摘要： A thermal plasma torch and method are disclosed. The plasma torch abatement apparatus for treatment of an effluent stream from a processing tool comprises: an anode and a cathode arranged to generate, in a plasma discharge region, a plasma stream from a plasma gas; and an effluent stream conduit arranged to convey the effluent stream to flow coaxially with the plasma stream. In this way, rather than intersecting the effluent stream, the plasma stream instead flows with the effluent stream. This helps to prolong the reaction time of the effluent stream in the plasma phase and reduces the risk of any of the effluent stream bypassing the plasma stream completely. This significantly improves the abatement effectiveness of the plasma torch. (Figure 1)

Improved alignment ensures an adequate flow of coolant along an interior surface of the electrode. In one aspect, an elongated body of the coolant tube has a surface adapted to mate with the electrode. In another aspect, an elongated body of the electrode has a surface adapted to mate with the coolant tube. The surfaces of the tube and electrode may, for example, be flanges, tapered surfaces, contours, or steps.
