Direct Reduction Process - an overview | ScienceDirect Topics
DRI is also known as sponge iron, it is a solid-state direct reduction process (Fig. 2.6). Coal, dolomite and iron ore or pellets are fed into one end of a rotary kiln, while sponge iron and char are withdrawn from the other end.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). Coal supplies the required heat to raise the temperature up …
Direct Reduced Iron and its Production Processes – IspatGuru
Mar 16, 2013 · In a coal based plant the reactor for the reduction reaction is a inclined horizontal rotary kiln. In this kiln both coal and the iron ore feed material is charged from the same end of the kiln. During the movement of feed material forward the oxidation reaction of carbon in coal and reduction reaction of CO gas is carefully balanced.
Tunnel Kiln – Electrotherm – Engineering & Technologies ...
Quality of sponge iron made by the Tunnel Kiln technology is superior as compared to that made from the rotary kilns because, while the input raw material gets just about 24hours for the reaction, the figures almost reverse in case of the Tunnel Kiln. Reaction time of 42 hours in the Tunnel Kiln provides ample opportunity for the raw material to completely react and this results into superior Fe …

Oct 11, 2019 · Reduction is the process of electrons being donated to a metal/element/surface through some set of reactions, while another component in the same set of reactions is oxidized (electrons lost). This is your defined set of oxidation and reduction parameters. In a gas kiln, albeit natural gas or …
Direct reduced iron - Wikipedia
The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles. The direct reduction process can use natural gas contaminated with inert gases, avoiding the need to remove these gases for other use.

Reduction Firing - digitalfire.com
In traditional ceramics, reduction firing requires a specially designed fuel fired kiln that restricts the flow of incoming air so there is enough to burn the fuel and no more (in some cases it is restricted so that is actually less than enough to introduce carbon into the atmosphere).
