摘要
A gas turbine combustor (3) having a combustion chamber (12) for mixing a low heating value fuel gas (60) and air (102) together to burn the gas (60), and a burner (300) disposed upstream of the combustion chamber (12) for supplying a gas (60) and air (102) to an interior of the combustion chamber (12) to hold a flame, wherein: the burner (300) is provided with a first swirler (201) in which gas holes (401) and air holes (402) are alternately formed in a circumferential direction thereof; a first gas (60) is supplied to the gas holes (401) in the first swirler (201) and air (102) is supplied to the air holes (402); and a swiveling flow path is formed in each gas hole (401) and each air hole (402) in the burner (300) to swivel the gas (60) and the air (102) and supply the gas (60) and the air (102) to the interior of the combustion chamber (12), a second gas hole (500) is formed in the swiveling flow path in at least one of the air holes (402) and the gas holes (401), and a second high heating value fuel gas (80) is supplied through the second gas hole (500).
