Definitions

  • the invention is directed to a device for the gasification of carbonaceous fuels with a discharge for slags in a slag bath.
  • the alkaline substances preferably evaporate from the slag, which causes the flow temperature of the slag increases substantially, so that in turn the burner performance is increased , which in turn leads to accelerated outgassing of the alkalis.
  • this object is achieved according to the invention in that the Vergaseraustragsö réelle is equipped with an electrically heatable Abtropfkante, wherein the heating is formed by an electrically en, ceramic resistance heater .
  • heated spouts are from the DE 195 40 641 C2 or the DE 196 54 402 C2 known. These solutions but concern other technical applications and are not readily transferable to the present technical field.
  • the drip edge of simple oxide or non-oxide ceramics or mixtures of corresponding ceramics is formed.
  • the ceramics used here may be Al 2 O 3 , Cr 2 O 3 , CaO, Fe 2 O 3 , HfO 2 , MgO, SiO 2 , SnO 2 , TiO 2 , ZrO 2 , AlN, MoSi 2 , SiC, BN, cermets, wherein the ceramics mentioned here can be used individually or in combination.
  • the invention also provides that the power supply is formed in the electrically heatable drip edge of a Stromzugot prepared for the power supply rod.
  • an electrically conductive ceramic such as MoSi 2
  • the power supply rod is enclosed by a non-electrically conductive ceramic.
  • An advantage of electrically conductive ceramics is also that the conductivity increases with increasing temperature, the ceramic is very slag and high temperature resistant and the control can be performed as a ceramic resistance heating.
  • the compound can, for example be carried out by an electrically conductive adhesive or it may already be provided for example during sintering corresponding elements for electrical connection.
  • Fig. 1 generally denoted by 1, very schematically illustrated carburetor for the gasification of carbonaceous fuels has in a refractory housing 2, a supply for the fuel to be gasified, designated 3, and supplies of other media 4, such as when starting the carburetor.
  • the forming in the combustion chamber designated 5 slag flows at the lower end in the direction of gravity from the carburetor in a not shown water bath, wherein the Vergaseraustragsö réelle is denoted by 6, the drip edge carries generally the reference numeral 7, the electrical leads are denoted by 8.
  • Fig. 2 is the structure of such a drip edge in the cutout specified.
  • the reactor wall 2 is lined, for example, with a ramming mass 9, which defines the Vergaseraustragsö réelle 6 and is provided on its inner wall with a ceramic heating element 10, wherein said heating element forms the drip edge 7.
  • the power supply 8 is formed by a power supply rod of electrically conductive ceramic, which is enclosed by a sleeve 11 made of an electrically non-conductive ceramic, which passes through the ramming mass, also electrically non-conductive.
  • a shrink tube 12 is still provided, which serves to seal the power supply rod to the container or the sleeve to prevent a short circuit between the container wall 2 and the power supply rod 8.
  • the indirect heating of the ceramic forming the drip edge 7 is shown, wherein the electrical resistance heater 10a can be formed, for example, of SiSiC, while the slag-resistant ceramic consists, for example, of Al 2 O 3 .Cr 2 O 3 . Visible, the ceramic resistance heater is positioned directly behind the slag-resistant ceramic, so that the ceramic is then transferred directly to the slag-resistant ceramic in the drip area of the carburetor, the ceramic resistance heating is separated from aggressive slag.
  • Fig. 4 shows Fig. 4 a directly heated ceramic ring 10, which is designed as a ceramic resistance heater, the material is chosen so that it is both resistant to slag and conductive.
  • the power supply rods 8 are suitably made of a material such as MoSi 2 , that is, the electrical resistance is lower than the resistance of the ceramic heat conductor, wherein the electrical resistance is temperature independent.
  • the material mentioned here can be used at temperatures of up to 1800 ° C.
  • the described embodiment of the invention is still to be modified in many ways, without departing from the spirit.
  • the invention is not limited in particular to a specific geometric shape of the resistance heating, and the drip edge forming the closing ring of the carburetor opening must not be integrally formed u. like. More.
