Abstract
PURPOSE: To increase cooling effect of the steam flowing into the balancing hole through vanes by furnishing the disc and nozzle situated on the steam outgoing side of vanes with concaves at the position mating with the nozzles steam incoming side.
CONSTITUTION: Concaves 14, 15, 16, 17 are furnished at nozzles 1, 2 and discs 5, 6 situated the mating vanes' 3, 4 steam outgoing side at the point corresponding to nozzle diaphragms 12, 13 situated on the steam incoming side, to increase the cooling effect of the steam. According to this arrangement, steam is expanded while the temperture drops because the steam, for example after passing through the vanes 3, 4, passes through the concaves 14, 15, 16, 17 in the discs 5, 6 and nozzle diaphragms 12, 13. That is to say, cooled steam flows into the rotor space 11 through balancing holes 9, 10 to cool the turbine rotor 7.
