A method for repairing a turbine blade (,) wherein the tip (,) of the blade is removed (,) and a replacement cap is attached by welding (,). The cap may consist of a plate (,) attached by welding and a squealer (,) formed by depositing weld material (,), as illustrated in FIG. 3. The plate and/or squealer may be formed from a material different from the material of the airfoil portion (,) of the blade in order to optimize the performance of the blade.

Method of repairing a turbine blade

A gas turbine that has turbine vanes that can be cooled with either steam or air includes a compressor that compresses air, a combustor enclosed within a shell and in flow communication with the compressor, a turbine in flow communication with the combustor and receiving hot gas from the combustor and turbine vanes. The turbine vanes having an airfoil, a shroud and a cooling circuit that cools the airfoil and the shrouds with either steam or air.

Cooling system for gas turbine vane

An apparatus for cooling the trailing edge portion of a gas turbine vane. Two radially extending passages connected to the outer shroud direct cooling fluid to a plenum formed about mid-span adjacent the trailing edge. Two arrays of cooling fluid passages extend from the plenum. One array extends radially outward toward the outer shroud while the other array extends radially inward toward the inner shroud. The plenum distributes the cooling fluid to the two arrays of passages so that it flows radially inward and outward to manifolds formed in the inner and outer shrouds. The manifolds direct the spent cooling fluid to a discharge passage.
