Sonic Cleaner

The Infrafone sonic cleaning device utilizes low frequency sound energy as a medium for the cleaning of air preheaters, economizers, refinery CO boilers and other applications.

Infrasonic (below the range of human hearing) sound waves are reflective, omni-directional and powerful. This low frequency sound energy creates fluctuations in the static pressure of the gas flow, which in turn causes any particles suspended in the gas flow and the gas flow itself to oscillate. The resulting action helps to loosen and remove ash deposits from the surfaces in the gas flow and acts to keep ash particles suspended in the gas flow, thereby inhibiting the formation of new ash deposits.

The omni-directional properties of the infrasonic energy enable the cleaning effect to reach areas that may be sensitive to erosion from steam or air sootblowing.
