  • COREX — SMELTING REDUCTION PROCESS

    The coal is charged inside the melter gasifier, so even non-coking coal can be used, which makes a coking plant unnecessary. The high dome temperature exceeds 1,000C, resulting in cracking of the coal's relieved hydrocarbons and avoiding the formation of tar. The cost of Corex coal is approximately 40% lower than for coal used in blast

  • Coal Drying Improves Performance and Reduces Emissions

    Coal feeders provide coal to the coal pulverizers (mills) where the coal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill. This results in increased mill exit
