Abstract
Coking of the hot external face of fuel nozzles operating in the combustor of a gas turbine engine is reduced by controlling air discharging from the nozzle face in a manner to provide a recirculation zone spaced away from the nozzle face a distance effective to substantially reduce coking and yet maintain a stable flame front in the combustor.
