Especially in the lowest cyclone typical temperatures of about 700 ° to 950 ° C, briefly even higher temperatures occur, so that the dip tube is here exposed to a particularly high thermal stress and thus a high thermochemical and abrasive wear.
  • the nature of immersion tubes therefore presents the challenge of meeting the problems encountered in these extreme conditions.
  • the cylindrical wall is composed of a plurality of longitudinal segments, which are separately detachably attached to the Zyklonabscheiderdecke and are surrounded to support and maintain the ring shape of the dip tube at the bottom with a ring.
