PROBLEM TO BE SOLVED: To provide a reverse-flow injection mechanism having a coaxial fuel-air passage. SOLUTION: According to a specific embodiment, this system includes a fuel-air injection mechanism having a coaxial fuel and air passage to fuel and air injection openings 70, 72, 156, 157, 210, 211. The fuel and air injection openings 70, 72, 156, 157, 210, 211 are constituted to be formed at off-access positions of a gas turbine combustor 30, and the fuel and air passage to the fuel and air injection openings 70, 72, 156, 157, 210, 211 are oriented in the injecting direction not aligning with the flowing direction to a turbine 22 passing through the gas turbine combustor 30.
