Zusammenfassung:	A method for selectively operating a combustor head end assembly (100) is provided. The combustor head end assembly (100) includes a plurality of bundled tube fuel nozzles (200). The method includes opening a first fuel circuit (PM1) of a plurality of fuel circuits (PM1), (PM2), (PM3). The first fuel circuit (PM1) of the plurality of fuel circuits (PM1), (PM2), (PM3) being fluidly coupled to a first nozzle group (300). The first nozzle group (300) includes one bundled tube fuel nozzle (200) of the plurality of bundled tube fuel nozzles (200). The method further includes adjusting an airflow (26) received by the plurality of bundled tube fuel nozzles (200) in response to opening the first fuel circuit (PM1) of the plurality of fuel circuits (PM1), (PM2), (PM3). The airflow (26) is adjusted based on an emissions output requirement corresponding with the first nozzle group (300). The method also includes firing the first nozzle group (300).
