| 摘要 |
The invention relates to a method and a means for facilitating the replacement of plasma generators and for minimizing the heat losses during installation of a plasma generator in a shaft furnace, particularly for plasma generators of the type comprising cylindrical electrodes between which an electric arc is generated, the bases of the arc being caused to rotate by means of electric field coils arranged around said electrodes. To achieve this at least the field coil (7) surrounding the electrode nearest to the nose (12) of the plasma generator, together with its connections for coolant and electricity, is permanently secured in the wall (1) of the shaft furnace in conjunction with the opening (6) for insertion of the plasma generator (11) into the shaft furnace. |
