Definitions

  • the present invention relates to a method for cooling solid residues of a combustion process according to the preamble of claim 1 and to a conveying device for carrying out this method.
  • Incinerators for burning solid fuels such as municipal waste, refuse derived fuels, biomass and other materials are well known to those skilled in the art.
  • Such systems include a combustion chamber in which the solid is burned while supplying so-called primary air.
  • the solids pass through various sub-processes from the inlet into the combustion chamber to the outlet, which can be subdivided roughly into drying, ignition, combustion and ash burning.
  • the lumpy residual solids present at the end of the combustion process are referred to as slag in the field of waste incineration.
  • Another part of solid residues may be present as fly ash, which is deposited by means of filters essentially in a downstream exhaust gas purification, viewed in the direction of flow of the exhaust gases.
  • the slag is discharged from the waste incineration plant by means of a de-scaling device, which as a rule comprises an intake shaft through which the slag from the combustion chamber falls into a tank filled with water.
  • the thus deleted slag is then about means ejected corresponding plunger and transported to an interim storage (bunker or container).
  • a device according to EP-A-0 252 967 which describes a device for continuous, dry Bodenascheabbow comprising a conveyor belt over which a controlled by a valve amount of air is discharged against the direction of the ash removal, so that the heat given off to the air is returned to the combustion chamber.
  • EP-A-2 665 971 and DE 10 2009 060 305 A1 required gas flow over the ash bed while a relatively large amount of air is introduced into the interior of the corresponding conveyor. In order to prevent an unfavorable for the burn-out and the energy balance temperature reduction in the furnace, but it must be ensured that as little cooling air enters the furnace.
  • EP-A-2 665 971 proposed a device for cooling of ashes from a firebox, which comprises a conveyor belt, the conveying surface is provided with openings to allow air flow through the conveying surface and the ash bed therethrough. In this way, a more efficient cooling with less air is to be made possible.
  • the mentioned disadvantages of the prior art in specific a strong dust and an impacted by false air energy balance of the incinerator are to be avoided.
  • the invention thus relates to a method for cooling of solid residues of a combustion process, which are applied to the conveying surface of a conveyor belt of a conveyor and conveyed towards a solids residue outlet, wherein during the promotion heat from the Residual residues is transferred to a gaseous cooling medium.
  • the conveyor belt is now subjected to cooling medium only on its side facing away from the conveying surface and is essentially impermeable to the cooling medium.
  • the temperature of the solids residue deposited on the conveyor is in the range of 200 ° C to 500 ° C, preferably 200 ° C to 300 ° C.
  • These solids residues are preferably cooled to below 150 ° C during production to the solids residue outlet, more preferably below 100 ° C.
  • the cooling medium according to the invention is gaseous. As will be explained below, air is preferably used as the cooling medium.
  • the heat transfer according to the invention or the resulting cooling of the solid particles thus differs fundamentally from technologies in which a liquid spray is used which due to the other material properties, in particular the higher density, compared to a gaseous cooling medium at reasonable cost only very unfavorable can be distributed to the surface to be cooled.
  • the cooling medium warmed up by contact with the conveyor belt is extracted on the side facing away from the conveying surface.
  • the warmed cooling medium is withdrawn from the space below the conveying surface and thus the heat is removed from the system.
  • the invention is thus based on the fact that the conveyor belt not only serves to convey the solids residues in the direction of the solids residue outlet, but also enables a spatial separation of the solid residues from the cooling medium or from the cooling system for cooling the solids residues.
  • the conveyor belt for the cooling medium is substantially impermeable and is acted upon only on its side facing away from the conveying surface with cooling medium.
  • necessary for the cooling cooling medium circulation is accomplished only in a space which is separated from the space in which the solid residues are arranged; a cooling medium-solid mixture is thus avoided according to the invention.
  • the cooling of the residual solids indirectly, i. can be ensured without direct contact between residual solids and cooling medium, incidentally, as little false air as possible passes through the cooling system in the furnace.
  • This makes it possible to better control the amount of air supplied to the combustion chamber for the primary combustion and thus the temperature in the combustion chamber, which has a positive influence on the energy balance of the incineration plant.
  • the heated cooling medium after extraction as heating means for heating the air required for combustion or otherwise use, for example in a neighboring district heating or a different type of energy recovery system.
  • the cooling medium is gaseous, in particular air. This can potentially corrosion problems, as they can occur in particular when using water as a cooling medium, effectively prevented, whereby the maintenance can be further minimized.
  • An anhydrous cooling process especially in combination with a dry discharge of slag, has the additional advantage that no water treatment costs are incurred.
  • a gaseous cooling medium is used.
  • no liquid spray is used, which according to the teaching of DE 10 2009 060 305 A1 is considered essential.
  • the resulting from the use of a liquid spray and also in the DE 10 2009 060 305 A1 described problems that the spray must be collected and cleaned before reuse, thus resulting according to the invention not.

  • the outlet openings over which the cooling medium is withdrawn, can be arranged at least partially at a similar distance from the surface of the conveyor belt to be acted upon.
  • the outlet openings are arranged at a distance of less than 30 cm, preferably less than 20 cm, and most preferably less than 10 cm from the surface of the conveyor belt to be acted upon. This ensures that the warmed up cooling medium is extracted early, which ultimately results in an optimized cooling.
