PROBLEM TO BE SOLVED: To provide a flame stabilizer capable of reducing thermal stress without changing a material or performing heat insulation. SOLUTION: The flame stabilizer has a structure comprising an inner cylinder to store a burner gun to feed fuel into a furnace, an outer cylinder, a rib to connect the inner cylinder to the outer cylinder, and a truncated conical part (a cone) to be coupled with a tip of the rib, and is formed of heat-resistant alloy steel. The cone is cut at a middle position of a rib coupling part with an adequate space formed therein. COPYRIGHT: (C)2004,JPO&NCIPI
