Boiler Acoustic Sootblowers - Boiler Services

Overview BTADrayton is the only sootblower manufacturer to embrace both media (steam/air), and non-media (acoustic) sootblowers. In addition to supplying spare parts for Diamond Power®, Copes Vulcan® and Bergemann® sootblowers, BTADrayton has developed our own design for Sonic Sootblowers.

BTADrayton Sonic Horns can be used in a variety of applications for the purposes of dislodging material build-up. The most common use for Sonic Horns or Sootblowers is in the back pass of the boiler, where the flue gas temperature is low enough to produce a dry fryable deposit.

Sonic Horns/Sonic Sootblowers are air operated devices that produce low frequency, high energy sound waves. The sound waves are produced when compressed air enters the sound generator and forces the only moving part, a titanium diaphragm, to flex. The flexing action of the diaphragm generates sound waves that are amplified by the sonic horns bell. The resulting sound waves cause particulate deposits to resonate and dislodge from the surfaces to which they have bonded. Once dislodged, the deposits are then removed by gravity and/or gas flow.

Sonic Horns/Sonic Sootblowers have been successfully installed on boilers burning a variety of fuels. Such as coal, garbage, oil, and wood. The use of Sonic Horns on boiler applications offer many advantages when used with conventional style Sootblowers. Benefits Improved Heat Transfer Efficiency - Sonic Sootblowers in boiler applications, are typically operated for ten seconds every ten minutes. The aggressive sounding of the acoustic cleaners keep the soot deposits from building up on the heat transfer surfaces. This allows for heat transfer efficiency to be maintained at all times. Steam Sootblowers alone are cycled much less frequently (every four to eight hours) allowing heat transfer surfaces to build up deposits before cleaning. This results in periods of poor heat transfer efficiency. Improved Boiler Emissions - The repeated sounding of Sonic Sootblowers on. ten minute intervals also benefits the performance of the pollution control equipment. The acoustic cleaners are entraining a nominal amount of soot deposits every time they are sounded allowing the pollution control equipment (Baghouse, Electrostatic Precipitator, Mechanical Collector) to more efficiently collect the entrained soot, resulting in lower emissions. This benefit is more pronounced on boilers not equipped with sophisticated pollution control equipment. Extended Life of Heat Transfer Surfaces - The low frequency high energy sound waves emitted from BTADrayton Sonic Sootblowers are not damaging to the boiler internals. The sound waves are an efficient means of cleaning the heat transfer surfaces without causing tube erosion or thinning. Experience also shows that the sound waves have no adverse effect on refractory or welds. Maintenance Cost Savings - BTADrayton Sonic Soothlowers have only one moving part, a titanium diaphragm. The diaphragm is guaranteed for one year and has a life expectancy of over five years. The low maintenance required for the acoustic cleaners offers potential money savings when used to augment the operation of conventional Steam Sootblowers. Other Applications
