<p><P>PROBLEM TO BE SOLVED: To provide a burner capable of forming a combustion flame at a place distant from the tip, a glass fusion furnace therewith, and a method of forming a combustion flame. <P>SOLUTION: In this burner 10, an injection pipe for fuel gas 11, an injection pipe for incombustible gas 12 and an injection pipe for combustion gas 13 are combined with their pipe axes aligned in the same direction, and there is located the injection pipe for incombustible gas 12 outside the injection pipe for fuel gas 11 disposed on the center side of the combined injection pipe, or outside the injection pipe for combustion gas 13 so as to surround the injection pipe for fuel gas 11 or the injection pipe for combustion gas 13, and outside the injection pipe for incombustible gas 12 the injection pipe for combustion gas 13 or the injection pipe for fuel gas 11 is located so as to surround the injection pipe for incombustible gas 12. At the tip of the injection pipe for incombustible gas 12, a gas flow generation member 12C is set and it changes the injection direction of the incombustible gas from the tip inward or outward along the injection direction so that the injection direction of the incombustible gas crosses that of the fuel gas or the combustion gas. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
