Coal fired boiler

The boiler island in a power plant constitutes the highest capital expenditure asset and the fuel is generally the single highest operational expenditure of the plant. Often, not enough attention is given to continuously improve the energy transformation efficiency; from raw fuel to the refined end-products heat and power. The potential for sustainable and profitable growth is directly connected to how well the plant handles increasing demands, from both consumers and legislators (BREF), on reduced emissions.

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.

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

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
