An apparatus for remediating a contaminated fluent material, such as a gas, utilizes a pulsed corona discharge. The apparatus includes a reactor section and a power supply section. The reactor section has a plurality of first electrodes electrically interconnected to a header plate and a plurality of second electrodes concentrically disposed about each first electrode and electrically interconnected to a reactor plate. The electrical contact between the header plate and the power supply is by a compression spring. When fluent material is flowing within channels defined by the second electrodes and a high voltage pulse is applied to the header plate, a stream of high energy electrons flows between the first electrodes and the second electrodes forming corona discharges effective to destroy polluting compounds contained in the contaminated fluent material.

A geometry for a spark switch includes an inner electrode surrounded by an outer electrode. The placement of the inner electrode within the outer electrode substantially increases the exposed overlapping surface area of the electrodes. The increase in surface area of the electrodes results in a proportional increase in the operational life of the switch. The design of the spark switch also causes the outer electrode to shield a surrounding insulation layer against debris that would otherwise contaminate an insulation layer.
