In the rotary kiln where the charge containing iron ore and solid fuel is exposed to an atmosphere of carbondioxide and nitrogen, the reduction must be taking place in the following sequence: (i) the formation of carbonmonoxide according to reaction 1(b) followed by (ii) the reduction of iron oxide by carbonmonoxide, reaction 1(a).
Tunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore cake are directly used for manufacturing of sponge iron in tunnel kilns. The material bed in Tunnel kiln being stationary, it does not require high strength and .
Use of coal gas in place of coal makes the tunnel kiln project environmentally clean and safe. Both hematite and magnetite ores can be used in the tunnel kiln. The process is more suitable for soft ores, such as blue dust. The tunnel kiln process can reach higher metallisation levels of 9092%, as compared to 8688% in the rotary kiln.

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.
Sponge Iron Production in Rotary Kiln Bidyapati Sarangi . The testing includes iron ore testing, thermal disintegration testing, reducibility testing, and swelling and bed permeability testing. Further, it details on the reduction of iron oxide inside the rotary kiln. The entire rotary kiln plant and its functionalities are explained with precision.
direct reduction of iron ore from tunnel kiln process. Oct 15, 2016The latest technology in the DRI (Sponge Iron) making is utilizing the Iron Ore Fines directly to produce the Sponge Iron( DRI) and subsequently producing the CBI cold brquetted Iron, which has the multiple benefits, like: 1) .
rotary kiln direct iron ore reduction direct reduction of iron ore from tunnel kiln process. direct reduction of iron ore from tunnel kiln process Coal Technology Springer The United States contains about onethird of the world's coal reserves, and coalrepresents over 90 percent of proven reserves of fossil fuels.
Tunnel Kiln Coal based DRI plant. And coal of minimum "B" grade was required to be used for the solid state reduction or DRI making process. With the passage in time, quality of both iron ore and coal declined and still DRI was being produced. However, the only solution for iron ore fines was beneficiation, if required, and pelletisation.
