Problems solved by technology

This in any case creates additional costs and also puts the mechanical resistance of the tiles at risk
Furthermore, the tile holder used to hold the tile against the casing of the combustion chamber limits the space available for coupling the muffler and its positioning becomes difficult, if at all possible

Embodiment Construction

[0046] figure 1 A combustor 1 of a gas turbine is shown (with some parts removed for clarity). The burner 1 comprises an annular combustion chamber 2 extending around an axis A and having an envelope delimited by an annular wall 3 and a heat shield 5 on the inner surface of the annular wall 3 . However, the arrangements described herein are given by way of example only and are not to be considered limiting. In particular, the combustor may be of any type such as a bin or barrel or tube type.

[0047] The heat shield 5 comprises a plurality of first insulating tiles 7 of metal alloy and a plurality of second insulating tiles 8 of refractory material, all arranged in adjacent circumferential rows around the axis A of the combustion chamber 2 . In one embodiment, the insulating tiles 7, 8 may be substantially quadrilateral. However, other shapes are also available.

[0048] At least one of the first insulating shoes 7 selected for the purpose of coupling the silencer is fast...

Abstract

A tile holder for a combustor of a gas turbine, includes: a connector (11) having a tubular body (15) extending along a first axis (X1) and a retaining system (17), configured to secure the tubular body (15) in a seat (18) through a wall (3) and to retain a tile (7; 308) against the wall (3); an acoustic damper (12) having a damping volume (30) and a neck (31) at least in part extending along a second axis (X2); wherein the neck (31) is acoustically coupled to the outside through the tubular body (15) and the first axis (X1) is transverse to the second axis (X2).

Description

[0001] Cross References to Related Applications [0002] This application claims priority from European Patent Application No. 17425059.7 filed May 31, 2017, the disclosure of which is incorporated herein by reference. technical field [0003] The invention relates to a shoe holder for a combustor of a gas turbine. Background technique [0004] As is known, in gas turbine combustors, silencers are used for the purpose of mitigating acoustic pulsations which may occur in certain frequency ranges during operation. Mufflers attenuate acoustic oscillations in the corresponding frequency bands, and when properly tuned, they prevent unwanted vibrations to the benefit of efficiency, performance, and structural integrity. In order to maximize the beneficial effect, the size and location of the mufflers need to be accurately selected and they meet several requirements, eg related to acoustic, thermal and mechanical performance, feasibility and gas turbine efficiency.
