ABSTRACT:
A pre-ionizer for use with an electrostatic precipitator is provided according to an embodiment of the invention. The pre-ionizer includes two or more corona ground elements arranged in a substantially parallel orientation. A corona ground element of the two or more corona ground elements 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 retain the corona ground element in the electrostatic precipitator. The pre-ionizer further includes one or more corona charge elements positioned between two adjacent corona ground elements of the two or more corona ground elements. When a high voltage electrical field is placed across the two or more corona ground elements and the one or more corona charge elements, the pre-ionizer at least partially ionizes airflow through the pre-ionizer.
