Abstract

A pre-ionizer (330) for use with an electrostatic precipitator (300) is provided according to an embodiment of the invention. The pre-ionizer (330) includes two or more corona ground elements (334) arranged in a substantially parallel orientation. A corona ground element (334) of the two or more corona ground elements (334) includes a substantially elongate body (1401) including a proximate end (1402) and a distal end (1403) and first and second projections (607) formed on the proximate end (1402) and the distal end (1403). The first and second projections (607) retain the corona ground element (334) in the electrostatic precipitator (300). The pre-ionizer (330) further includes one or more corona charge elements (336) positioned between two adjacent corona ground elements (334) of the two or more corona ground elements (334). When a high voltage electrical field is placed across the two or more corona ground elements (334) and the one or more corona charge elements (336), the pre-ionizer (330) at least partially ionizes airflow through the pre-ionizer (330).
