PROBLEM TO BE SOLVED: To provide a radial lean direct injection burner. SOLUTION: A burner (2) for use in a gas turbine engine comprises a burner tube (4) having an inlet end (6) and an outlet end (8), a plurality of air passages (12) extending axially in the burner tube (4) for conveying air flows (26) from the inlet end to the outlet end, a plurality of fuel passages (14) extending axially along the burner tube and spaced around the plurality of air passages for conveying fuel (24) from the inlet end to the outlet end, and a radial air swirler (22) provided at the outlet end for feeding the air flows radially toward the outlet end and giving swirl to the air flows. The radial air swirler comprises a plurality of vanes (28) to feed and swirl the air flows and an end plate (36). The end plate comprises a plurality of fuel injection passages (38, 46) to inject the fuel radially into the swirling air flows. COPYRIGHT: (C)2011,JPO&INPIT |
