Definitions

  • the invention relates to a rotatable around its longitudinal axis Heating chamber for solid goods, especially on a smoldering drum for waste, with a number housed inside, approximately parallel aligned heating pipes.
  • the heating chamber is used in particular as a smoldering drum for waste used for the purpose of thermal waste disposal, preferred after the smoldering process.
  • the plant for thermal waste disposal using the smoldering-burning process contains a as essential components Smoldering chamber (pyrolysis reactor) and a high-temperature combustion chamber.
  • the smoldering chamber uses a waste transport device abandoned waste in carbonization gases and pyrolysis residues around.
  • the carbonization gases and the pyrolysis residues are then, after suitable work-up, the burner of the high-temperature combustion chamber fed.
  • the high temperature combustion chamber creates molten slag that over a Deduction is removed and after cooling in glassy Form is present.
  • the resulting flue gas is fed through a flue gas line fed to a chimney as an outlet.
  • In this flue gas pipe are in particular a heat recovery steam generator as Cooling device, a dust filter system and a flue gas cleaning system built-in.
  • a smoldering chamber (pyrolysis reactor) is usually one rotating, relatively long smoldering drum used has a large number of parallel heating pipes on the inside where the waste is largely heated in the absence of air becomes.
  • the smoldering drum rotates about its longitudinal axis.
  • the longitudinal axis is preferably somewhat opposite the horizontal inclined so that the solid char at the exit of the Collect the smoldering drum and from there via a discharge pipe can be carried out.
  • When turning the waste through the heating pipes are lifted up and fall down again.
  • the transport of the solid Dust, chunks of carbon (coke), stones, bottles, Metal, ceramic parts, etc.
  • the object of the present invention is a heating chamber of the type mentioned in such a way that in the area a sufficiently large inside wall of the heating chamber Heating surface in the form of heating pipes for heating or pyrolysis of the discarded waste is available.
  • the risk of metal parts jamming and other solid chunks should be greatly reduced, so that the side facing the inner wall of the heating chamber individual heating tubes optimally used for heat transfer can be.
  • This object is achieved in that the Heating pipes - seen in cross section - in a practically closed one Row arranged along the wall of the interior are, and that the distance of the heating pipes (12b) from the wall of the Interior (13) and the mutual distance between the heating tubes (12b) smaller than is half the diameter of a heating tube (12b).
  • the invention is therefore based on the consideration that the Ensure availability of a high heating surface lets that the individual heating pipes on the inner wall if possible be arranged closely. In other words, to prevent that the chunks mentioned get stuck in the space the heating pipes on the inside of the drum a practically closed jacket, with a cylindrical one So smolder drum form a tube circle. The distances between the individual heating pipes should be as narrow as possible to get voted.
  • the main advantages are there too see that only fine waste material on the inner wall the heating chamber can fall, and that this inner wall mechanically is practically not burdened. It also follows a good one for a pyrolysis reactor or a smoldering drum Heat exchange from the heating pipes into the gas atmosphere and in the fines layer. The heat radially from the heating pipes is emitted to the outside, is therefore used very well.
  • the on the inner wall of the Heating chamber located heating pipes are protected against falling coarse material from so-called impact shells from one resistant material. This is in particular around semi-cylindrical shells. Such protection can also be provided for heating pipes that are - on straight or curved lines (seen in cross section) - inside extend into the heating chamber.
  • Training provided that - if necessary in the area of a such manhole blind pipes (dummies) in the series of Heating pipes are used.
  • dummies manhole blind pipes
  • These dummy pipes are pipes that are not flowed through by a heating gas. You are preferred arranged easily removable. This means that when the heating chamber is in operation, the row of heating pipes on the inner wall is closed while being inspected by the Personnel in the area of the manhole by dismantling the dummy pipes is interrupted.
  • the blind pipes mentioned above should be the same Have diameters like the peripheral ones arranged on the inner wall Heating pipes.
  • the distance of the (preferably closed) pipe circle from the The inner wall of the heating chamber should be as small as possible. He will usually be determined by design specifications, for example by attaching the heating and / or Blind pipes on end plates. Usually this distance can are between 20 and 40 mm.
  • the smoldering chamber 8 is in the Embodiment an internally heated, about its longitudinal axis 10 rotating smoldering or pyrolysis drum, which is a length of 15 to 30 m, which works at 300 to 600 ° C, which is operated largely with the exclusion of oxygen and which, in addition to volatile carbonization gas, is a largely solid pyrolysis residue generated.
