• How a Coke Plant Works - Gasp

    Oct 04, 2018  Coke is used as fuel in a blast furnace. It plays an important role in the chemical processes that take place in a blast furnace. Coal is heated to about 1250 degrees Celsius in the coke ovens. This process is referred to as ‘dry distillation’ because these coke ovens are oxygen free, so the coal does not actually burn. This process takes ...

    Aug 02, 2019  Blast furnace (BF) remains the dominant ironmaking process worldwide. Central coke charging (CCC) operation is a promising technology for stabilizing BF operations, but it needs reliable and quantified process design and control. In this work, a multi-fluid BF model is further developed for quantitatively investigating flow-thermal-chemical phenomena of a BF under CCC operation.
