Patent ID: 10526968

Abstract:
A gas turbine facility 10 of an embodiment includes: a combustor 20; a cylinder 80 dividing a space between a combustor casing 70 and the combustor 20; and a turbine 25 rotated by a combustion gas exhausted from the combustor 20. The gas turbine facility 10 includes: a heat exchanger 24 which cools the combustion gas; a pipe 42 through which a part of the combustion gas cooled in the heat exchanger 24 passes in the heat exchanger 24 to be heated and is guided to a space between the combustor 20 and the cylinder 80; a pipe 44 which guides another part of the combustion gas cooled in the heat exchanger 24 to a space between the combustor casing 70 and the cylinder 80; and a pipe 45 which exhausts a remaining part of the combustion gas cooled in the heat exchanger 24 to the outside.
