Einfluss von Ultraschall auf die Agglomeration der Flugasche in Rauchgasen

On the basis of various measurements a simulation model is presented. It shows the influence of ultrasound on the agglomeration of fly-ash in exhaust gases. An appropriate sound source placed before the electrofilter improves the separation efficiency. The improvement of filter separation efficiency is explained on the basis of fly-ash size distribution and mass concentration before and after the electrofilter.
