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.
About cleaning
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.
Lower and more stable differential pressure. 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.
Increased lifetime of heat exchangers. 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.

ENA Energi, Enköping Sweden
In this boiler at ENA Energi, the HISS system is used for being able to operate the steam soot blowers in the superheater more often when combusting more difficult fuel (waste wood)
Kraftvärmeverket Eskilstuna, Eskilstuna Sweden
HISS was installed for being able to soot blowing more often in the superheaters, thereby keeping those parts clean, without consuming more soot blowing steam.
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.

A case study and results of an infrasound installation at Finspångs tekniska verk. Before installing the infrasound generator at Finspångs tekniska verk, there were two audible sonic horns installed on the smoke tube boiler.
