Abstract: PROBLEM TO BE SOLVED: To very easily adapt a stationary vane 14 to an individual service condition at particularly inexpensive apparatus cost and spare part replenishing cost, in the stationary vane 14 in a gas turbine 1 having a vane body 28 of a single body structure composed of a vane leg 18, a shroud 26 and a vane-shaped part 24 extending between its both. SOLUTION: This gas turbine is provided by joining a flow guide body 30 having a front guide vane 32 places at the front end in the vane-shaped part 24 in the flowing direction of a working medium M of the gas turbine 1 to the vane body 28. At least two stationary vanes 14 of a stationary vane cascade have the flow guide body 30 having different front guide vanes 32. This flow guide body 30 is made of a heat resistant material larger than the vane body 28. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: The guide vane (14) has a vane base (28) designed as a single piece and including a vane root (18), a cover plate (26) and a vane blade (24) extending between the vane root and the cover plate. A flow guide body (30) located on the vane base is attached to a pre-guiding blade (32) which is connected upstream of the vane blade with respect to a flow direction of a working fluid of a gas turbine. The flow guide body is made of a material temperature-firm compared to the vane base.
