摘要
A system for removing sludge that may be deposited on a tube sheet of a steam generator. Headers are arranged at the elevation of the sludge to be removed establishing a circumferential fluid stream at that elevation. A fluid lance is moved along the line between the headers emitting a fluid jet perpendicular to the line of movement of the fluid lance at an elevation substantially corresponding to the level of sludge deposits. The fluid jet forces the sludge to the periphery of the tube sheet where the sludge is entrained in and carried away by the circumferential fluid stream.
