Prior to the installation of Infrafone’s  Sonic Soot Cleaner, Lycksele Energi used steam soot blowers to keep the boiler clean. Since the commissioning of the cleaning system, Lycksele Energi has not operated the steam soot blowers again. The tubes are very clean in the economizer and a stable outlet temperature is maintained. A positive side effect is that the sonic cleaner keeps the electrostatic precipitator clean as well.

Some of the benefits that the Sonic Soot Cleaning System has brought to the customer are:

  • Reduced steam consumption due to eliminated need of soot blowing in the economizer.
  • Reduced wear on economizer tubes.
  • Better performance of the electrostatic precipitator.
