  • Liquid fuel injector system
    Patent number: 6178751
    Abstract: The liquid fuel injector includes continuous air assist with both the liquid fuel injector tube and the surrounding air assist tube constrained or reduced in diameter at the discharge ends thereof. The associated gas turbine engine compressor provides combustion air to the combustor and also air for continuous air assist with a separate air pump. The air assist air may be cooled in a heat exchanger either before or after the separate air pump. The liquid fuel injector may be mounted within an annular air blast tube and directed tangentially at the inner wall of the combustor. A solenoid valve controlled purge line, together with solenoid valves in the liquid fuel and air assist lines can be utilized to purge any liquid fuel in the liquid fuel injector and manifold upon shutdown of the combustor. The liquid fuel injector can also be insulated and liquid fuel can be used to cool the fuel injector.
    Type: Grant
