  • EP 0 636 839 B1 describes a plasma rotary hearth furnace.
  • the energy required to decompose the waste is supplied by a transferring plasma torch.
  • the cylindrical furnace chamber (centrifuge) of the rotary hearth furnace has a central pouring opening located in the axis of rotation for pouring the treated or. shredded and melted waste.
  • Fireproof material is arranged in the furnace floor and in the side walls.
  • Rotary hearth furnaces known in the genus are operated at such a rotational speed that due to the centrifugal galkraft collects the liquefied furnace filling in the outer area of the furnace bottom and the pouring opening remains free.
  • the furnace floor lining is not completely covered with melting material and is therefore directly exposed to the high arc temperatures of 10 ⁇ 000 to 15 x 000 ° C of the plasma torch.
  • the furnace base substructure and support structure of the cast stone shown in EP 0 636 839 B1 must be actively cooled.
  • cooling is relatively difficult during operation of the furnace and that the furnace floor lining is exposed to high thermal loads, particularly in the area of the pouring openings. This leads to a relatively short lifespan for the furnace floor lining, which results in frequent renewal of the furnace lining.
  • the high-temperature furnace according to the invention for burning and melting in particular radioactive waste contains at least one plasma torch arranged in the furnace and a centrifuge which can be rotated about an axis of rotation.
  • the centrifuge which has a furnace pan with a furnace bottom and side wall, has a pouring opening arranged in the furnace bottom, in the axis of rotation.
  • the furnace is characterized in that a filling device is provided for filling the pouring opening with, in particular, high-temperature resistant sand. Due to the backfilling sand backfilling of the pouring opening, the speed of rotation of the centrifuge can be set so low that the melting material covers the entire furnace bottom and not just the edge area. The furnace floor is completely covered and protected against overheating.
  • the furnace tub contains molten material, consisting of glass and residues of the treated waste such as concrete, ion exchange resins, as well as plastics and metals of all kinds, etc.
  • the energy required to operate the furnace is introduced via the plasma torch. In the immediate vicinity of the plasma torch temperatures of 10 '° to 15 000 ⁇ 000 ° Celsius are obtained. Due to the locally attainable high temperatures and the inert atmosphere, the furnace is ideal for the decomposition, burning and or melting of radioactive, highly toxic or other problematic waste.

  • a plurality of elongated electrodes which are arranged within a thermally and chemically resistant brick material, can also be used.
  • the furnace floor lining must also be particularly thermally and chemically resistant.
  • a pouring opening filled with filler sand has several advantages.
  • the rotary hearth furnace can be operated at a relatively low speed of rotation, since the furnace floor and thus the furnace floor lining can be completely covered.
  • the service life is increased and the risk of furnace breakthrough is reduced. This enables more efficient operation and in particular improves the introduction of energy into the furnace.
  • Clogging of the pouring opening is prevented by the filling sand filling in the pouring channel.
  • an unintentional, uncontrolled casting is avoided.
  • the melting material can undesirably measure out when the centrifuge rotation speed drops.
  • the pouring opening has a closing element for retaining the backfilling sand.

  • a filler profile can be movably connected to the filling device in such a way that the filler profile can be brought directly to the pouring opening, whereby a safe and precise filling is possible.
  • the filling device is arranged on the top of the furnace. This has the advantage that pourable fill sand can be brought into the pouring opening or the pouring channel simply by using the gravitational force. Under certain circumstances, supportive devices for shaking or vibrating can be used, which makes the filler to be filled more flowable.
  • the filling device but at least the filling profile, is particularly advantageously arranged in the axis of rotation of the furnace. This allows the filler sand to be poured safely into the pouring channel.
  • the furnace has a cleaning device, with the aid of which at least part of the filling sand can be removed from the pouring opening.

  • the cleaning device has a lance movable along the axis of rotation, the tip of which in the pouring opening is insertable.
  • the lance is preferably designed to be rotationally symmetrical, the diameter of the lance tip being equal to or smaller than the diameter of the pouring opening.
  • the lance is particularly advantageously arranged in an exit point outside the interior of the furnace. In this case, the lance is only in the interior of the oven for the cleaning process, which means that the lance only has to be exposed to the high thermal loads present there for a relatively short time.

  • Another aspect of the invention relates to a method for decomposing, burning and melting waste, in particular radioactive waste in a high-temperature furnace (rotary hearth furnace).
  • the rotary hearth furnace has at least one plasma torch arranged therein, a centrifuge which can be rotated about an axis of rotation and a pouring opening which is arranged in the furnace bottom of the centrifuge and in the axis of rotation.

  • filler sand is introduced into a preferably channel-like pouring opening.
  • the filling device has a dosing device for the intended filling with filler sand. It is preferred to fill just enough filler sand that the entire pouring channel is completely filled. However, it is also conceivable that more disposable sand is brought in, thereby an approximately hill-shaped pile of backfill sand is created in the furnace floor.
  • meltable and combustible waste can be introduced into the rotary hearth furnace and treated.
  • the waste is preferably burned under an inert atmosphere at high temperatures with the aid of the plasma torch and remaining solid particles are enclosed in the melting material.

  • the pouring opening is first closed with the aid of a closing element.
  • the pouring opening or pouring channel is then filled with filler sand.
  • the closing element on the one hand ensures that the backfilling sand is retained in the pouring channel, and on the other hand it prevents unintentional outflow of available sand during operation. Only after the closing element has been opened can the available sand be removed from the pouring opening.
  • the closing element rotates about its own axis and is preferably attached to a lifting / swiveling arm which in turn is articulated to the furnace structure.
  • the closing element can be held in position by spring force.

  • the pouring opening is cleared for emptying the reactor by opening the closing element arranged under the pouring channel and then at least partially removing the available sand in the pouring channel with the aid of an ejection or cleaning device.
  • opening the closing element After opening the closing element is under Under certain circumstances, part of the pourable available sand is already flowing out of the pouring channel.
  • the speed of rotation of the rotary hearth furnace is increased in such a way that the pouring opening is no longer covered by melted material due to the centrifugal effect. Then the available sand is removed from the pouring opening with the help of the ejection or cleaning device.
  • the filling sand residues still present in the pouring channel are expelled with a movable lance of the cleaning device.
  • the turning speed of the rotary hearth furnace is then reduced again for casting. This ensures a controlled pouring of melted material.
  • the flow rate of the melting material can be controlled by the choice of the rotation speed.

  • Another aspect of the invention relates to a method in which melt material residues are only removed in the center of the pouring opening in such a way that melt material residues remain in the pouring channel as cladding or sheathing. This makes it possible to operate the furnace or the rotary hearth furnace with an open pouring channel.
