Use of Low-Frequency Sonic Devices for Control of Deposits in Boilers and Precipitators
MetadataShow full item record
Acousticlean Sonic Sootblowers, or 'horns' are low frequency, high energy acoustical devices which offer a low-cost approach to cleaning many areas of the boiler and its associated equipment. The horns are presently in use and/or are being evaluated at more than 50 sites in the U.S., and at many more in Europe, where the technology originated. This paper describes five industrial applications of the horns to solve operating problems in varied industries. The applications discussed include utilization in pulp mill hog fuel boilers to substantially reduce steam lancing requirements; use in recovery boiler precipitators to reduce salt cake buildups; maintenance of clean economizer sections in oil field steam generators; waste fuel boilers; and precipitator dust minimization in smelting operations. A comparison of acoustical energy versus steam sootblowing costs is also included.
