Abstract: Known wet electrostatic precipitators are large and inefficient. The present invention enables the production of smaller, more efficient and long lasting wet electrostatic precipitators by the addition of a central bore in the inner electrode through which a first purge flow is passed and directed into the precipitator chamber, perpendicular to the direction of flow of the gas to be treated through the chamber to urge the particulate into the water curtain. A second, larger, cleaning purge flow is also provided to disturb the water curtain such that it cleans the inner electrode of any deposited particulate.

Abstract: An apparatus for treating a gas stream includes a plasma abatement device that has a reaction chamber and a plasma torch for generating a plasma stream for injection into the chamber for treating the gas stream. A first inlet conveys a gas stream into the plasma abatement device for treatment, and a second inlet, in a normal condition of the apparatus, is in flow communication with a source of reagent for conveying a reagent into the plasma device for improving the efficiency of the treatment. In a back-up condition of the apparatus, the second inlet is in flow communication with a gas stream source for conveying a gas stream into the device for treatment.

Abstract: To lengthen the service period on DC plasma abatement devices a modified DC plasma torch is provided with an electrically conductive cathode and an electrically conductive anode spaced apart from one another to form a gap therebetween; a metal swirl bush at least partially located within the gap and comprising a channel adapted to permit, in use, a gas to flow through the gap; and a ceramic element interposed between any one or more of: the cathode and the swirl bush; and the anode and the swirl bush.
