Definitions

  • the invention relates to a method for operating a Bulk regenerator or regenerator according to the generic term of claim 1. It also relates to a regenerator the preamble of claim 6.
  • the object of the invention is a method for operating a Regenerators and a regenerator specify which one ensure improved service life.
  • the drained bulk material is advantageously in the Annulus returned. This will make the required minimum dumping height maintain bulk goods. When using high quality bulk goods can be recycled operating costs are reduced.
  • the device to collect at least one at an angle to the axis of the regenerator extending inclined surface, the inclined surface from the outside of the hot space facing away from the annular space Cold rust runs to an inner side facing the annular space and descends towards the bottom of the annulus.
  • the device can be provided with openings provided lid can be closed, the openings are designed so that a passage of gas is possible Passage of bulk material is impossible. This will create a Entrainment of individual bulk grains by the emerging Avoided gas flow.
