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.
India is the world''s largest producer of sponge iron, most of which is produced primarily through the coal based method of production. Growth in the sponge iron production can be attributed largely to the popularity of secondary steelmaking route, which has shown a phenomenal growth in India.
In India, the standard DRI processes are modified in a minor way and thereafter referred to as customized/indigenous technology. Only trivial changes in terms of the feed ratio, length and the diameter of the kiln are made in the name of customized technology. These customized technologies are dominating the coal based sponge iron process in India.
Coalmine auction an opportunity for domestic sponge iron ... 27/06/2020 "A coalgasified DRI plant will yield better quality product (sponge iron) as against a coalbased plant unit and so to that extent this is a good opportunity for the domestic sponge iron industry as coal will be available in abundance," said Bajrang Lohia, chairman Brmaputra Metallics.
Sponge iron produced using the non coking coal is called coal based sponge iron / DRI. For producing the sponge iron through this process requires high grade of iron ore and non coking coal. Gas Based DRI / HBI. In this process route, iron oxides are converted to the DRI / HBI by using natural gas in a vertical shaft furnace. ...
• Sponge iron produced by the process will be the high grade which contains 80% Fe, 12% FeO and 8% gangue material. After separation of sponge iron in the magnetic screen/pulley, the remains are collected as char. Char has good amount of fixed carbon (25% 30%) and moderate GCV (2500 .
MANUFACTURING PROCESS Coal based Direct reduction process is classified based on the reducing agent namely solid. Most solid reduction process use noncoking coal as reducing agent due to abundantly available noncoking coal. The process proposed to be adopted is the rotary kiln proposes using Noncoking coal and iron ore.
SPONGE IRON PLANT. MANUFACTURING PROCESS Coal based Direct reduction process is classified based on the reducing agent namely solid.

be broadly classified into two groups: (1) coalbased DR proces s and (2) gasbased DR process. Details of DR processes, reoxidation, storage, tran sportation, and application of DRI are discussed in
who make sponge iron from coal and iron ore process. Abstract Today India stands as the largest producer of coal based sponge iron through rotary kiln process using calibrated ore and non coking coal However Rotary kiln process suffers from serious limitations like low productivity and pollution In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process
Mar 16, 2013· Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction.
DRI is also known as sponge iron it is a solidstate direct reduction process Fig 26 Coal dolomite and iron ore or pellets are fed into one end of a rotary kiln while sponge iron and char are withdrawn from the other end Primary and secondary airs are supplied to the kiln to initiate combustion and reaction processes Choudhury 2014 .
