Since the commissioning of the sonic cleaner APX2000 in September 2006 the primary superheater, economizer and air preheater are cleaner. The deposits in the duct after the economizer are now gone.

The boiler is generally considerably cleaner and no big soot build-ups occur. The boiler efficiency is now 0.5 to 1 % higher than before the Infrafone installation.

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

  • Increased boiler efficiency
  • Less wear on tube bundles
  • Annual stop is faster and easier to perform
