Abstract
PURPOSE: To cool the entire blade body efficiently with a relatively small amount of cooling liquid, by spraying cooling liquid from apertures formed in the wall of coolant guiding tubes extended inside the blade body.
CONSTITUTION: When cooling liquid is introduced into coolant inlet passage 17, cooling liquid is carried into coolant guiding tubes 15 and compressed by the centrifugal force. By the compression force, cooling liquid is issued from apertures 18 in the form of mist and ejected onto the inner surface of cooling passages 13. Mist of cooling liquid thus ejected onto the wall of cooling passages 13 is evaporated by depriving heat from the inner surface of passages 13. Since much heat is deprived by evaporation cooling than by liquid cooling, the body 11 of rotor blade can be cooled more efficiently. Steam produced in cooling passages 13 is discharged to the outside through passage 14. Thus, the blade can be cooled efficiently with a smaller amount of cooling liquid as compared with the fully liquid-cooling method.
