Abstract
A fuel manifold is provided for receiving a flow of fuel from a fuel source and delivering the flow of fuel to a rotary fuel slinger. The fuel manifold can include a housing having an end face and defining a cavity for receiving the flow of fuel; at least one exit orifice formed in the housing end face and in fluid communication with the cavity; and a fuel drip guide extending from the end face.
Claims20
A combustion system, comprising;
- a fuel manifold adapted to receive a flow of fuel from a fuel source, the fuel manifold including at least one exit orifice from which the received fuel is discharged;
- a rotary fuel slinger disposed adjacent to, and adapted to receive the flow of fuel from, the fuel manifold and to atomize the received fuel;
- a combustor including at least a forward radial liner and an aft radial liner spaced apart from one another to form a combustion chamber therebetween that receives the atomized fuel from the rotary fuel slinger, the forward and aft radial liners each including a plurality of openings for receiving compressed air into the combustion chamber to mix with the atomized fuel;
- an igniter extending at least partially into the combustion chamber and configured to ignite the atomized fuel and the compressed air mixture;
- and
- a fuel drip guide disposed adjacent the fuel manifold exit orifice.
A fuel manifold for receiving a flow of fuel from a fuel source and delivering the flow of fuel to a rotary fuel slinger, the fuel manifold comprising:
- a housing having an end face and defining a cavity for receiving the flow of fuel;
- at least one exit orifice formed in the housing end face and in fluid communication with the cavity;
- and
- a fuel drip guide extending from the end face.
A method of delivering a flow of fuel to a rotary fuel slinger from a fuel manifold having at least one exit orifice and a fuel drip guide, the method comprising:
- during normal operating conditions, providing the flow of fuel directly from the at least one exit orifice to the rotary fuel slinger;
- and
- during low flow operating conditions, directing the flow of fuel from the at least one exit orifice to the rotary fuel slinger via the fuel drip guide.
