1. A particle separator for removing particles from a gaseous stream, the particle separator comprising: a separator body having a centerline axis and a peripheral wall defining a separation chamber; a fluid inlet in fluid communication with the separation chamber; a particle outlet in fluid communication with the separation chamber; a fluid outlet in fluid communication with the separation chamber; and a vortex tube having a hollow interior and a peripheral wall extending along the centerline axis and fluidly coupling the fluid outlet and the separation chamber. 2. The particle separator of claim 1 , wherein the peripheral wall of the vortex tube further comprises a plurality of angled outlet apertures fluidly coupled between the hollow interior and the separation chamber.3. The particle separator of claim 2 , wherein the angled outlet apertures are aligned in the direction opposing the inlet flow.
4. The particle separator of claim 1 , wherein the vortex tube a cross-sectional shape which correlates to the shape of the separation chamber.5. The particle separator of claim 1 , wherein the vortex tube tapers from a first diameter at one end of the separator body to a second diameter smaller than the first diameter at the other end of the separator body.6. The particle separator of claim 1 , wherein the vortex tube is unitarily formed with the separator body.7. The particle separator of claim 1 , wherein the vortex tube has a free end with a radially outwardly projecting lip.8. The particle separator of claim 7 , wherein the peripheral wall of the vortex tube further comprises a plurality of tangential inlet apertures fluidly coupled between the hollow interior and the separation chamber.9. The particle separator of claim 7 , wherein the vortex tube is unitarily formed with the separator body.
10. The particle separator of claim 1 , wherein the vortex tube has a free end with a plurality of apertures for directing a portion of a gaseous stream axially and radially outwardly from the free end.11. The particle separator of claim 10 , wherein the peripheral wall of the vortex tube further comprises a plurality of tangential inlet apertures fluidly coupled between the hollow interior and the separation chamber.12. The particle separator of claim 10 , wherein the vortex tube is unitarily formed with the separator body.
13. A particle separator for removing particles from a gaseous stream, the particle separator comprising: a separator body having a centerline axis and a peripheral wall defining a separation chamber; a fluid inlet in fluid communication with the separation chamber; a particle outlet in fluid communication with the separation chamber; a fluid outlet in fluid communication with the separation chamber; and a vortex tube having a hollow interior and a peripheral wall extending along the centerline axis; and a hollow annular inlet plenum fluidly coupling the fluid inlet and the separation chamber; wherein the peripheral wall of the vortex tube further comprises a plurality of tangential outlet apertures; and wherein the tangential inlet apertures are aligned in the direction of the inlet flow. 14. The particle separator of claim 13 , wherein the vortex tube is unitarily formed with the separator body.15. The particle separator of claim 13 , wherein the separation chamber has an axisymmetric shape.16. The particle separator of claim 13 , wherein at least a portion of the separation chamber has a conical shape.17. The particle separator of claim 13 , wherein the tangential inlet apertures are approximately equally circumferentially spaced around the peripheral wall.18. The particle separator of claim 13 , wherein the tangential inlet apertures are unitarily formed into the peripheral wall of the vortex tube.
19. A particle separator for removing particles from a gaseous stream, the particle separator comprising: a separator body having a centerline axis and a peripheral wall defining a separation chamber; a fluid inlet in fluid communication with the separation chamber; a particle outlet in fluid communication with the separation chamber; a fluid outlet in fluid communication with the separation chamber; and a plurality of angled inlet apertures fluidly coupled between the fluid inlet and the separation chamber. 20. The particle separator of claim 19 , wherein the separation chamber has an axisymmetric shape.
