Abstract
1,051,952. Electric heating. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Oct. 22, 1963 [Oct. 24, 1962], No. 41671/63. Heading H5H. A plasma flame generator having an arc 9 in the flow path of a main fluid stream 7 and having provision for introducing fluids or powders over passage 5 is arranged to prevent erosion of the downstream arc-root by the material introduced through passage 5. For this purpose the root is positioned out of the direct flow from the passage 5 and before mixing of the two fluid streams. A magnetic field is established across the arc and produces a force on it opposite to that due to the stream 8. According to the strength of the field the arc-root is positioned opposite or adjacent the passage 8 but the field-strength is always sufficient to prevent the arc being blown unduly to one side. In a specific example, the electrode 1 is a watercooled cylinder of copper, the electrode 4 is of tungsten, and argon flows from aperture 7 at 20 litres a minute; the discharge is of 180 amperes, and water mist is supplied at 5 at five grammes per minute; a magnetic field H of 300-500 gauss is said to be sufficient.
