Definitions

  • the invention is directed to a fluidized bed gasifier, in particular high temperature Winkler carburettor, with a cyclone separator associated with the gasifier head and with a solids return line from the cyclone to the bottom of the gasifier.
  • Winkler carburettors are known, for example, EP 0 264 810 or DE 11 2009 000 287 or WO 2009/145724.
  • a fluidized bed is generated and at least a portion of the dust discharged with the raw gas a cyclone separated and returned to the carburetor (DE 44 13 923 AI).
  • heating torches are provided in the lower funnel area, which serves for the ash discharge, which bring the refractory lining of the carburetor to the necessary temperature.
  • the storage heat of the lining makes it possible to ignite a fluidized bed material (charcoal, hearth furnace coke) and thus to enable the starting process.
  • the object of the present invention is to avoid the disadvantages described above, i. to make an expansion of Auffilbrenner dispensable.
  • this object is achieved according to the invention in that in particular in the lower region of the carburetor planar Auffilbrenner are provided which have a metallic or ceramic cellular structure.
  • the invention also provides in an embodiment that the flat heating torch are positioned further up in the cylindrical portion of the carburetor.
  • the burners can be positioned in the post-gasification zone, so that less purge gas is required, because there the solids content is lower.
  • the AufMapnner can advantageously for example from a Metal fabric may be formed from a high-temperature steel or else, as the invention also provides in an embodiment, of a ceramic with a cellular structure.
  • a high temperature steel may be Fe-Cr-Al based alloys that have high corrosion and high temperature resistance.
  • the resistance is improved by the presence of an oxide layer on the surface, in particular by Al 2 O 3, whereby this oxide layer forms spontaneously on the surface due to the oxidation of Al to Al 2 O 3 on its own.
  • Temperatures between 1000 ° C and 1200 ° C are preferred for such pre-oxidation.
  • a further embodiment of the burner according to the invention may consist in that for the formation of the burner metal oxides, such as Al2O3, as already mentioned above, or CaO, CeO, Cr 2 0 3 , Fe 2 0 3 , Hf0 2 , MgO, Si0 2 , Zr0 2nd as single components or as a mixture, non-metal oxides such as BN, BC, MoSi 2 or SiN as single components or as a mixture or metals based on Fe-Cr-Al with additions of Sc, Y, Ti, Zr, Hf, V, Nb, Ta and Lanthanides are used.
  • the burner metal oxides such as Al2O3, as already mentioned above, or CaO, CeO, Cr 2 0 3 , Fe 2 0 3 , Hf0 2 , MgO, Si0 2 , Zr0 2nd as single components or as a mixture
  • non-metal oxides such as BN, BC, MoSi 2 or SiN as single components or as a mixture or
  • the burners may be designed according to the invention, for example, as rectangular or trapezoidal surface elements for installation in the funnel wall of the reactor, without the invention being limited to this particular shape.
  • the combustion media can be air, oxygen and moderator (C02, N 2 ), which can be provided as flushing media eg C0 2 , N 2 , synthesis gas or flue gas.
  • the burners can be stoichiometric or substoichiometric.
  • 1 is a simplified representation of a section through a high-temperature Winkler carburetor and in
  • Fig. 2 shows an enlarged detail of the ash hopper with AufMultibrennern in a simplified representation.
  • a high temperature Winkler carburetor is formed by a carburetor body 2 of refractory masonry, which is provided in the direction of gravity at the bottom with a conical outlet region 2a.
  • a supply line 3 is positioned to a cyclone 4, wherein the cyclone 4 passes the separated solid particles via a return line 5 in the lower portion 2a of the carburetor 2.
  • Feed lines for introducing gasification components and for exit into a fluidized bed are shown in FIG. 1 only indicated and designated 6 to 8.
  • the heating torches 9 according to the invention are positioned, this region in FIG. 2 enlarged, but also simplified.
  • the AufMapnner 9 have on their surface on a cellular structure 10, through which flow the combustion gases or, depending on the operation, purge gases which are supplied via lines 11 to the flat burners.
  • This cellular Structure may be provided, for example, by a metal mesh formed of high-temperature steel or also of ceramic having a corresponding cellular structure.
  • the flat burners may be rectangular or trapezoidal, without the invention being limited to these specific designs.
  • Fig. 1 is still indicated that the burner 9a can be positioned further up in the cylindrical part of the carburetor body 2, as described above.

Abstract

L'invention concerne un gazéifieur à lit fluidisé, en particulier un gazéifieur Winkler haute température comprenant un séparateur cyclonique ou centrifuge qui est associé à la tête du gazéifieur, ainsi qu'une conduite de remise en circulation de matières solides du séparateur cyclonique jusqu'à la zone inférieure du gazéifieur. L'objectif de cette invention est de supprimer les inconvénients connus, à savoir de rendre le démontage du brûleur de chauffage non nécessaire. A cet effet, des brûleurs de chauffage plans (9) comportant une structure cellulaire métallique ou céramique (10) sont prévus en particulier dans la zone inférieure (2a) du gazéifieur.
