  • Steam generator sludge lancing method
    Patent number: 4276856
    Abstract: A method for removing sludge that may be deposited on a tubesheet of a steam generator comprises placement of fluid headers 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 pulsating fluid jet perpendicular to a 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 tubesheet where the sludge is entrained in and carried away by the circumferential fluid stream.
