Burner and gas turbine combustor

摘要

A burner (100) is provided that has high flame stability and reduces NOx emissions. In the burner (100), air holes (34, 35) of an air hole member (31) have a central axis inclined relative to a burner central axis. The leading end portion of a first fuel nozzle (33) is configured to be able to suppress turbulence of air-flow flowing on the outer circumference side of the first fuel nozzle (33). The tip of the first fuel nozzle (33) is located on a fuel jetting-out directional downstream side of the inlet of the fuel hole (35). The tip of the second fuel nozzle (32) is located on a fuel jetting-out directional downstream side of the air hole inlet.
