PROBLEM TO BE SOLVED: To provide a multi-fuel handling gas turbine combustor capable of maintaining excellent low emission performance for premix combustion by a main burner and burning hydrogen gas at low NOx emission by a reheating burner.SOLUTION: A multi-fuel handling gas turbine combustor comprises: a main burner 12 supplying premixed gas M containing a first fuel F1 to a first combustion region S1 within a combustion chamber 10 to burn the premixed gas M; and a reheating burner 20 supplying premixed gas containing a second fuel F2 different in composition from the first fuel F1 to a second combustion region S2 downstream of the first combustion region S1 within the combustion chamber 10 to burn the premixed gas. The first fuel F1 is hydrocarbon-based and the second fuel F2 is gas containing hydrogen at a concentration exceeding a hydrogen stable burning limit concentration. |
