Abstract

In the device for removing ashes, there are arranged beneath a sieve 2 alternating suction boxes 7 and vibration generators 3 which produce local vibrations of between 20 and 60 Hz in the sieve. The fluid containing the fine material is more effectively removed through the suction boxes 7. <IMAGE>
