For the direct reduction of iron ore the main furnace used is rotary kiln. The rotary kiln is the refractory lined cylindrical vessel on which blowers are mounted & the air pipes, to provide combustion air to the inside of the kiln. During lite up there is a start up burner at the kiln discharge end which is oil fired to heat up the rotary kiln.
Boudouard reaction, dolomite, DRI, Iron ore, metallization, non coking coal, pellets, reduction, Rotary kiln, Sponge iron, Sulphur, 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.
Iron ore fines are usually subject to beneficiation and/or pelletisation thereby converting them back into hard rock-like shapes (pellets) with a proper tumbler index. These pellets are then used for making sponge iron. Rotary kilns have a drawback upon the size and quality of iron ore that can be used.
