<p>A gas turbine combustor (12) is provided with a casing chamber (48), a combustor inner tube (42), a pilot combustion burner (44), main combustion burners (45) disposed so as to surround the pilot combustion burner (44), a fuel supply line for supplying fuel to the pilot combustion burner (44) or the main combustion burners (45), and an air extraction line (PA). Compressed air (Ain) from a compressor flows into the casing chamber (48), and the compressed air (Ain) and the fuel are combusted within the combustor inner tube (42) to generate combustion gas. The air extraction line (PA) extracts a part of the compressed air (Ain) flowing into the casing chamber (48) and supplies the extracted compressed air (Ain) to a pilot nozzle fuel line (FPa) or a main nozzle fuel line (FMa) in order to mix the extracted compressed air with fuel gas in the pilot fuel supply line (FP) or the main fuel supply line (FM).</p> |
