| Abstract: |
| Burning decarbonization of stone coal vanadium ore by circulating fluidized bed was tested. Burning tests of single stone coal were conducted upon bed temperature reaching 850~880 ℃ by burning of bituminous coal. Burning parameters were monitored and recorded. Waste gas, bottom slag, and fly ash were sampled and analyzed. The results show that burning conditions are stable, and circulation circuit is expedite. Combustion efficiency is 74.16%. Carbon content in bottom slag and fly ash is both about 3%. Vanadium is seldom lost during burning decarbonization. |
