Abstract:
A sludge lance for a tube and shell steam generator that has a central divider plate that extends substantially the length of a central tube lane substantially bisecting a hand hole through which the tube lane can be accessed. The sludge lance has a nozzle with a spring biased, reciprocally movable plunger that extends against the divider plate and is locked in position by a stream of high pressure cleaning fluid that traverses the nozzle and exits through jets to clean sludge from between the tubes. An alignment tool with a swing arm indexes the jets to assure they are properly aligned with the tube rows and spaced from the divider plate.

Claim (Index 1):
An alignment tool assembly for a steam generator sludge lance to align the sludge lance with structures within the steam generator, the steam generator having a shell enclosing a tube sheet and a plurality of substantially uniformly diametrically sized tubes extending from the tube sheet with the tubes disposed in a substantially regular pattern having substantially uniform narrow gaps between adjacent tubes, the regular pattern forming a generally central lane with the shell having at least one access opening in-line with the central lane, the alignment tool assembly comprising:\n a mounting assembly structured to support a drive assembly and a rail; and an alignment tool structured to move along the rail and determine a linear distance between a sludge lance nozzle assembly on the rail and one the plurality of tubes closest to a pointer on the alignment tool.
