Abstract:
One embodiment includes a fuel injector. The fuel injector assembly comprises a conduit for conveying fuel from a fuel inlet to a nozzle. The conduit is located in a support, with the conduit, the nozzle, and the support being a single unitary piece. A thermally compliant feature is located at the nozzle which allows the fuel injector to adjust for differential thermal expansion.
Abstract:
In various embodiments, a fuel injector (220) may comprise a fuel nozzle (230) and a pilot stage (252). The fuel nozzle (230) may define a main fuel channel (231), a secondary fuel channel (233), a simplex fuel channel (235) and a heat shield area (232). The main fuel channel (231) may be disposed about at least a portion of the simplex fuel channel (235). The secondary fuel channel (233) may be disposed about at least a portion of the simplex fuel channel (235). The heat shield area (232) may be configured to separate and protect the fuel channels from a heat load to prevent fuel coking. The pilot stage (252) may be operatively coupled to the fuel nozzle (230) and may be configured to receive fuel from the secondary fuel channel (233) or the simplex fuel channel (235). The main stage (242) may be operatively coupled to the fuel nozzle (230). The main stage (242) may be configured to receive fuel from the main fuel channel (231).
Abstract:
A system for dispersing a catalyst in a fuel includes a first reservoir (12) containing the fuel, and a second reservoir (24) including an agitator (26) and containing a quantity of the catalyst suspended in the fuel. The system also includes a first conduit (14) extending from the first reservoir, a second conduit (28) extending from the second reservoir, and a mixing nozzle (16) connected to the first conduit and the second conduit. The mixing nozzle (16) includes a first meter (34) positioned within the first conduit, a second meter (32) positioned within the second conduit, a valve (30) positioned upstream from the second meter within the second conduit, a junction (36) in flow communication with the first conduit and the second conduit, a mixer (38) downstream from the junction, a sensor (40) positioned between the mixer and an outlet; and a controller (42) connected to the valve and the first and second meters, the controller receiving feedback from the sensor.
Abstract:
An assembly is provided for a turbine engine. The assembly includes a fuel injector and a fuel vaporizer. A nozzle of the fuel injector is adapted to direct fuel to impinge against the fuel vaporizer. The fuel vaporizer is adapted to substantially vaporize the impinging fuel.
