Claim 6:
7. A method, comprising:
receiving fuel into an auxiliary combustion chamber of a first igniter stage of a turbine combustor assembly;
mixing air incoming into the auxiliary combustion chamber with the fuel to provide a first air and fuel mixture;
igniting the first air and fuel mixture in the auxiliary combustion chamber;
receiving additional fuel into an auxiliary fuel outlet manifold of a second igniter stage arranged proximal to an outlet of the auxiliary combustion chamber;
providing, by a circumferential pattern of fuel openings defined by the auxiliary fuel outlet manifold, additional igniter fuel to the ignited first air and fuel mixture proximal the outlet;
igniting, by the ignited first air and fuel mixture, the additional igniter fuel provided by the auxiliary fuel outlet manifold to provide a combusting air and fuel mixture; and
igniting a primary air and fuel mixture, in a primary combustion chamber of the turbine combustor assembly, with the combusting air and fuel mixture.
