Beschreibung
Zusammenfassung:	Stationary gas turbine arrangement with at least one turbine stage (6) comprising at least a first row of vanes (1) being mounted at a stationary component (13) arranged radially outside of the first row of vanes (1) and extending radially into an annular entrance opening (5) of the turbine stage (6) facing a downstream end of a combustor (4), wherein the stationary component (13) provides for each vane (1) a radially orientated through-hole (19) designed and arranged for a radial insertion and removal of the vane (1), and each of said vanes (1) comprises an airfoil (1') having at its one end directed radially outwards a contour (23) being adapted to close the through-hole (19) airtight by a detachable fixation means (20)., and method for performing maintenance work on such a stationary gas turbine.
