Patent AT516424B1: Shake it up !!!

At the occasion of the recent publication on our patent AT516424B1 (link EPO/Espacenet, link Austrian Patent Office, link Google patents), here is a brief overview of the invention.

 

Driving precisely the flame turbulence by controlling the thermoacoustics can have positive effects near the lean-blow out limit, and at points where the combustion stability is impaired.

One key technology in this process is CBOne's siren, a powerful and precise flow modulator able to autotune and maintain the desired flame pulsation, even with operation transients. Read more about the siren with our latest ASME Turbo Expo publication, to be released in the early summer 2020.

At this point, we would like to thank our research contributors, the AWS and the FFG, as well as our dear Clients who helped us through their queries to improve this technology with time.
