ABSTRACT:
A pivotal housing member has an end pivotally coupled to an end of a base housing member for movement between a retracted or folded position and an extended position. The pivotal housing member has a pulsed deflagration or detonation device located therein for producing pulsed deflagration or detonation pressure waves for cleaning purposes. When the pivotal member is in its folded position, the two housing members may be moved through the opening formed through the wall of a boiler, etc. for cleaning the interior surface of the wall with the pulsed pressure waves. In order to increase the wall area cleaned from a given wall opening, the two housing members may be rotated about an axis of the base housing member and the pivotal housing member pivoted to different extended positions from its folded position.
