Abstract

A corona ground element for use in a pre-ionizer of an electrostatic precipitator is provided according to an embodiment of the invention. The corona ground element includes a substantially elongate body including a proximate end and a distal end and first and second projections formed on the proximate end and the distal end. The first and second projections are adapted to retain the corona plate in the electrostatic precipitator.

Claims (38)

1. A corona ground element adapted for use in a pre-ionizer of an electrostatic precipitator, the corona ground element comprising:

a substantially elongate body including a top and a bottom and a proximate end and a distal end; and

first and second projections formed on the proximate end and the distal end between the top and the bottom, with the first and second projections being adapted to retain the corona ground element in the electrostatic precipitator.

2. The corona ground element of claim 1 , wherein the body includes a substantially rectangular cross-sectional shape.

3. The corona ground element of claim 1 , wherein the body includes a substantially circular cross-sectional shape.

4. The corona ground element of claim 1 , wherein the body includes a substantially ovoid cross-sectional shape.

5. The corona ground element of claim 1 , wherein the body includes a substantially teardrop cross-sectional shape.

6. The corona ground element of claim 1 , wherein the body includes a cross-sectional shape including a body and two substantially opposing substantially planar fins.

7. The corona ground element of claim 1 , wherein the body is substantially solid.

8. The corona ground element of claim 1 , wherein the body is substantially hollow.

9. The corona ground element of claim 1 , with the body including a substantially rounded leading edge.

10. The corona ground element of claim 1 , with the body including a substantially rounded trailing edge.

11. A corona ground element adapted for use in a pre-ionizer of an electrostatic precipitator, the corona ground element comprising:

a substantially elongate body including a top and a bottom and a proximate end and a distal end; and

first and second threaded apertures formed on the proximate end and the distal end between the top and the bottom, with the first and second threaded apertures being adapted to retain the corona ground element in the electrostatic precipitator.

12. The corona ground element of claim 11 , wherein the body includes a substantially rectangular cross-sectional shape.

13. The corona ground element of claim 11 , wherein the body includes a substantially circular cross-sectional shape.

14. The corona ground element of claim 11 , wherein the body includes a substantially ovoid cross-sectional shape.

15. The corona ground element of claim 11 , wherein the body includes a substantially teardrop cross-sectional shape.

16. The corona ground element of claim 11 , wherein the body includes a cross-sectional shape including a body and two substantially opposing substantially planar fins.

17. The corona ground element of claim 11 , wherein the body is substantially solid.

18. The corona ground element of claim 11 , wherein the body is substantially hollow.

19. The corona ground element of claim 11 , with the body including a substantially rounded leading edge.

20. The corona ground element of claim 11 , with the body including a substantially rounded trailing edge.

21. A corona ground element adapted for use in a pre-ionizer of an electrostatic precipitator, the corona ground element comprising:

a substantially elongate body including a proximate end and a distal end; and

a substantially aerodynamic cross-sectional shape including a cavity formed in the body, wherein the body is closed and substantially hollow and includes a cross-sectional shape including the body and two substantially opposing substantially planar fins.

22. The corona ground element of claim 21 , with the body including a substantially rounded leading edge.

23. The corona ground element of claim 21 , with the body including a substantially rounded trailing edge.

24. A corona ground element adapted for use in a pre-ionizer of an electrostatic precipitator, the corona ground element comprising:

a substantially elongate body including a proximate end and a distal end, wherein the body includes two substantially opposing substantially planar fins; and

a cavity formed in the body, wherein the body is closed and substantially hollow.

25. The corona ground element of claim 24 , with the body including a substantially rounded leading edge.

26. The corona ground element of claim 24 , with the body including a substantially rounded trailing edge.

27. The corona ground element of claim 24 , wherein the body includes a substantially rectangular cross-sectional shape.

28. The corona ground element of claim 24 , wherein the body includes a substantially circular cross-sectional shape.

29. The corona ground element of claim 24 , wherein the body includes a substantially ovoid cross-sectional shape.

30. The corona ground element of claim 24 , wherein the body includes a substantially teardrop cross-sectional shape.
