Abstract:
1. A turbine vane for a turbine for generating electrical energy, comprising: a hollow sectional element which extends radially with respect to a rotor and which has a transverse platform at each of its ends, whereby the sectional element is surrounded by hot working medium; a hollow inset, located in the sectional element, which stretches between the two platforms having a certain distance from the inside of the sectional element and having a base which faces one of the two transverse platforms; a coolant flowing in radially through the other platform into a hollow space of the inset and at least partially flowing out through baffle cooling openings provided on the inset aligned to the inside; and a recess that is provided in the platform located immediately opposite the base, wherein the inset stretches into the recess to establish zones in an extension of the inset having reduced predefined flow rates defining a particle trap in a base area of the inset.
