About Biomass boilers
Biofuels offer challenges in order to reach high efficiency and availability. Biofuel normally tends to create gas-side fouling in all parts of the boiler.

Benefits of our soot cleaning systems for Biomass boilers
Reduced steam consumption for steam sootblowing. Saved sootblower steam is used for increasing heat or electricity production.
Lower fuel consumption. Cleaner tubes mean increased heat transfer and efficiency.
ความดันแตกต่างที่ต่ำลงและเสถียรยิ่งขึ้น. Infrasound cleaning reaches areas that are not accessible to conventional soot cleaning systems. This means higher availability of the boiler and lower load on ID/FD fans.
Fewer and shorter outages for manual cleaning. With improved cleaning effect you can obtain higher availability and fewer man-hours spent.
เพิ่มอายุการใช้งานของเครื่องแลกเปลี่ยนความร้อน. By reducing or eliminating steam sootblowing or shot cleaning, the lifetime of heat exchangers is prolonged. Infrasound cleaning is a non-abrasive cleaning method that does not wear on heat exchange surfaces or catalyst elements and does not contribute to corrosion or erosion. Using our optimized steam sootblowing also reduces wear since steam is supplied only half the time.

At Sandviken Energi, The smoke tube boiler produces the basis of Storvik’s district heating. There was previously no soot cleaning equipment installed on the boiler.
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.
