Abstract

In systems and methods (300) for operating an engine (10, 102, 104), the engine (10, 102, 104) is operated at low power by supplying fuel to a combustor (14) through a first set of fuel nozzles (201) of at least one first manifold (211) and without supplying fuel to the combustor (14) through a second set of fuel nozzles (202) of at least one second manifold (212). An amount of fuel (250) to at least in part fill the at least one second manifold (212) to impede fuel coking of the second set of fuel nozzles (202) is determined. The amount of fuel (250) is periodically supplied to the at least one second manifold (212).
