A gas turbine facility 10 in an embodiment includes: a combustor 20; a fuel nozzle 21; a turbine 22; a heat exchanger 24 cooling the combustion gas. The gas turbine 5 facility 10 includes: a pipe 42 guiding a part of the cooled combustion gas to an oxidant supply pipe; a pipe 44 passing a mixed gas composed of the oxidant and the combustion gas through the heat exchanger 24 to heat it, and guising it to the fuel nozzle 21; a pipe 40 passing another part of the cooled combustion gas through the heat exchanger 24 to heat it, and guiding it to the combustor 20; a pipe 45 passing still another part of the cooled combustion 10 gas through the heat exchanger 24 to heat it, and guiding it to the fuel nozzle 21; and a pipe 46 exhausting a remaining part of the cooled combustion gas.
