Definitions

  • the wear-resistant ceramic body which can be thick-walled in comparison to a wear protection coating and can therefore have a very long service life, can be centered and clamped against the metallic support body.
  • the ceramic fiber layer does not transmit any forces from the thermal expansion of the metallic support body of the coal dust annular gap nozzle, which can become 800 ° C, for example, when the rotary kiln is in operation, to the break-sensitive ceramic body.
  • the service life of the z. B. 4 mm thick-walled sleeve-like interchangeable ceramic body is so high that production downtimes of the rotary kiln operation, previously enforced by the replacement of worn parts of the coal dust annular gap nozzle, can be avoided entirely.
  • the rotary kiln burner of FIG. 1 has an annular channel (10) for the pneumatic transport of fine-grained coal dust.
  • the coal dust primary air suspension (11) occurs at a speed of z. B. 28 m / s from an annular gap nozzle (12), which diverges with a small angle to the outside.
  • a ring duct (13) is arranged concentrically around the coal dust duct (10), through which primary air flows, which flows at high speed, e.g. B. 350 m / s in the form of nozzle jets (14) from individual arranged around the circumference of the burner orifice Brennerdü sen (15) emerges.
