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
Fortum Naantali, Naantali Finland
A case study and results from our infrasound cleaning installation on a coal-fired boiler at Fortum Naantali. Fortum Naantali power plant uses coal as the main fuel. Heavy fuel oil is used for start-ups and as support fuel. Refinery gas is also used. The two boilers each have two air preheaters, each with an Infrasound generator installed below the rotor on the flue gas side.
Block 7 and Block 8, Rybnik Poland
A case study and results from our infrasound cleaning installation on a coal fired boiler at Block 7 and Block 8 Rybnik. At Block 7 and Block 8 Rybnik, the infrasound generators were installed when retrofitting the boilers with SCRs.
Ryaverket AP1 – AP2, Borås Sweden
A case study and results from our infrasound cleaning installation on a WtE boiler at Ryaverket. At Ryaverket, Steam soot blowing was previously used three times per day in the economizers.
Tidaholms energi, Tidaholm Sweden
At Tidaholms Energi, Compressed air soot blowing is installed but relatively ineffective because of the valves being mounted on the turning chamber, far away from the problem area. This results in the air pressure not reaching the problem area.
