Embodiment Construction

[0018] Referring now to the drawings, wherein like numerals refer to like elements throughout the several views. figure 1 is a schematic illustration of a gas turbine engine 10 that may be used herein. The gas turbine engine 10 may include a compressor 15 . Compressor 15 compresses an incoming air stream 20 . Compressor 15 delivers compressed air flow 20 to a plurality of combustor cans 25 . The combustor can 25 mixes the compressed air flow 20 with the pressurized fuel flow 30 and ignites the mixture, thereby producing a hot combustion gas flow 35 . Although only a single combustor can 25 is shown, gas turbine engine 10 may include any number of combustor cans 25 arranged in a circumferential array or the like. The hot combustion gas flow 35 is then passed to a turbine 40 . The flow of hot combustion gases 35 drives a turbine 40 to produce mechanical work. The mechanical work produced in turbine 40 drives compressor 15 via shaft 45 and drives an external load 50 such as ...

Abstract

The title of the invention is methods and devices for assembling / removing a fire pipe. The present application provides a cross fire tube installation / removal apparatus (100) for use with a combustor(25) of a gas turbine engine (10). The cross fire tube installation / removal apparatus (100) includes a cross fire tube assembly (110) having a sleeve (120, 130) with a tube groove (170, 180) therein and a cross fire tube tool (300) having a spring (390) with a spring flange (440). The spring flange (340) is sized to engage the tube groove (170, 180).

Description

technical field [0001] This application and the resulting patent relate generally to gas turbine engines, and more particularly to improved methods and apparatus for installing and removing gas turbine combustor crossfire tubes in a quick, safe and efficient manner. Background technique [0002] Adjacent combustors of gas turbine engines are usually connected by cross-fire tubes. Specifically, crossfire tubes may extend through the liner, flow sleeve, and casing of adjacent combustors to allow combustion in one combustor to propagate to adjacent combustors and ensure The chambers are ignited substantially simultaneously and the pressures are equalized. Generally, crossfire tubes need to be removed prior to burner removal etc. However, the assembly and / or location of cross-fire tubes may have one or more disadvantages. For example, current methods of installation and removal can be complicated and can result in damage to the crossfire tube and associated components. Cont...
