Abstract (en)

[origin: EP2098781A2] The torch has flowing-/limiting elements (3a-3c) that are circular in shape and defined by a combustion chamber (2), where the device is cylindrical in shape. The limiting elements are spirally arranged to form a radial gap (6) and are made from fire-resistant glass. Flow openings with guiding elements are provided in the limiting elements. Fresh air flows tangentially into the chamber through the gap or the openings and is directed into the chamber in a circumferential direction for producing flame vortex (8).
