Abstract
A method for removing accumulated ash from the heat exchangers within a steam generator includes introducing a series of high-energy shocks to the tubing panels of the heat exchangers. Explosive cords are attached to the tubing panels at preselected, spaced-apart locations and separately detonated at preselected intervals to establish a vibratory pattern in the tubing panels and thereby separate the ash from the tubing panels.
