ALTERNATIVE MATERIAL FOR DUST COAL AT ELECTRIC ARC FURNACE USING DUSTS FROM COKES DRY QUENCHING SYSTEM REDUCING ELECTRICAL ENERGY

摘要

PURPOSE: To provide an alternative material for a dust coal, which is used for melting incineration ashes in an arc furnace, by using dusts generated from a cokes dry quenching system, thereby providing smooth melting, uniform molten body and reducing an electrical energy. CONSTITUTION: The dust generated from a cokes dry quenching system comprises 0.35-0.8 wt.% of moisture, 10.5-12.3 wt.% of lime powder, 0.85-1.1 wt.% of volatile component, 86.3-87.8 wt.% of fixed carbon, and is used for melting incineration ashes in an arc furnace.
