Abstract
The invention relates to fuel burners and to combustion equipment for use in gas turbine engines. A more uniform mixture of fuel and air can be obtained in an annular flame tube by ensuring that each fuel injector is maintained in a fixed position in relationship to the annular flame tube. The present invention provides a fuel burner and combustion equipment with means to locate the fuel injector in a fixed position in relationship to the annular flame tube. The fuel burner comprises a fuel feed arm and a fuel injector. The fuel injector is attached to the fuel feed arm, and a fuel passage extends coaxially through the fuel feed arm and supplies fuel to the fuel injector. The fuel from the fuel passage is supplied to a fuel chamber in a pintle positioned within a duct in the fuel injector. The fuel chamber supplies the fuel through a number of fuel passages into the duct. The annular flame tube has a plurality of apertures in the head, and a swirler assembly is positioned coaxially within each aperture, and a fuel injector is positioned coaxially in each of the swirler assemblies. A tongue extends from and is substantially perpendicular to the axis of the fuel injector and the tongue engages with an upstream extending projection of the swirler assembly, to locate the fuel injector relative to the flame tube.
