Abstract

An apparatus is provided and includes an inlet, including a peripheral wall formed to define a pathway along which gaseous, fluidic and particulate matter flow and two or more nets sequentially disposed in the pathway, the two or more nets being suspended on the peripheral wall with substantially no clearance between each of the two or more nets and the peripheral wall and held sufficiently loosely to permit relative movement of each of the two or more nets such that an effective pore size of the two or more nets is variable over time to encourage fluidic condensation at the two or more nets and to permit a relatively substantial portion of the gaseous and particulate matter to continue to flow.

Claims (46)

1. An apparatus, comprising:

an inlet, including a peripheral wall formed to define a pathway along which gaseous, fluidic and particulate matter flow; and

two or more nets sequentially disposed in the pathway, the two or more nets being suspended on the peripheral wall with substantially no clearance between each of the two or more nets and the peripheral wall and held sufficiently loosely to permit relative movement of each of the two or more nets such that an effective pore size of the two or more nets is variable over time to encourage fluidic condensation at the two or more nets and to permit a relatively substantial portion of the gaseous and particulate matter to continue to flow.

2. The apparatus according to claim 1 , wherein the apparatus comprises a gas turbine.

3. The apparatus according to claim 1 , wherein the two or more nets each have pore sizes of less than about 1 mm.

4. The apparatus according to claim 1 , wherein the two or more nets comprise a Raschel Weave.

5. The apparatus according to claim 1 , wherein the two or more nets comprise a shade netting with shade performance of about 35% to about 80%.

6. The apparatus according to claim 1 , wherein the relative movement is more than about 5 cm.

7. The apparatus according to claim 1 , wherein the relative movement is up to half a perpendicular length of either of the two or more nets.

8. The apparatus according to claim 1 , wherein a substantially entire periphery of each of the two or more nets is connected to the peripheral wall.

9. The apparatus according to claim 1 , wherein the two or more nets each have a substantially similar tension.

10. The apparatus according to claim 1 , wherein the two or more nets each have a unique tension.

11. The apparatus according to claim 1 , wherein the fluidic condensation occurs at least at one of the two or more nets.

12. The apparatus according to claim 1 , wherein the two or more nets are oriented substantially perpendicularly with respect to a predominant direction of gaseous, fluidic and particulate matter flow along the pathway.

13. The apparatus according to claim 1 , wherein the two or more nets are disposed sufficiently vertically whereby gravitational drainage of condensed fluid is encouraged.

14. The apparatus according to claim 1 , wherein the two or more nets are disposed in parallel with one another.

15. The apparatus according to claim 1 , wherein the two or more nets are disposed transversely with respect to one another.

16. An apparatus, comprising:

an inlet, including a peripheral wall formed to define a pathway along which gaseous, fluidic and particulate matter flow;

two or more nets sequentially disposed in the pathway;

a suspension coupled to the peripheral wall and the two or more nets to suspend the two or more nets on the peripheral wall with substantially no clearance between each of the two or more nets and the peripheral wall and with the two or more nets held sufficiently loosely to permit relative movement of each of the two or more nets such that an effective pore size of the two or more nets is variable over time to encourage fluidic condensation at the two or more nets and to permit a relatively substantial portion of the gaseous and particulate matter to continue to flow; and

a drainage system into which the condensed fluid drains off of the two or more nets.

17. The apparatus according to claim 16 , wherein the suspension is coupled to a substantial entirety of a periphery of each of the two or more nets.

18. The apparatus according to claim 16 , wherein the suspension comprises a single suspension for the two or more nets.

19. The apparatus according to claim 16 , wherein the suspension comprises a separate sub-suspension for each of the two or more nets.

20. The apparatus according to claim 19 , wherein each sub-suspension comprises:

a pocket neck extrusion, to which an entire periphery of one of the two or more nets is attached;

an inner frame to define a pocket to retain the pocket neck extrusion; and

an outer frame, attached to the peripheral wall, in which the inner frame is supported.

21. The apparatus according to claim 20 , wherein the entire periphery is sewn to the pocket neck extrusion.

22. The apparatus according to claim 20 , wherein the inner frame comprises:

a frame structure defining an interior; and

a member coupled to the frame structure to define the pocket.

23. The apparatus according to claim 22 , wherein the pocket neck extrusion is received within the interior and, once received, oriented for disposition in the pocket.

24. The apparatus according to claim 20 , wherein the outer frame comprises:

a base attachable to the peripheral wall;

sidewalls extending from opposing ends of the base; and

a notch positioned along a mid-section of one of the sidewalls.

25. The apparatus according to claim 24 , wherein the inner frame is insertible into the outer frame between the sidewalls and between the base and the notch.

26. The apparatus according to claim 20 , wherein no combination of axial or radial forces applied by the one of the two or more nets removes the pocket neck extrusion from the pocket or the inner frame from the outer frame.

27. An apparatus, comprising:

an inlet, including a peripheral wall formed to define a pathway along which gaseous, fluidic and particulate matter flow;

a first net disposed in the pathway;

a second net disposed in the pathway downstream from the first net;

a suspension coupled to the peripheral wall and the first and second nets to suspend the first and second nets on the peripheral wall with substantially no clearance between each of the first and second nets and the peripheral wall and with the first and second nets held sufficiently loosely to permit relative movement of each of the first and second nets such that an effective pore size of the first and second nets is variable over time to encourage fluidic condensation and to permit a relatively substantial portion of the gaseous and particulate matter to continue to flow; and

a drainage system into which the condensed fluid drains off of the first and second nets.
