- a shaft 104 extends axially along an engine axis A-A and is coupled to a compressor 106 and a turbine 108.
- the compressor 106 receives air through inlet region 110 and directs the air through alternating rows of rotating and stationary airfoils of decreasing size in order to compress the air as it passes therethrough, thereby increasing the temperature and pressure of the air.
- the compressed air is then directed through one or more combustion systems 112 where fuel and air are mixed together and ignited to form hot combustion gases.
- the hot combustion gases are then directed into the turbine 108 and through alternating rows of rotating and stationary airfoils of increasing size, so as to expand the fluid and convert the energy of the combustion gases into mechanical work to drive the shaft 104.
- the shaft 104 may also be coupled to a shaft of an electrical generator for purposes of generating electricity (not shown).
- FIG. 2 discloses a cross section of a combustor 200 of a gas turbine engine of the prior art.

- the outer face 347 can have an arc-like shape to it, at least along a portion of the outer face, in order for the mounting block 344 to conform to the shape of the inlet ring basket 308.
- the outer face 347 is used to set the radial position of the swirler assembly 332 and its contact with the inlet ring basket 308 to allow tighter dimensional control of the swirler assembly 332 relative to a fuel nozzle.
- the first mounting block 344 also includes a plurality of first holes 348 located in the arc- shaped outer face 347 and oriented generally perpendicular to the longitudinal axis C-C of the premix tube 342, as shown in FIG. 8. [0031]
- the swirler assembly 332 also comprises a second mounting block 346 positioned along the outer wall of the premix tube 342 and spaced an axial distance from the first mounting block 344.
- the second mounting block 346 has a second forward face 346A and an opposing second aft face 346B, where the second aft face 346B is machined to a predetermined size in order to form a specific axial dimension for mounting the swirler assembly 332 in the proper axial location in the combustor.
- the second mounting block 346 includes a relief cut 360 machined into the second aft face 346B.

- a bead of compatible weld material (compatible between the material of premix tube 342 and the mounting blocks 344 and 346) is laid down at the intersection of the mounting block and the premix tube 342.
- a braze joint will help form a more complete joint as the entire surface of the mounting block in contact with the premix tube 342 is joined to the premix tube 342.
- a weld joint only secures the mounting block to the premix tube 342 at the edges where the mounting block contacts the premix tube.
- the exact size, spacing and quantity of holes in the first mounting block 344 and the second mounting block 346 can vary and depends on a variety of factors such as combustor geometry, size of the swirler assemblies 332, and mechanical and thermal loading on the swirler assemblies 332.

- the second hole 356 is generally parallel to axis C-C.
- the swirler assembly 332 is designed to be easily removable from a combustor to better facilitate maintenance and repair. Therefore, a plurality of removable fasteners 350 and 358 are utilized to secure the swirler assembly 332 in the combustor.
- the removable fasteners such as bolts, engage a corresponding thread pattern in the plurality of first holes 348 and one or more second holes 356.
- a thread pattern is but one way of securing the removable fasteners.
- the one or more second holes 356 could be through holes (i.e. not threaded) and utilize a nut adjacent to surface 346 A.
- a bolt/stud could be welded/installed in lieu of hole 356 with a nut then placed on the surface of the dome plate 334.
- the swirler assemblies 332 are positioned so as to be in fluid communication with adjacent tubes 352, also referred to as hoovers, which pass the flow of fuel and air from the swirler assembly 332 to the mixing zone of the combustion liner 300. That is, the swirler assemblies 332 are positioned so as to be adjacent to or slightly engaged in the tubes 352. In order to ensure that the swirler assemblies 332 are in the proper radial position in the combustion liner and form a radial clearance with the tubes 352, a plurality of stand offs 354 are located about the outer surface of each of the premix tubes 342, adjacent the outlet end 342B.
- the swirler assemblies 332 are removably secured to the combustor through a plurality of fasteners 350 and 358, such as bolts or other means.
