Method of disgorging flames from a two stream tangential entry nozzle

摘要

A method of reducing the tendency of the combustion flame to stabilize within the mixing zone of a tangential entry nozzle is disclosed which comprises mixing fuel and air in a mixing zone within a fuel nozzle assembly, thereby producing a first fuel/air mixture which is isolated from the combustion products by maintaining sufficiently high axial velocities throughout the mixing zone and using a combination of a second internal passageway within a centerbody (either fueled or unfueled) and the surfaces of the combustor inlet port.
