GAS TURBINE WITH AN OBTAINING ELEMENT IN THE REGION OF THE CROWN OF ALABES GUIA OR THE CROWN OF ALABES DE PALETA OF THE PART OF TURBINA.

摘要

Axial gas turbine (1) directed along a turbine shaft (10), comprising a compressor (3), a combustion chamber (5) and a turbine part (7), where in the part of turbine (7) are arranged crowns of guide vanes (11) and crowns of vane blades (13) axially consecutive in a hot gas channel (12), where in operation a hot gas (17) flows through the channel of hot gas (12) and where the guide vane crowns (11) and the guide ring, opposite to a vane vane crown (13), are cooled in each case with cooling air (53, 55) of different pressure level, whose pressure level is reduced in the direction of flow of the hot gas (17), characterized in that between a crown of guide vanes (17) and a guide vane support (79) or between a guide ring (51 ) and a guide vane support (79) there is provided a sealing element (35), which mutually seals the different pressure levels and extends integrally through a quarter of a circle (41), which runs perpendicular to the turbine axis as the central point.
