Definitions

  • the invention relates to a burner unit for dusty solid fuel having a first tube for conveying the solid fuel in a first conveying direction, wherein a deflecting body for deflecting the emerging from the first tube solid fuel jet is arranged in extension of the first tube. Furthermore, the invention relates to a burner assembly for a furnace, in particular for a ring-shaft furnace for burning limestone.
  • Burner units of the type mentioned are known from the prior art. They are preferably used in shaft furnace systems, for example in annular shaft furnaces for burning limestone.
  • the particular procedural challenge is to achieve the fullest possible implementation of the dusty fuel - this can be, for example, petroleum coke dust - in hot gases in order to use the energy content of the dusty solid fuel as completely as possible.
  • the deflected fuel stream then mixes with another oncoming air stream, so that an approximately complete mixing of rod-shaped solid fuel and combustion air and thus a complete combustion of the fuel is ensured.

On the other hand, it is ensured by the use of the impact tube surrounding the first tube, that the fuel jet undergoes the desired renewed change of direction, but without the risk that parts of the fuel jet strikes back into the burner unit and settle there, which is associated with the known problem.
  • the baffle body can assume all geometric shapes which ensure that the solid fuel jet initially deflected by the deflecting body is deflected again in the first conveying direction, without the overall aerodynamics of the construction being changed significantly overall, particularly when installed in a corresponding burner housing.
