Abstract:
An embodiment of a torch ignitor system for a combustor of a gas turbine engine includes a torch ignitor, the torch ignitor include a combustion chamber oriented about a torch axis, the combustion chamber having axially upstream and downstream ends defining a flow direction through the combustion chamber, along the axis. The torch ignitor further includes a tip at a downstream end of the elbow for issuing the injection of combustion products. An embodiment of a method includes initiating combustion in a combustion chamber of a torch ignitor to produce an ignition jet flame extending along an ignition jet flame axis, and igniting a fuel/air mixture in a gas turbine combustor by issuing a respective spray cone of the fuel/air mixture from a respective fuel injectors in a plurality of fuel injectors, wherein the ignition jet flame axis intersects a plurality of the spray cones.
