Cleaner boilers. Lower operating costs.
SootMotion™ cleans your biomass boiler continuously with infrasound – without wear. Higher efficiency, less manual cleaning and the option to burn cheaper, more ash-rich fuel.
What you gain
Higher efficiency
Clean surfaces mean better heat absorption and lower fuel consumption.
Cheaper fuel
Move from chips (~0.5% ash) to bark (~3%) or logging residues (~2%).
Less manual cleaning
Continuous sootcleaning cuts unplanned stops and shortens planned ones.
Less wear
No mechanical wear on tubes and plate surfaces – longer lifetime.
Scalable and reliable
Adapted to boiler size and fuel type, with remote monitoring and support.

How infrasound sootcleaning works
Low-frequency sound instead of steam, compressed air or mechanical sootblowers – powerful, gentle and cost-efficient.
Powerful turbulence
Sound waves at 14–25 Hz oscillate the flue gases and break the bond between soot, ash and metal surfaces.
Continuous operation
Runs on your compressed air (3–8 bar), 0.5–2 seconds every 3–5 minutes during operation. Less air than air sootblowing.
No wear
No physical contact with the metal surfaces – zero erosion on tubes and turning plates, longer boiler lifetime.
Clean all the way – from furnace to flue gas cleaning
A single unit is mounted at the top of the fire-tube boiler (~350 °C). The sound travels both upstream to the furnace and downstream through the entire flue gas path.
Furnace
More combustion turbulence and easier ash discharge.
Empty draft (cooled)
Keeps the draft free from soot build-up.
Fire-tube boiler
Mounting point – where the effect on heat transfer is greatest.
Multicyclone & duct
Counteracts deposits on the way to the ESP.
ESP & flue gas fan
The effect reaches the fan. Bag filters are not negatively affected.
Result: cleaner surfaces through the entire flue gas path – better combustion and heat transfer, higher availability and less maintenance on the multicyclone, ducts and ESP.
From analysis to operation
We take end-to-end responsibility – from inspection to commissioning and ongoing optimisation.
Needs analysis
We map the deposit pattern in your boiler.
Installation
1–2 days with your own welders and electricians, commissioned while running.
Control
Connected to the boiler control system and tuned for every operating point.
Follow-up
Regular inspections and parameter adjustments.
