Abstract

An apparatus is provided for a turbine engine. This turbine engine apparatus includes a monolithic body. The monolithic body includes a splash plate and a fuel nozzle. The splash plate includes a splash plate surface. The fuel nozzle includes a nozzle orifice. The fuel nozzle is configured to direct fuel out of the nozzle orifice to impinge against the splash plate surface.

First claim

What is claimed is:

1. An apparatus for a turbine engine, comprising:
a fuel vaporizer comprising a vaporizer centerline and a fluid passage extending along the vaporizer centerline through the fuel vaporizer; and
a monolithic body including a splash plate, a support member and a fuel nozzle, the splash plate including a splash plate surface, the support member connecting and extending between the splash plate and the fuel nozzle, the fuel nozzle including a nozzle orifice, the fuel nozzle configured to direct fuel out of the nozzle orifice to impinge against the splash plate surface, the splash plate surface angularly offset from the vaporizer centerline and configured to direct at least some of the fuel against the fuel vaporizer, the fuel nozzle projecting into a flow passage, the support member is upstream of the nozzle orifice relative to a fluid flow within the flow passage, and a width of the splash plate surface greater than a width of the nozzle orifice.

2. The apparatus of claim 1 , wherein
the fuel nozzle is configured to direct the fuel out of the nozzle orifice as a fuel jet; and
the splash plate is configured to redirect the fuel jet into a radiant pattern of fuel.

3. The apparatus of claim 1 , wherein the splash plate is spaced from and overlaps the nozzle orifice.

4. The apparatus of claim 1 , wherein the splash plate surface comprises a planar splash plate surface.

5. The apparatus of claim 1 , wherein
the fuel nozzle is configured to direct the fuel out of the nozzle orifice along a trajectory to impinge against the splash plate surface; and
the splash plate surface is angularly offset from the trajectory by an acute angle.

6. The apparatus of claim 5 , wherein the acute angle is between sixty degrees and eighty degrees.

7. The apparatus of claim 5 , wherein the acute angle is between thirty-five degrees and fifty-five degrees.

8. The apparatus of claim 1 , further comprising a second support member connecting and extending between the splash plate and the fuel nozzle.

9. The apparatus of claim 1 , wherein
the fuel nozzle includes a nozzle tube that has and extends along a longitudinal centerline; and
the nozzle orifice is coaxial with the longitudinal centerline.

10. The apparatus of claim 1 , wherein
the monolithic body further includes a turbine engine case; and
the fuel nozzle projects out from the turbine engine case towards the fuel vaporizer.
