Embodiment Construction

[0034] exist figure 1 , reference numeral 1 designates a gas turbine arrangement for the production of electrical energy, which extends along a longitudinal axis A (for clarity only, figure 1 One half of the device is shown in , since the device is symmetrical about axis A).

[0035] The plant 1 comprises a combustor 2 , a compressor 3 and a gas turbine 5 .

[0036] The gas turbine 5 extends along a longitudinal axis A and is provided with a shaft 6 (also extending along the axis A) to which the compressor 3 is also connected.

[0037] The gas turbine 5 comprises a working expansion channel 7 in which the hot gas working fluid from the combustor 2 flows in a direction D. The working expansion channel 7 has a radially increasing section along the axis A in the direction D.

[0038] The compressor 3 comprises a working compression channel 8 in which external air is compressed and flows in a direction D. The end of the working compression channel 8 is connected to the burner ...

Abstract

The invention relates to a vane carrier for a gas turbine plant and a gas turbine plant comprising the same. Specifically, the vane carrier for a gas turbine plant extends along a longitudinal axis (A) and comprises at least one clearance control cavity (29) which extends transversally with respect to the longitudinal axis (A).

Description

[0001] priority statement [0002] This application claims priority from European Patent Application No. 17179199.9 filed 30 June 2017, the disclosure of which is incorporated herein by reference. technical field [0003] The invention relates to a vane carrier for a gas turbine arrangement and a gas turbine arrangement comprising said vane carrier. In particular, gas turbine installations are electrical power production installations. Background technique [0004] It is well known that in gas turbine installations a spacing is required between the rotating blade tips and the stator vane carrier in order to enable relative movement between the rotor blade tips and the stator vane carrier. [0005] However, during operation of the gas turbine plant, the rotor part and the stator part have different responses to temperature changes because they are made of different materials and also because they are exposed to different temperature gradients. [0006] For these reasons, th...
