A tip burner for a flare comprises a diffuser (7) which is sealingly connected downstream to a shroud (9) comprising a tightly packed bed of granular material (13). The stream of fuel and oxidizer flows to a diffuser where is mixed and tangentially swirled by a swirler (8) located either in the diffuser or in a closed proximity to the diffuser inlet. The mixture flows next to the shroud where the granular material provides a tortious flow path for the stream, restructuring it aerodynamically and reducing its velocity, preferably to sub sonic level. A combustible mixture exits the shroud as multiple of jet, at low velocity and low turbulence. The mixture is ignited by a pilot burner installed above but in close proximity of the shroud, resulting in a stable flame which generates a low noise level.

The invention relates to a method for producing a molded body, having a silicon carbide support matrix and an integral carbon structure, wherein a base body on the basis of a powder mixture containing silicon carbide or silicon and carbon and of a binder is built in layers in a generative method, and wherein a pyrolysis of the base body is effected for realizing the molded body after the binder has been cured, wherein the carbon content of the carbon structure is adjusted by way of the pyrolysis of the binder and by way of the carbon content of the powder mixture or infiltration of a carbon material into the silicon carbide support matrix.
