Abstract
Aspects of the invention relate to a system for attaching a fuel swirler assembly in a turbine engine combustor. According to embodiments of the invention, at least an axial upstream end of the fuel swirler assembly can be attached to a combustor support frame using one or more fasteners, such as bolts. The fuel swirler assembly can include a radial bracket provided on the swirler body to facilitate attachment. The axial downstream end of the fuel swirler assembly can be positioned within an opening defined in a swirler base plate or within an opening in a swirler support plate. Aspects of the invention can reduce the time and cost associated with installation and replacement of fuel swirlers in a combustor while avoiding concerns associated with known welded pin attachment systems.
