PROBLEM TO BE SOLVED: To elevate the temperature of pressurized air supplied from a heat exchanger to a combustor with no increase in size of the heat exchanger. SOLUTION: A gas turbine has an inner duct 34 enclosing a combustor 3 for leading high-temperature pressurized air which have passed through a heat exchanger 5 into the combustor 3, and an outer duct 21 enclosing the heat exchanger 5 and inner duct 34 for leading low-temperature pressurized air discharged from a compressor 2 into the heat exchanger 5. Dilution ports 43 are provided for leading part of low-temperature pressurized air discharged from the compressor 2 from inside the outer duct 21 by way of the heat exchanger 5 to between the dilution region of the combustor 3 and a turbine 4. |
