PROBLEM TO BE SOLVED: To provide a gasification burner capable of preventing a side wall of a gasification furnace from being damaged, suppressing cost increase with a relatively simple structure.;SOLUTION: The gasification burner has a nozzle tip 4 including: a fuel injection nozzle 2 from which fine-particle solid fuel containing carbon and hydrogen is to be injected; and a plurality of oxidizer supply holes 3 disposed on the outer peripheral side of the fuel injection nozzle 2, from which an oxidizer is injected. The oxidizer supply holes 3 has a center line L3 inclined at a set angle θ toward the center line L2 of the fuel injection nozzle 2. The center line of the oxidizer supply holes 3 is inclined at a set angle α to the plane including the tip center C3 of the oxidizer supply holes 3 and the centerline of the fuel injection nozzle 2 in the same direction. The set angle α is set at an angle, such that the high-temperature region in the vicinity of the tip part of the fuel injection nozzle 2 formed when the center line of the oxidizer supply holes 3 is inclined at a set angle α has a narrower range than the high-temperature region formed when the set angle α is set at 0°.;COPYRIGHT: (C)2015,JPO&INPIT
