Abstract
A gas turbine capable of minimizing the clearance between each of the rotor blades and partition ring, uses a structure in which the upstream thermally insulating ring is installed on the downstream blade ring.
Claims9
A gas turbine comprising:
- a plurality of rotor blades, which are disposed on the periphery of the rotor and rotate with the rotor;
- a plurality of partition rings which enclose the periphery of these rotor blades and forms a combustion gas flow path therein;
- and
- a plurality of blade rings which are disposed around the periphery of said partition rings and support said partition rings through a thermally insulating ring;
- wherein, when viewed from the axial direction of said rotor, the upstream thermally insulating ring, that supports the partition ring located relatively upstream among said plurality of partition rings, is installed on the downstream blade ring, which is positioned downstream of said blade ring, which corresponds to said upstream thermally insulating ring.
