  • —Literature Available Infrasonik AB of Finspong, Sweden, is offering literature on a new boiler cleaning technique that offers savings for vessel owners.

    The eight-page color brochure, entitled "Infrafone—the new approach to boiler cleaning," explains that the technique is based on maintaining a constant sound pressure in an enclosed space by generating infrasound— sound waves with a low frequency (approximately 20 Hz) and a long wavelength (17-30 m).

    The Infrafone equipment consists of a sound generator comprising an air feeder unit connected to a quarterwave resonator in the form of a resonance tube. In simple terms, the equipment works like an organ pipe, and its only source of power is an air blower.

    The company says that the technique is simple, and despite the fact that it is young it has already produced convincing proof of being vastly superior to conventional methods of sootblowing. Advantages listed are: appreciably more efficient cleaning; high efficiency— lower operating costs; wear is eliminated— maintenance is minimized; the pay-off time is less than one year; installation is simple, involving a boiler stoppage of no more than one day; and since infrasound is non-directional, the equipment can be located virtually anywhere.

    The technique is said to perform excellently on boilers fired with most fuels—coal, oil, wood chips, bark, peat, municipal refuse, magnesium oxide and black liquor.

    The publication is well illustrated with drawings, charts and color photos.
