Abstract
A tip burner for a flare comprises a diffuser () which is sealingly connected downstream to a shroud () comprising a tightly packed bed of granular material (). The stream of fuel and oxidizer flows to a diffuser where is mixed and tangentially swirled by a swirler () 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.
