Acoustic Expert from Primetals Technologies monitors bag filters in dedusting plant at voestalpine

Print

At the end of January, a new acoustic monitoring system was brought into operation in the secondary dedusting plant 3.1. at voestalpine Stahl GmbH in Linz, Austria. The “Acoustic Expert”, developed by Primetals Technologies, measures the sound spectrum emitted during the cleaning of the bag filter via the Pulse-Jet System. This enables deviations from the nominal state to be detected, and condition-based maintenance activities to be initiated. The Acoustic Expert system implemented at voestalpine was installed in one day without any plant stoppages, optimized in just two days, and brought into operation two months before the scheduled date.
