Combustion liner guide stop and method for assembling a combustor

Abstract

A combustor for a gas turbine including a casing, a flow sleeve at least partially disposed within the casing, a combustion liner at least partially disposed within the flow sleeve, a liner stop feature extending from the combustion liner, and a liner guide stop including a first end separated from a second end, the second end configured to be at least partially engaged with the liner stop feature, wherein the liner guide stop extends through the casing and the flow sleeve.

Description

technical field [0001] The present invention relates generally to combustor liner guide baffles for gas turbine combustors, and more particularly to combustion liner guide baffles inserted through combustor casings and methods for assembling said combustors. Background technique [0002] A gas turbine generally includes a compressor section, a combustor section, and a turbine section. The compressor section pressurizes the air flowing into the turbine. Pressurized air discharged from the compressor section flows into the combustor section, which is typically characterized by a plurality of combustors arranged in an annular array about the axis of the gas turbine. Each of the plurality of combustors includes a combustor liner that defines a combustor's combustion chamber. Thus, the air entering each combustor is mixed with fuel and burned within the combustion chamber lining. Hot combustion gases flow from the combustor liner through the transition piece into the turbine s...

AI Technical Summary

Problems solved by technology

The combustor liner and / or duct sleeve must be removed and workers must either machine the damaged part on-site or send the part off-site for repair, resulting in costly repairs and extended downtime
