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.

Södra Skog, Långasjö, Sweden

A case study and report from our Infrasound cleaning installation at Södra Skog, Långasjö, Sweden. The goal with the Infrasound Cleaner projects at Södra Skog was to reduce the need for manual cleaning and auxiliary firing due to the reduced number of stops.

SYSAV Kraftvärmeverk, Malmö Sweden

At SYSAV Kraftvärmeverk, Continuous shot cleaning was used for keeping the economizer clean as well as the convection area. The power plant had to shut down the boilers for manual cleaning of the economizer and the convection area every 10- 12 weeks.

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.
