<p>A method of control of a plasma stream formed by at least two plasma-forming gas, in which the gas jets are acted on by passing electric currents therethrough and superposing a magnetic field on each jet. One of the physical parameters of the total plasma stream is monitored and, if it has changed, the magnitude of the force acting on at least one of the converging jets is varied until a required result is obtained. This method is effected by using a plasma apparatus including at least two plasma burners (1) arranged at an angle to each other and connected to a power supply (7) and to a plasma-forming gas source (8). Each burner (1) is provided with an open magnetic circuit (4) with a solenoid (5) connected to a power supply (6). The apparatus is provided with a unit (9) for recording the physical parameters of the plasma stream (2). The unit (9) for recording the physical parameters is connected to a processing unit (10) whose outputs are connected to the power supplies (6) and (7) and to the plasma-forming gas source (8). The burners (1) are provided with a drive (3) which is also connected to the processing unit (10).</p> |
