Definitions

  • the invention relates to a method for influencing the properties of combustion residues from a Incineration plant, in particular a waste incineration plant, where the fuel is on a grate burned and the resulting combustion residues by appropriate combustion control on a elevated temperature are brought.
  • molten Combustion residues Due to the high temperatures in the treatment of Combustion residues in a smelting stage are molten Combustion residues due to low levels of organic Marked connections. While typical Slags from waste incineration plants still unburned, usually measured as loss on ignition, from 1 to 5% by weight show the loss on ignition of molten combustion residues at below 0.3 wt .-%. In addition, are molten Combustion residues due to small proportions characterized by leachable salts and heavy metals, because these either evaporated or in the case of cooling the Melt forming glass matrix are involved.
  • the object of the invention is the combustion process so too influence and regulate that completely sintered Slag with the desired quality without the use of downstream melting or glazing units obtained becomes.
  • a "completely sintered slag" becomes a material understood that consists of sintered and / or melted chunks, typically a grain size of at least 2 to 8 mm. These chunks consist of combustion residues of garbage by complete or superficial Melting are agglomerated.
  • the sintered or smelted pieces may be due to gas release during sintering or melting quite a porous Have structure.
  • the possible porosity of the fully sintered Slag is due to the fact that the temperature the molten slag in the fuel bed is not high is enough to have a sufficiently low viscosity and thus to cause expulsion of gas bubbles, which in the Glass technology is also referred to as Läutern. This is different the completely sintered slag of typical vitrified slags that are in downstream high-temperature process in crucible furnaces lined with refractory material or other melt aggregates.
  • the fully sintered slag can also constituents of waste, such as glass or metals, containing of the combustion process largely unaffected the Walk through grate, so in the narrower sense in the fuel bed neither melted nor sintered, but in terms of Burnout and leachable pollutants the desired properties have.
  • Residual slag will be the slag constituents below not sintered and / or melted are. Residual slag is characterized by a comparison to completely sintered slag smaller grain size as well higher loss on ignition and proportion of leachable pollutants.
  • the above task is based on a Method of the type described above according to the invention solved by the fact that the combustion control so led that is already in the fuel bed of the main combustion zone a sintering and / or melting the Combustion residue to slag takes place, and that still not or not completely sintered or molten Combustion residue at the end of the combustion process deposited and fed to the combustion process again become.
  • the basic idea of the invention is thus, on the one hand to influence the combustion process on the grate so that already a sintering and / or melting process the firing grate takes place in the main combustion zone, and that each still not sintered or molten Incineration residues are returned, at the second or third pass the desired Sintering and / or melting experience.
  • the focus of the inventive concept is therefore the sintering and / or melting process of the combustion residues already in the fuel bed of the main combustion zone, which was not thought possible until now. It is namely for mechanical firing grates extremely harmful, if liquid slag between the individual grate bars or Other movable parts of the Feuerungsrostes arrives. Out For this reason one has a melting of the slag on the Avoided rust and made sure that in the fuel bed the Melting temperature of the slag is not reached.
  • the sintered and / or melting in the upper part of the fuel bed instead, because from the top the largest heat effect by the Radiation of the flame body takes place and from below by supplying relatively cold primary combustion air the Temperature of the directly on the Feuerungsrost lying Material can be kept lower than on the top of the fuel bed. Because with such a combustion control not the entire incipient combustion residues in a completely sintered slag with the desired Quality can be converted, those are Combustion residue, which does not yet have the character of completely sintered slag, the combustion process fed again.
  • an oxygen enrichment of the primary combustion air to about 25 vol .-% to 40 vol .-% is made.
  • Another advantageous measure is that a preheating the primary air temperature to values of approx. 100 ° C to 400 ° C is performed. These measures may vary depending on Conditions are used separately or combined. Preferably, depending on the nature of the Burning the fuel bed temperature in the main combustion zone set to 1,000 ° C to 1,400 ° C.
  • the separation of not completely sintered from the completely sintered slag is by classifying the Slag after discharge from the combustion system possible by making a separation cut at a grain size from e.g. 2 to 10 mm lays.
  • the oversize corresponds to the completely sintered slag, while the undersized represents the fraction to be recycled.
  • the separation can be done either by sieving or in further advantageous embodiment of the invention by a combination of sieves and a washing process done.
  • the fine fraction with a particle size of less than 2 to 10 mm is returned to the combustion process. there can return by adding to the given Fuel or by immediate task on the Burning bed done. To avoid dust formation and Improvement of the handling ability can precede the fine fraction the return be pelletisisert or briquetted.
