The invention relates to an open type torch which comprises a dual-mode combustor arranged in a torch shell and comprising a flame stabilizing combustor and a main combustor, the upper portion of the main combustor is an output end, and a plurality of main flame holes are formed in the output end in the coiling direction; a heating pipeline is arranged on the upper portion of the heat return pipe, and the outer curved surface of the heating pipeline is tangent to the axial direction of a main flame hole in the output end of the main burner. The outer curved surface of the heating pipeline is tangent to the axial direction of a main flame hole in the output end of the main burner, so that a Coanda effect is formed on the outer curved surface of the heating pipeline, fuel gas is guided to form a uniform gas film, the contact area of the fuel gas and air is increased, the mixing efficiency is enhanced, flame centering stable burning of a torch is achieved, and the fuel gas is fully mixed. And the smokeless combustion threshold value is reduced. And meanwhile, the main flame hole is correspondingly shielded through the heating pipeline, so that wind and rain entering from the top of the torch are shielded, flames at the main flame hole are prevented from being blown out or extinguished, and the stability of the burning state of the torch is effectively guaranteed.

Burner (1) for a gas flare (20) for illuminating open spaces, in particular terraces or beer gardens, and / or for providing heat outdoors, which burner (1) extends along a longitudinal axis (2) and - comprises a burner tube (3) with at least one ventilation opening (4) extending transversely to the longitudinal axis (2). In order to ensure smooth operation despite precipitation, the invention provides that the burner (1) - comprises a gas distribution element (5) fluidly connected to the burner tube (3) and having a tubular base body (6) comprising at least one gas outlet opening (7) extending transversely to the longitudinal axis (2).
