For this purpose, it is necessary that the materials are matched accordingly. The choice of materials and the formation of the weld in this area leads to increased design effort. In addition, therefore, in the high temperature loaded and flowed through by aggressive media mouth region of the primary or burner tube due to the presence of welds increased repair and susceptibility to failure and impaired by these conditions lifetime is to be expected.
  • the invention is based on the object to provide a solution that makes it possible to form the mouth region of a generic burner durable and / or structurally simpler.
  • this object is achieved in that the Lucasabweiskehle and the stabilizing ring are formed as a one-piece component.
  • This component can then be welded, for example, by means of a circumferential weld on the end face of a burner tube or primary air tube, so that only one weld is present in the region of the mouth. Since only one weld is required, the burner can be made faster than a burner of the prior art, in which two welds are necessary. In addition, it is thereby possible, the weld with respect to the air flow in the burner or primary or secondary air tube further upstream, d. H.
  • the inventively designed burner region is characterized more durable, d. H. less susceptible to interference and repair and structurally simpler.

This edge, which projects into the stream of primary air and pulverized coal, ensures that the coal particles encounter resistance before they leave the primary air tube 1, are thereby delayed and are accelerated again by the gas flow in the direction of the center of the burner tube.
  • the core air tube 6 which sets the primary air coal dust flow in a rotational flow.
  • This ring 4 has the shape of an internal toothing and protrudes into the flow region of the pulverized coal, so that the coal particles collide against a resistance before leaving the primary tube or primary air tube 1. Due to the impact on the ring 4, the carbon particles are braked sharply.
