Definitions

  • EP 0 636 839 B1 discloses a rotary hearth furnace with such a furnace Plasma torch power source described.
  • the cylindrical Furnace chamber of the plasma rotary hearth furnace has one in the axis of rotation located, central casting opening through which the vitrified residues of decomposed waste are poured off.
  • a transferring arc plasma torch which with the bottom of the oven or parts thereof in electrical Contact, the energy required for decomposition is supplied.
  • the electrodes preferably have a dimension in cross-section between 5 and 60mm, preferably between 10 and 50mm.
  • the Length of the electrodes is preferably between 250 and 800 mm between 300 and 700 mm, or depending on the required Floor lining thickness determined.
  • Electrodes advantageously become a uniform size of the cross section chosen, thus a simple production of the lining the furnace floor is possible. Due to the necessary inclination of the furnace bottom towards the center, i. in the axis of rotation arranged casting opening can be the required length the electrodes used as a function of the distance to the casting opening vary.
