Coal based Direct Reduction Rotary Kiln Process . The coal based direct reduction rotary kiln process was developed for converting iron ore directly into metallic iron without the melting of the materials.
The reaction occurring inside the bed of iron ore and coal are heterogeneous in nature. Two sets of reaction take place. Set 1: Between coal, carbon dioxide and oxygen Set 2: Between iron ore particles and co.
ABSTRACTSolid-based direct reduction of iron ore requires the reductant coal to have a suitable CO2 reactivity to achieve optimum pre-reduction within a rotary kiln. The CO2 reactivity is affected by numerous factors including coal properties and operating conditions, and is traditionally determined using pulverized samples.
