<p>PROBLEM TO BE SOLVED: To provide a gas turbine installation capable of inhibiting oxidation of an oxidant supply pipe and reducing an emission concentration of carbon monoxide.SOLUTION: A gas turbine installation 10 according to an embodiment includes: a combustion chamber 20 burning fuel and oxidant; a turbine 21 rotating by combustion gas discharged from the combustion chamber 20; a heat exchanger 23 cooling the combustion gas discharged from the turbine 21; and a heat exchanger 24 removing water vapor from the combustion gas passing through the heat exchanger 23 to provide dry combustion gas. Furthermore, the gas turbine installation 10 includes: a pipe 41 introducing a part of the dry combustion gas to a pipe 42 for supplying the oxidant; a pipe 43 introducing mixture gas of the oxidant and the dry combustion gas to the combustion chamber 20 through the heat exchanger 23; a pipe 45 introducing the other part of the dry combustion gas to the combustion chamber 20 through the heat exchanger 23 as a working fluid; and a pipe 40 discharging a remainder of the dry combustion gas to an outside.</p> |
