Infrasound acoustic cleaning

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.

Optimization of infrasound power

Our technology is based on taking advantage of the properties of infrasound, since our system operates within a frequency range from 15 Hz to 30 Hz.

Sound can be divided into infrasound, audible sound and ultrasound. The sound properties differ substantially depending on the frequency range.

Infrasound is suitable for soot cleaning applications for several reasons. It reaches areas far away from the acoustic source, unlike conventional soot cleaning methods or even audible sound cleaning methods. It spreads in all directions with the same intensity, and the energy loss of infrasound across the space is rather low. In short, this means that even boilers with big cross-sectional areas, boilers with compact tube bundles or even finned tube bundles are suitable applications for our technology. The energy of infrasound is far reaching and will affect even the innermost areas.

Besides, space constraints for the installation of the system are seldom an obstacle due to the flexibility that the infrasound properties give us.

The infrasound energy, when properly engineered and applied, causes oscillations within the flue gas flow. The turbulence created by the oscillations prevents accumulation of soot deposits on heat exchange surfaces.

Our Knowledge

Generating infrasound is not enough to obtain the desired cleaning effect. You need to know how to take advantage of it. Our continuing development has ultimately led to unique acoustic modelling software which simulates the behavior of infrasound waves in the customer’s application and calculates the optimal installation location and parameter settings of each unit. Therefore every Infra- sound Soot Cleaner is tailor made for each specific application.

 

Our Quality

We believe that our customers define quality. Customers buy on perceived value, measuring benefits against costs and selecting a product that provides superior value in a cost effective way. That is why, to us, quality means to delivering products and services that address our customer needs and live up to their expectations regarding high return on investment, functionality, reliability, in-time delivery, environmental friendliness and excellent service.

Our Team

Being experts in infrasound soot cleaning is not enough. Understanding our customer’s business and challenges is at least as important. Our team has a deep knowledge in infrasound cleaning and a wide experience in helping energy producers to improve boiler efficiency, availability and lifetime. We work together with our customers, every step of the way, to ensure that the process moves smoothly forward.
