downstream end associated with an aperture in a wall of the vessel and positioned to direct a shock wave toward said surface, the combustion conduit passing above the first external tube bundle and below the second external tube bundle;
- and
- means for movably suspending the combustion conduit at one or more locations along a length of the combustion conduit.
