Coal fired boilers

Heavily reduced or eliminated steam soot blowing, increased availability, reduced maintenance costs and increased lifetime of heat exchangers and catalysts.

Using coal as fuel in order to create energy in the form of electricity and/or heat is very common in the world. The coal comes in many different qualities, and often generate problems with ash fouling. The stricter limits for emissions, also create new challenges for the boilers, such as difficulties with build ups in heat exchangers, SCR and APH.

Heat Management has a long history of supplying fouling management in these systems.

Typical applications for the Infrasound Cleaning in coal fired boilers are Economizers, Air Preheaters (Ljungstrom, Rothemuhle, tubular) and Catalysts.

Our HISS™ system for optimizing steam soot blowing is used for saving soot blowing steam or increasing cleaning effect, mainly in warmer areas such as superheaters.

Some of the benefits that our systems can give the customer:

  • Reduced steam consumption for steam soot cleaning. Increased production or reduced fuel costs while production is maintained.
  • Lower and more stable differential pressure. Infrasound Cleaning reaches areas that are not accessible to conventional soot cleaning systems.
  • Fewer stops for manual cleaning. Increased availability and energy production.
  • Increased lifetime of heat exchangers. Non-abrasive sonic cleaning increases the lifetime of heat exchangers by reducing the need for conventional cleaning systems. Infrasound Cleaning does not contribute to corrosion or erosion of heat exchangers. Using our HISS optimization of steam soot blowing also reduces wear since steam is supplied only half the time
