Problems solved by technology

However, in many cases, the seals and / or turbine components can shift, slide, or become disengaged relative to the support structure, thus potentially allowing leakage therein or escape therefrom.
Such leakage and / or escape can reduce the performance and efficiency of the turbine system and can also be detrimental to the system

Abstract

An axial retention device (50) for a turbine (16) is disclosed. The axial retention device includes a latch (52) associated with a mating surface (56, 58) of one of a turbine component (34) and a support structure (32). The latch (52) has an outward bias and includes an axial load surface (70). The axial retention device (50) further includes a pocket defined in a mating surface of the other of the turbine component and the support structure. The pocket (54) is configured to accept the latch therein and includes a mating axial load surface (72). Engagement of the latch and the pocket allows the axial load surface and the mating axial load surface to interact, preventing axial movement of the turbine component with respect to the support structure in at least one direction.

Description

Technical field [0001] The subject matter disclosed herein relates generally to turbine systems, and more specifically to axial retention devices for retaining turbine components in the turbine system. Background technique [0002] Turbine systems are widely used in fields such as power generation. For example, a traditional gas turbine system includes a compressor, combustor, and turbine. During operation of the gas turbine system, various components in the system experience high temperature flows, which can cause component failure. Since higher temperature flows generally result in increased performance, efficiency, and power output of the gas turbine system, components that experience high temperature flows must be cooled to allow the gas turbine system to operate at high temperatures. Therefore, the cooling medium can flow through the gas turbine system to cool various components. [0003] Moreover, in order to obtain the best operation and efficiency of the turbine system, ...
