A nozzle for an abatement apparatus and a method are disclosed. The nozzle is for abatement apparatus operable to treat an effluent stream from a processing tool, the nozzle comprises: a nozzle body defining a nozzle inlet operable to receive the effluent stream, a nozzle outlet, and a conduit extending between the nozzle inlet and the nozzle outlet and operable to convey the effluent stream in a direction of flow from the nozzle inlet to the nozzle outlet; and an effluent stream rotator configured to impart a rotational component to the effluent stream to rotate the effluent stream around the direction of flow. In this way, the effluent stream is rotated as it passes through the nozzle body. The destruction rate efficiency achieved by an abatement apparatus when receiving such rotating effluent streams has been found to be significantly improved compared to non-rotating effluent streams.
