Abstract
A gas turbine () includes a combustion chamber () followed by a stator airfoil row () defining a plurality of guide vanes and separated by the combustion chamber () by a first gap (), and a rotor airfoil row () separated by the stator airfoil row () by a second gap (). The stator airfoils () of the stator airfoil row () are connected to guide vane boxes () collecting a cooling fluid (A) and injecting it through nozzles () in the second gap () to make it to enter rotor airfoil inlets (). The guide vane boxes () are provided with passages () connecting a zone () upstream of the guide vane boxes () to a zone () of the second gap () downstream of the guide vane boxes (). Moreover, the mouths () of the passages () facing the rotor airfoil row () are closer to a hot gases path than the nozzles ().
