摘要： A gas turbine rotor steam gland (92) includes a steam inlet supply scroll (94) for supplying steam through radial slots (97) to an axially extending passage (84) in the rotor (14) for steam cooling of hot gas path component parts. The scroll (94) decreases in diameter in the circumferential direction of cooling medium flow to match its velocity with the surface speed of the rotor (14). An aft labyrinth seal (110) is provided about the rotor (14). Forwardly of the scroll (94), a plurality of labyrinth-type seals (102,104,106) are interspersed with extraction ports (96,98,100). The extraction ports (96,98,100) except for the final forwardmost extraction port (100), are maintained at a pressure below the pressure of the inlet supply steam whereby steam leakage past the seals (102,104,106) flows into the extraction ports (96,98,100) for removal. The final forward extraction port (100) is maintained at sub-ambient pressure such that final steam leakage past the forward seals and ambient air leakage past the forwardmost seal (106) combine and are extracted for the steam gland.
