Title: Vertical temperature difference preventing structure for steam turbine casing
Inventor: NISHIGUCHI TOMOHARU
IPC: F01D25/26
Filed: 1989-01-24
Abstract: PURPOSE:To prevent a vertical temperature differential due to a natural convection in two internal and external casings from occurring by interconnecting an interspace between these casings to a labyrinth packing part with a bypass hole piercing through the internal casing. CONSTITUTION:A part of steam getting out of a step end of an internal casing 3 and giving turning force to a turbine axle 1 flows from an equalizing hole 8 to an equalizing chamber 7 lying between two internal and external casings 3 and 5. If so, steam in the equalizing chamber 7 flows into labyrinth packing 11 of a balance piston part 1a after passing through a bypass hole 23. Accordingly, a natural convection in the equalizing chamber 7 is kept back, thus a vertical temperature differential in these inernal and external casings 3, 5 is prevented. Since steam seals the labyrinth packing 11, an amount of steam leaking from a blade inlet chamber 15 to the labyrinth packing 11 is reduced. Consequently, the steam quantity flowing into the step end consisting of a stationary blade 4 and a moving blade 2 is increased as much as a portion for the decrement, so that the drop of turbine performance becomes lessened.
