Method for obtaining metal from a blast furnace or cupola furnace |
| abstract |
A high-speed jet of liquid oxygen (21) with a speed higher than 100 meters per second is delivered into the tuyeres of a blast furnace or cupola furnace together with pulverised carbon. The jet reaches the opposite wall of the cavity (9) formet at the outlet of the tuyere (6) in the mass of material contained in the shaft. Supplying oxygen to the bottom of the cavity improves the burning of the remaining coal, whereby higher injection levels may be achieved. The shape of the cavity may also be altered, and, in particular, faster reactions may be achieved in the axial region of the shaft. |
