GASIFICATION BURNER, AND METHOD OF SUPPLYING FUEL FOR GASIFICATION BURNER

PROBLEM TO BE SOLVED: To reduce heat load from a gasification furnace in the whole area of a burner tip section and to elongate a service life of a gasification burner. SOLUTION: This gasification burner 50 includes a coal supply pipe 52 for transporting coal into the gasification furnace by airflow, an oxidant supply pipe 54 concentrically disposed at an outer side of the coal supply pipe 52, and supplying an oxidant into the gasification furnace, nozzle chips 56 disposed on the coal supply pipe 52 and the oxidant supply pipe 54, and having a coal supply hole communicated with the coal supply pipe 52, and a plurality of oxidant supply holes communicated with the oxidant supply pipe 54, and a cooling pipe 58 disposed at an outer periphery of the oxidant supply pipe 54 with a clearance to the oxidant supply pipe 54, and a gas 70 is injected into the gasification from the clearance between the oxidant supply pipe 54 and the cooling pipe 58. Swirl blades 60 are disposed to inject the gas 70 into the gasification furnace while swirling the gas to a shaft of the coal supply pipe 52. COPYRIGHT: (C)2011,JPO&INPIT
