Gas turbine fuel injector for lower heating capacity fuels
A fuel injector for a gas turbine engine includes a stem extending along a longitudinal axis from a proximal end to a distal end. The stem includes one or more fuel tubes configured to deliver a fuel toward the distal end of the stem, and a pilot assembly coupled to the distal end of the stem. The p...

| description | A fuel injector for a gas turbine engine includes a stem extending along a longitudinal axis from a proximal end to a distal end. The stem includes one or more fuel tubes configured to deliver a fuel toward the distal end of the stem, and a pilot assembly coupled to the distal end of the stem. The pilot assembly includes one or more components configured to inject fuel into a combustor of the engine. The fuel injector also includes a substantially tubular premix barrel extending along the longitudinal axis from a first end to a second end. The premix barrel is circumferentially disposed about the stem and configured to couple with the combustor at the second end. The fuel injector also includes an annular premix duct formed between the premix barrel and the stem. The premix duct includes an air inlet port at the first end, and a plurality of first orifices located downstream of the air inlet port. The first orifices are configured to inject fuel from the fuel tube into the premix duct. The premix duct also includes a plurality of second orifices located downstream of the first orifices. The second orifices are configured to inject fuel from the fuel tube into the premix duct. |
