Acoustic Cleaning In Power Stations, Power Plants: Super Heaters
Ash and particulate build up on super heaters causes a reduction in boiler efficiency. Primasonics acoustic cleaners use sound to remove this build up, as sound is used it removes particles from all around the heat exchange tubes rather than simply creating a path for air flow.
The use of acoustic cleaners therefore leads to low differential pressures across super heaters and a larger temperature differential when compared with traditional cleaning methods.
As the rapid pressure fluctuations of the sound is used to remove particles rather than a blast of air or steam problems of boiler tube erosion are removed.
Primasonics® offers a range of acoustic cleaners manufactured from Inconel for use in super heater sections.
Very little modification of super heaters is required to fit an acoustic cleaner as man ways and access points can be used to mount the acoustic cleaner so that water jacket walls and refractory lining are not affected.
