Abstract: Anti-Coke Fuel Nozzle Coke hereinbefore known to form in the secondary passage of a dual orifice fuel nozzle for the combustor of a turbine type power plant is prevented from forming by imposing increased air pressure in the secondary passage during its inoperative mode and when the primary fuel passage is in the operative mode, without relying on purging or requiring an external air source.

Abstract: Fuel Nozzle For Gas Turbine Engine A fuel nozzle designed to reduce pollutant emissions and minimize the buildup of coke in the secondary fuel passage of a dual orifice fuel nozzle for the combustor of a gas turbine engine sizes the orifices and passages of the air and fuel so as to increase the pressure in the secondary passage during its inoperative mode and when the primary fuel passage is in the operative mode and having the air and fuel issuing from both the primary and secondary orifices swirl in the same direction.

Abstract: Airblast Fuel Injector A fuel injector assembly for a gas turbine combustor projects a hollow conical spray of fuel. A plurality of discrete surrounding air nozzles 42 project air directly toward the axis 46 of the injector at an angle of 15 degrees, establishing a fuel rich external recirculation zone 52.

Abstract: Fuel Nozzle With Water Injection For Gas Turbine Engines A pressure atomizing fuel nozzle of the type that has a primary and secondary fuel system for a gas turbine engine and includes air swirl means and water injection is designed so that the water laden airstream is swirling in the same direction as both the fuels egressing from the primary fuel system and the secondary fuel system.
