DEVICE AND METHOD FOR SPRAYING NATURAL GAS AND/OR OXYGEN |
摘要 |
<p>The invention relates to a device for spraying fuel and/or oxygen into a metallurgic melting furnace, especially an arc furnace. Said device comprises supply conduits for fuel (2), oxygen (4) and cooling water (20), a diagonally arranged bore that is used as an outlet for fuel (3) and a delivery nozzle (12) with diagonally arranged openings for oxygen. The oxygen that streams in via the supply conduit opens the delivery nozzle by exerting pressure onto a plunger and by moving an axial piston rod with a lock component in the direction of the relief opening. The bore and the diagonally arranged openings are thus freed. The invention also relates to a method for the post combustion of incompletely burned products in a metallurgic melting furnace. The pulsed current is adjusted in such a way that it is smaller than 45N/MW when fuel/oxygen is/are used and/or is smaller than 90N/MW when only oxygen is used.</p> |
