Zusammenfassung:	PROBLEM TO BE SOLVED: To more reduce amounts of nitrogen oxide (NOx), carbon monoxide (CO) and unburnt hydrocarbon, as primary air pollution emission normally discharged from a gas turbine configured to combust hydrocarbon fuel, than conventional arts, and provide an automatic heat sensitive valve configured to passively control flow of fuel to a shaft upper fuel stage of the gas turbine.SOLUTION: Provided is a combustor for a gas turbine including: a shaft upper fuel stage of fuel injector; and a valve 66 configured to perform passive operation of selectively guiding supply of fuel to the shaft upper fuel stage of a fuel injector, based on characteristics of the fuel.SELECTED DRAWING: Figure 3 【課題】従来より、炭化水素燃料を燃焼させるガスタービンが通常発生させる主要な大気汚染排出物として、窒素酸化物（ＮＯｘ）、一酸化炭素（ＣＯ）、および未燃焼炭化水素の低減が求められている。本発明は、ガスタービンの軸上燃料段への燃料の流れを受動的に制御する自動感熱バルブを提供する。【解決手段】ガスタービン用の燃焼器であって、軸上燃料段の燃料インジェクタと、燃料の供給を該燃料の特徴に基づいて軸上燃料段の燃料インジェクタへと選択的に導く受動動作のバルブ（６６）とを含んでいる燃焼器を提供する。【選択図】図３
