Title:
GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2014/033972
Kind Code:
A1
Abstract:
This gas turbine has a first blade ring section (20f) to which a first stationary blade (11a) is attached and a second blade ring section (20g) to which a second stationary blade (11b) is attached, that are integrally formed and form a combined blade ring (20y). A second upstream-side pressing member (50g) is arranged on the upstream side of a second upstream-side heat-insulating ring (40g) that attaches, to the combined blade ring, a first split ring (30a) and a second stationary blade stage (10b) arranged on the downstream side of this first split ring. The pressing member presses and fixes the heat-insulating ring on to the downstream side and the sealing properties of packing (71b) are maintained, as a result of attaching the pressing member to the blade ring section.
