Abstract
A method for operating a gas turbine engine including a combustor assembly includes channeling a first fluid through a plurality of first nozzles into the combustor and igniting the first fluid downstream from the first nozzles. The method also includes increasing the operating speed of the engine and attaining a first predetermined percentage of a baseload by channeling the first fluid only through the first nozzles and then channeling a second fluid through a second nozzle into the combustor. The method also includes igniting the second fluid within the combustor downstream from the second nozzle. The method further includes channeling the second fluid to the first nozzles when the engine attains a second predetermined percentage of the baseload. The second predetermined percentage of the baseload is greater than the first predetermined percentage of the baseload. The method also includes terminating a flow of the first fluid through the first nozzles.
