초록 ▼

In a turbine bucket having an airfoil portion and a root portion with a substantially planar platform at an interface between the airfoil portion and the root portion, a platform cooling arrangement including a cavity extending along the forward portion of the platform, and at least one inlet bore extending from a source of cooling medium to the cavity, and at least one outlet opening for expelling cooling medium from the cavity.

What is claimed is: 1. A turbine bucket having an airfoil portion and a root portion with a substantially planar platform at an interface between the airfoil portion and the root portion, a platform cooling arrangement including a cavity extending along the forward portion of the platform, forward of a leading edge of said airfoil portion and continuously from a pressure side to a suction side of said airfoil portion, at least one inlet bore extending from a source of cooling medium to said cavity and at least one outlet opening for expelling cooling medium from said cavity, wherein said at least one outlet opening comprises an exit opening defined at at least one longitudinal end of said cavity. 2. A turbine bucket as in claim 1, wherein said cavity is one of a cast-in cavity, a machined cavity and drilled hole. 3. A turbine bucket as in claim 1, wherein said cavity extends substantially in parallel to a leading edge of said platform. 4. A turbine bucket as in claim 1, wherein said cooling medium comprises steam and said source of cooling medium comprises a cooling circuit defined through one of said airfoil portion and said platform. 5. A turbine bucket as in claim 1, wherein said cooling medium comprises air and said cooling medium source comprises a pocket defined in said root portion. 6. A turbine bucket as in claim 1, wherein said exit opening is defined in a slash face of the platform and is directed to impinge upon a slash face of an adjacent bucket, thereby cooling the adjacent slash face. 7. A turbine bucket as in claim 1, further comprising a plurality of turbulators in at least one of said cavity and said inlet bore for augmenting heat transfer therein. 8. A turbine bucket having an airfoil portion and a root portion with a substantially planar platform at an interface between the airfoil portion and the root portion, a platform cooling arrangement including a cavity extending along the forward portion of the platform, forward of a leading edge of said airfoil portion and continuously from a pressure side to a suction side of said airfoil portion, at least one inlet bore extending from a source of cooling medium to said cavity and at least one outlet opening for expelling cooling medium from said cavity, wherein said at least one outlet opening comprises at least one film hole defined through said platform to communicate said cavity with a low static pressure region on a suction side of the airfoil portion. 9. A method of cooling a leading edge of a turbine bucket having an airfoil portion and a root portion, said airfoil portion being joined to a platform extending over said root portion, comprising: forming a cavity to extend along and adjacent to at least a portion of said leading edge, forward of a leading edge of said airfoil portion and continuously from a pressure side to a suction side of said airfoil portion; flowing a cooling medium from a source of cooling medium through at least one inlet bore to said cavity; and expelling cooling medium from said cavity through at least one outlet openings, wherein said at least one exit outlet opening comprises an exit opening at a longitudinal end of said cavity and further comprising directing spent cooling medium from said cavity against an adjacent bucket platform and purging a gap between adjacent platforms with said spent cooling medium. 10. A method as in claim 9, wherein cavity is one of a cast-end cavity, a machined cavity and a drilled hole. 11. A method as in claim 9, wherein said cavity is formed to extend in parallel to a leading edge of said platform. 12. A method of cooling a leading edge of a turbine bucket having an airfoil portion and a root portion, said airfoil portion being joined to a platform extending over said root portion, comprising: forming a cavity to extend along and adjacent to at least a Portion of said leading edge, forward of a leading edge of said airfoil portion and continuously from a pressure side to a suction side of said airfoil portion; flowing a cooling medium from a source of cooling medium through at least one inlet bore to said cavity; and expelling cooling medium from said cavity through at least one outlet opening, wherein said at least one outlet opening comprises a plurality of film cooling holes and wherein said expelling includes allowing cooling medium to escape from said cavity through said film cooling holes. 13. The method of claim 12, wherein said film cooling holes are located in said platform. 14. The method of claim 13, wherein said film cooling holes are on a suction side of the airfoil portion.
