Abstract
In an axial flow gas turbine (), a reduction in cooling air mass flow and leakage in combination with an improved cooling and effective thermal protection of critical parts within the turbine stages of the turbine is achieved by providing, within a turbine stage (TS), devices (-) to direct cooling air that has already been used to cool, especially the airfoils of the vanes () of the turbine stage (TS), into a first cavity () located between the outer blade platforms () and the opposed stator heat shields () for protecting the stator heat shields () against the hot gas and for cooling the outer blade platforms ().
