Abstract

PURPOSE:To improve thermal efficiency during partial load running, by a method wherein a regulating valve is located in a cooling air feed line running from a compressor to a gas turbine, and an amount of cooling air fed to the gas turbine is controlled according to the load of the gas turbine. CONSTITUTION:Cooling air extracted through an extraction hole 10 of a compressor 1 is fed in a gas turbine 3 through a plurality of air pipings 11. In this case, A regulating valve 13 is located in the middle of each air piping 11. Operation of the regulating valve 13 is controlled by a temperature control device 14 based on a detecting signal from a temperature detector 15 to regulate an amount of cooling air fed in the gas turbine 3. Namely, an amount of cooling air fed in the gas turbine 3 is controlled according to the load of the gas turbine 3. This constitution prevents the excessive feed of cooling air, for example, during partial load running of the gas turbine 3, and maintains thermal efficiency at a high value.
