General info
Payback within 6-24 months after implementation
Our Infrafone cleaners (low-frequency acoustic cleaning) improves the profitability of boilers. This has been achieved thru more efficient soot cleaning in e.g. economizers, air-preheaters and catalysts (SCR’s), with a general payback time of about 6 to 24 months. Traditional soot cleaning technologies such as steam sootblowing, shot cleaning, sonic cleaning (high frequency), and manual cleaning are generally heavily reduced or eliminated in these applications.
Our range of products is the result of our unique knowledge and our customer focus. We calculate the optimal size and design of the acoustic cleaner for each customer’s particular need and the spatial possibilities of each installation.

Infrasound cleaning case studies
Händelöverket P15, Norrköping Sweden
During 2005 the availability of the boiler at Händelöverket was just 7600 hours due to required stops for maintenance. Apart from the two regular stops per year, the boiler had to be shut down two times per year for manual cleaning of the economizer.
Moelven Sawmill, Edane Sweden
A case study and results from our infrasound cleaning installation on a Biomass boiler at Moelven Sawmill. At Moelven Sawmill a Compressed air sootblowing is installed but is relatively weak due to nozzles being installed on the turning chamber between the two tube passes, far from the inlet of the first tube pass where most of the deposits are found.
Skogsbacka Kraftvärmeverk, Lycksele Sweden
Skogsbacka Kraftvärmeverk was using steam soot blowing in the economizer once every 24 hours prior to the installation of the infrasound generator. The performance of the existing soot blowers was not satisfying and the cost for maintenance of the soot blowing system was considered too high
Perstorp Fjärrvärme P6, Perstorp Sweden
At Perstorp Fjärrvärme, Steam soot blowing was previously used six times per day in the economizer and there were also two unplanned stops per year for manual cleaning. The unplanned stops are costly and are preceded by an increased differential pressure which increases the flue gas velocity, leading to increased erosion and uneven flue gas distribution.
