The customers of Infrafone have with the help of the green and clean infrasound soot cleaning technology experienced improved profitability gains of their boilers. This has been achieved thru improved efficiency of soot cleaning in economizers, air-preheaters, catalysts (SCR’s), electrostatic precipitators (ESP’s) etc with a general payback time of about 6 to 24 months. Traditional soot cleaning technologies such as steam soot blowing, shot cleaning and manual cleaning have been heavily reduced or even eliminated in certain applications.
Our range of products is the result of our unique knowledge and our customer focus. We calculate the optimal size of the Sonic Soot Cleaner for each customer’s particular need and we design each Sonic Soot Cleaner according to the spatial possibilities of each installation.

The patented HISS technology, originally developed by the company SootTech, transforms your steam sootblowing system into an effective tool that handles clogging and increases the efficiency of your power and recovery boilers.
Why not do like Munksjö Aspa Bruk, Billerud Skärblacka, Smurfit Kappa Krafliner Piteå, Eskilstuna Energi and Ena Energi?
• Halve your steam consumption
• Increase you production of electricity
• Double your sootblowing power
• Use cheaper fuel
Increased sootblowing frequency
More than 90% of the cleaning by a sootblower takes place during the sootblower’s initial stroke.
When the sootblower is retracted, 50% of the steam is used unnecessarily at the same time as the soft ash is sintered into concrete-like deposits
With HISS (High Impact Soot System), several sootblowers are operated in parallel with or without return steam, i.e. more sootblowing, less steam, more easily removed ash.
Examples of increased power and steam savings of 68% with HISS.
Increased power and steam savings
With rising electricity prices, it is important for the recovery boiler to generate as much electricity as possible.
The efficiency of the economizer surfaces directly affects the volume of high-quality steam energy produced at the same time as sootblowing is often shifted away from economizers due to clogging earlier in the flue gas direction.
With SootTech’s HISS technology, it is easy to increase heat absorption in MW levels by cleaning the economizer surfaces more effectively without any increase in soot steam consumption or volume of flue gas.
In HISS electricity mode, it is a simple matter to redistribute sootblowing and directly increase electricity production in megawatts when electricity prices are high.
Faulty runs and periods of very large carry-over are not unusual. These “periods” often result in permanent deposits that cannot be removed by means of sootblowing.
The best way of dealing with carry-over is to sootblow much more frequently so that the ash does not have time to sinter.
With SootTech‘s CarryOverMode, sootblowing can be focused with the press of a button to the front section of the boiler and performed e.g. 3-5 times more frequently than normal.
SootTech‘s CarryOverMode, together with HISS technology, means that you are less likely to suffer from operating errirs since you then have the tools to effectively deal with the consequences.

Some fouling issues are related to poorly distributed flue gas flow. An uneven distribution may also result in increased gas velocity in some parts, which can lead to erosion and rapid wear of heat transfer surfaces, SCR elements etc. Heat transfer in heat exchangers is also depending on flow distribution. In ESPs the distribution of the flue gas is a challenge demanding accurate design of inlet duct, guide vanes and distribution screens.
Infrafone offers CFD simulations to assist in choosing proper design of flue gas ducts, ESP inlets and other applications.
Noise and vibrations
Beyond soot cleaning solutions Infrafone offers systems for reduction of noise and vibrations. The technology is best suited for low frequency noise and vibrations in the 15-50 Hz range.
To reduce low frequency vibrations we use our patented vibration damper solution. The vibrations dampers are used together with our infrasound generators to minimize vibrations but can also be used on other vibrating equipment.
Low frequency noise, e.g. noise originating from a fan or engine, is reduced by our sound reflectors designed for noise reduction in a certain frequency span. A sound reflector installation is preceded by sound measurements, e.g. in a duct, to decide proper installation location and design of the sound reflector. Infrafone has successfully installed sound reflectors both on combustion plants and ships. After installation noise and vibration measurements are performed to confirm the results.
