摘要：
Coal and energy consumption in the COREX process can be minimised from the balance between the required and generated reduction gas. Metallisation ratio is calculated at the balance, which corresponds to the effective calorific value of smelting coal. The proper metallisation ratio will be defined in this paper, after which it is demonstrated that an effective calorific value of smelting coal is needed to minimise the consumption of energy in the process. In addition, heat stability is also an important parameter when using coal instead of coke to insure a useful fixed bed in the melter gasifier. By considering the above points the energy consumption in the COREX process can be optimised.
