Abstract: A torch tip for burning an oxidizer/fuel combustible mixture includes a head having multiple burners so as to produce a plurality of flames. The torch tip includes a venturi acting as a jet pump using fuel metered through an orifice to draw an oxidizer in the form of air entering from cross passages into the venturi and then into a mixing chamber in the torch tip. The combustible mixture then exits into the burners through flameholders which impart a swirling motion to the combustible mixture so that more complete combustion and a higher temperature is achieved. Each flameholder also includes a bluff body portion thereon for causing eddying of the combustible mixture in the burners, thereby further enhancing flameholding and completeness of combustion.
