가스 터빈(1)은, 압축 공기를 생성하는 압축기(2)와, 압축 공기가 도입되는 차실(5)과, 연소 가스를 생성하는 연소기(3)와, 연소 가스에 의해서 구동되는 터빈(4)과, 압축기(2)에 대해서 독립으로 운전 가능한 서브 압축기(62)와, 차실(5) 내의 공기를 추기하고, 서브 압축기(62)로 승압한 후에 열교환하는 열교환기(61)를 갖고, 열교환된 공기를 연소기(3)의 통체(30)의 냉각 통로(31)에 도입하는 연소기 냉각 계통(6)과, 연소기 냉각 계통(6)을 유통하는 공기를 추기해서 연소기(3) 내에 도입하는 연소기 공기 도입 계통을 포함한다. There is provided a gas turbine (1) including a compressor (2) that generates compressed air, a casing (5) into which the compressed air is introduced, a combustor (3) that generates a combustion gas, a turbine (4) that is driven by the combustion gas, a combustor cooling system (6) that has a sub-compressor (62), which is able to be operated independently of the compressor (2), and a heat exchanger (61), which extracts air in the casing (5) and causes the air to exchange heat after the sub-compressor (62) has increased a pressure of the air, and that introduces the air, which has exchanged heat, into a cooling passage (31) of a cylindrical body (30) of the combustor (3), and a combustor air introducing system that extracts air flowing in the combustor cooling system (6) and introduces the air into the combustor (3).
