Abstract:
A plasma apparatus comprising:a first plasma burner that generates a first plasma jet; a second plasma burner that generates a second plasma jet, the second plasma jet being directed to join with the first plasma jet in a combined stream; a measurement, processing and control system to separately measure a characteristic of the first plasma jet and a characteristic of the second plasma jet and adjust the first and second plasma jets so that the measured characteristics match characteristics that were predetermined to provide the combined stream with desired properties; wherein said system comprises a first camera which has a field of view that includes the first and second plasma jets; and the first camera is positioned such that throughout an expected range of motion of the first and second plasma jets, an image of the first jet remains on one side of an image of a reference point in the field of view and an image of the second jet remains on an opposite side of the image of the reference point in the field of view.
