PROBLEM TO BE SOLVED: To improve the output of a gas turbine with a simple means and reduce the amount of emission of deleterious material from a gas turbine by effectively using the total air quantity in a multistage gas turbine. SOLUTION: The gas turbine 5 is provided with a main combustion chamber 10, a cooling system for cooling of at least a static blade 26, 29 and a guide ring 28 of various turbine blades 25, 27, and a main gas passage. An auxiliary combustion chamber 34 is arranged downstream of the main combustion chamber 10 in the main flow direction H of the high temperature gas, and the cooling air 15 used for cooling of a turbine stage 25 of the gas turbine 5 arranged upstream of the auxiliary combustion chamber is supplied into the auxiliary combustion chamber 34.
