Abstract
A liquid fuel injector nozzle for a gas turbine combustor delivers liquid fuel to the combustion chamber in discrete jets. The liquid fuel injector nozzle includes a fuel passage that terminates with a swirl pilot including a plurality of swirl slots for imparting swirl to the liquid fuel. The spin chamber disposed downstream of the swirl pilot is configured to deliver the liquid fuel to the discharge orifice in discrete jets. The discrete fuel streams are concentrated in a fashion to minimize atomization until the fuel adequately penetrates the premixer air stream, resulting in burning properties that lead to increased efficiency, lower emissions, greater flame stability and improved pattern factor when compared to hollow cone spray pattern injection techniques.
