  • the controlled supply of combustible dust in an entrained-flow gasifier is described, for example, in DE 10 2005 047 583 A. It is known to convert the fuel with the burners installed in the vertical gasifier wall and substantially horizontal, wherein the fuel of finely divided or dusty ( ⁇ 0.5 mm) fuel particles, e.g. Coal, Petrokoks, biological waste and other fuels is reacted with oxygen-containing gasification agents under elevated pressure at temperatures above the slag melting point.
  • finely divided or dusty ( ⁇ 0.5 mm) fuel particles e.g. Coal, Petrokoks, biological waste and other fuels is reacted with oxygen-containing gasification agents under elevated pressure at temperatures above the slag melting point.
  • a carbonaceous fuel is reacted with an oxygen-containing gas, wherein the oxygen-containing gas is supplied to the sub-stoichiometric ratio, so as to obtain a hydrogen and carbon monoxide-containing product gas.
  • the fuel-oxygen ratio is set in a narrow range.
  • the pressure gasification burner with coaxial channels are usually used, with a mixing of the fed media not in the burner, but only in the carburetor.
  • An example of a burner used in a pressure gasification plant is shown in detail, for example, in EP 0 437 698 A1.
  • the supply of the burner with fuel usually takes place from a slightly above the gasifier pressure storage tank by means of dense phase conveying.
  • dense phase conveying a pneumatic conveying is referred to, wherein the carrier gas does not transport the fuel particles as individual particles, but in the form of dense fillings or plugs that fill the entire pipe cross-section.
  • dense-phase conveyors have velocities of 4 to 6 m / s, the high solids loading of the gas stream leading to a nevertheless high transport volume.
  • the dense phase conveying is very gentle on materials and, above all, is less susceptible to interference when it comes to adhesive or moist goods to be transported.
  • the quality of the gasification is significantly influenced by the uniformity of the coal supply to the burner. While variations are detected and taken into account over longer time intervals (for example, by intended control interventions or by changing the feed coal, etc.), very short-term fluctuations in the conveying quality (conveying density and speed) can not be compensated.
  • the dense phase conveying in the broadest sense is a fluidized gas / solids mixture
  • the fluctuations in density and velocity typical of the fluidized bed are also to be observed here.
  • These can only be influenced by indirect measures such as the design of the supply to the delivery line.
  • the storage tank which supplies the burners via a feed line
  • the burners are due to the vertical design of the carburetor at a much higher level.
  • the installation of the reservoir "bottom” is inexpensive, especially if the required fuel spill into the feed tank based on gravity flow and therefore must be positioned above the reservoir.
  • Object of the present invention is to provide a method described above in such a way that a significantly homogenized supply of coal to the burner is possible, whereby the short-term fluctuations minimized and thus the gasification quality is improved and the control of the amount of coal to the burner is made more effective.
  • this object is achieved according to the invention in that the fine-grained to dust-like fuel from a positioned below the burner level storage tank initially promoted to a level above the burner level and is subsequently homogenized in a downward direction to the burner line. It has been found that a uniformity of the fuel / gas mixture transported in the dense stream is achieved by the inventive method, which is significantly better than, for example, the promotion by horizontally extending lines. Due to the homogenization in the downpipe in front of the burner, the fuel particles are accelerated by the gravitational attraction, whereby any gas bubbles in the mixture are filled with fuel during the fall.
  • Embodiments emerge from the subclaims. It can be provided that the homogenization takes place in a downwardly directed line whose length corresponds to at least five times the diameter of the pipe.
  • the fuel is homogenized in a down pipe guided from a manifold, wherein the downpipe is oriented at angles ⁇ 20 °, preferably in 0 ° to the vertical.

Abstract

La présente invention concerne un procédé et un dispositif destinés à l'homogénéisation et à la régulation d'un combustible solide transporté de façon pneumatique par un courant de transport dense arrivant dans un gazéificateur utilisé pour la production de gaz de synthèse. L'objet de la présente invention est de permettre une arrivée bien homogénéisée du charbon jusqu'au brûleur, ce qui permet de réduire au minimum les fluctuations brèves, et donc d'améliorer la qualité de la gazéification, et d'obtenir une régulation plus efficace de la quantité de charbon fournie au brûleur. À cet effet, le combustible, qui va des fines aux poussières et qui est prélevé dans un réservoir d'alimentation (1) disposé au-dessous du niveau du brûleur, est transporté d'abord à un niveau situé au-dessus du niveau du brûleur, à la suite de quoi il est homogénéisé dans un conduit descendant vers le brûleur (4a, 4b).
