<P>PROBLEM TO BE SOLVED: To provide a lean fuel suction gas turbine capable of slipping-out of mixed gas, by performing efficient operation, while simplifying the whole constitution. Ž<P>SOLUTION: This lean fuel suction gas turbine has a compressor 1 for generating compressed gas G2 by compressing mixed gas G1 of the combustible limit concentration or less of mixing fuel and air, a first catalytic combustor 2 for burning the compressed gas G2 by catalytic reaction, a turbine 3 driven by combustion gas G3 from the first catalytic combustor 2, and a regenerator 6 for heating the compressed gas G2 introduced to the first catalytic combustor 2 by exhaust gas G4 from the turbine 3. A duct burner 7 for burning the exhaust gas G4 by a flame by first auxiliary fuel F1 is arranged between the turbine 3 and the regenerator 6. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
