ABSTRACT:
The present invention relates to a method and apparatus for cleaning and removing the buildup of products of corrosion, oxidation, sedimentation and comparable chemical reactions from various portions of a fire tube boiler. Specific areas to be cleaned are the surfaces of the fire tubes, crevices, and junctions inside the boiler. Also cleaned is the location where the fire tube boiler comes into contact with the tube sheets, boiler shell and fire tubes. One or a plurality of ultrasonic transducers are placed inside the boiler and activated to transmit ultrasonic energy at a sufficient amplitude and frequency to dislodge deposits, sedimentation and sludge from the interior surfaces of the boiler.
