Acoustic Cleaning: A Step to Constant Boiler Availability
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; [...]
