  • Method for cleaning a tube plate of a heat exchanger from inside the bundle of the heat exchanger
    Patent number: 5833767
    Abstract: At least two pivoting jets (55a, 55b, 55c) of cleaning liquid, each directed between two successive lines of tubes substantially perpendicular to the rows of tubes, are sent, in succession, from locations situated inside the bundle of the steam generator, into a space between two successive rows of tubes so as to sweep the tube plate between a central part vertically in line with the space between the two rows of tubes and two outer parts situated at the periphery of the bundle and along the length of the space between the rows of tubes. The flow rate of cleaning liquid is at least equal to 20 1/min, per jet. The invention applies in particular to the cleaning of the tube plate of a steam generator of a pressurized-water nuclear reactor.
