This burner consists of an ordinary gas-jet over which is placed a metal tube about 5 inches long, perforated with holes at the bottom. When the gas is lighted, air is drawn through the holes, and mixes with the gas before ignition. From this air a plentiful supply of oxygen is obtained to allow complete combustion to proceed at once throughout the whole flame, and thus a smokeless, non-luminous flame of great heating power is obtained. The burner is used for various purposes, such as fire-lighting, cooking, ironing, heating, and soldering.
