Heat Management’s Infrasound cleaners has been exceptionally popular historically in Sweden, which is its country of origin. The acoustic cleaner has satisfied its users for years, but in the last few years the demand outside of Sweden has grown exponentially. This has led to a record year for Heat Management, having a lot of Infrasound cleaners to install and commission all over the world, especially in Asia. New exciting partnership in Southeast Asia Our sales manager in Thailand, Thierry Magne, has signed a partnership with Eco Plant Services (EPS) who has been providing our acoustic cleaning solution to the market. Heat Management has received multiple orders in Thailand with the help of our new partner. With the continued collaboration with EPS and Heat Management, anything is possible, which makes the market in Thailand look very promising. The end-users have been everything from cement plants, coal fired boilers to smoke tube boilers. Together we’re building success stories together with our [...]
Plugging and reduced heat transfer When being exposed to fouling, heat-transferring surfaces lose effectiveness over time due to scaling and buildup. This keeps power boilers from reaching their full potential. To unlock the potential of the boiler, it requires cleaning. One way that most plants around the world do this is by manually cleaning the desired area during a designated stoppage. This, however, poses a major loss in energy production. In this section we present three plants that had major issues with this before implementing acoustic cleaning. Click on their name to download an in-depth case study: Mälarenergi, Kraftvärmet Block 6: A Swedish waste-to-energy plant that had to stop their boiler operation, to sandblast the economizer every 3-6 months. Sandviksverket, Växjö: A Swedish CFB boiler, fuelled by biomass, that reduced their sootblowing steam consumption by 50% in the air preheater and economizer. The acoustic cleaner also fully eliminated the need to sootblow in the catalyst. EEW Delfzijl, Holland; [...]
Carbon capture project with cement producer Norcem will significantly lower carbon footprint using infrasound soot-cleaning
The Brevik Carbon Capture and Storage project reduce CO2 emissions by 400,000 tonnes a year, paving the way for a net-zero carbon footprint for the cement lifecycle. Heat Management joins forces with Aker Carbon Capture by supplying powerful infrasound cleaning technology to keep the waste heat recovery boilers clean.
The first installation of an Infrafone Sonic Soot Cleaner with the purpose to keep an industrial boiler clean from soot was carried out in 1978. The boiler was an MgO boiler in a paper mill at Stora Enso in Hyltebruk, Sweden. The success of that installation taught us about the power of infrasound. The experience that we have obtained over the years has taught us how to create value with infrasound. The properties of sound differ substantially depending on the frequency range. Sound can be divided into infrasound, audible sound, and ultrasound. Infrafone harnesses the power of infrasound, which is sound with frequencies below 30 Hz. Infrasound waves have many properties that make them suitable for soot cleaning applications: Infrasound waves have a long wavelength. The acoustic power can reach areas far away from the acoustic source, unlike conventional soot cleaning methods. Infrasound waves are Omni-directional. This means that they spread in all directions with the same intensity, which implies [...]
