Infrafone Sonic Soot Cleaning can be used to optimize the cleaning of evaporators in different types of boilers, using different types of fuels. Infrafone Sonic Cleaning for evaporators is most suitable where the soot deposits are dry. By applying Infrafone Sonic Soot Cleaning on evaporators the use of conventional cleaning systems can be reduced. Conventional cleaning methods are often inefficient when it comes to reaching all parts of the evaporator, especially for evaporators with small tube pitch. The use of highly reflective, long wavelength infrasound that can travel long distances and is not shielded by obstacles (tubes) means that all parts of the evaporator bundles are reached.

The reduced use of conventional cleaning systems such as steam soot cleaning and shot cleaning that are highly abrasive and require extensive maintenance will result in:

  • Reduced steam consumption for steam soot cleaning. Increase energy production or reduce fuel costs while production is maintained.
  • Increased lifetime of tubes and elements. Non-abrasive sonic cleaning increases the lifetime of tubes and elements by reducing the need for conventional cleaning systems. Infrafone Sonic Soot Cleaning does not contribute to corrosion or erosion of tubes and elements.
  • Lower and more stable differential pressure. Infrafone Sonic Soot Cleaning system reaches areas that are not accessible to conventional soot cleaning systems. This leads to reduced soot accumulation and reduced power consumption of ID/FD fans.
  • Fewer outages for manual cleaning. Increased availability and energy production.
