PLASMA BURNER WORKING WITH GAS MIXTURES |
摘要 |
The present invention relates to a plasma burner for metallurgical furnaces which is operated with gaseous mixtures, wherein an addition gas is fed to the plasma burner via a ring conduit into the inside of the burner. The gas conduction pipes on the addition-gas outlet are arranged at a predetermined angle to the longitudinal axis of the burner, 35 DEG to 45 DEG . The point of intersection between plasma arc and addition gas is 25 to 45 mm in front of the rod-shaped cathode. In order to increase the output with constant arc current and without chemical reaction with as molten material, hydrogen or nitrogen is used as addition gas; and when a chemical reaction is desired, oxygen or oxygen-containing gas mixtures are used. |
