CASE Introduces Gasifier Technology to Replace Coal Fines ... Abstract. Looking forward to the need of developing coalbased sponge iron technology in India, a country having no significant resources of either coking coal or natural gas, the Research and Development Division of the Tata Iron and Steel Company Limited (TISCO) set up a rotary kiln based direct reduction .

Brief Process Of Coal Based Sponge Iron Rotary Kiln. Looking forward to the need of developing coalbased sponge iron technology in India a country having no significant resources of either coking coal or natural gas the Research and Development Division of the Tata Iron and Steel Company Limited TISCO set up a rotary kiln based direct reduction pilot plant in 1975 .

Study on Accretion Formation on DRI kiln during . In coal based sponge iron technology, the furnace (rotary kiln) fulfils various functions. It is used as a conveying, mixing and charring unit, as a heat exchanger and as a reactor for coal gasifiion and iron ore reduction.

Advantage of Gas Based Vs Coal Based DRI Production: to GAS BASED 1. Clean Technology. 2. Energy Requirement is 20% less than that of rotary kiln based plant. 3. Product suits best steel making qualities. 4. DRI fines (5mm) generated is 5%. Thus, Loss in SMS are less due to low % of fines. 5. Sulphur content in DRI is in range of % which is very low. 6. Average Metallization is 92 ...

 · In a coal based process, the reactor for the reduction reaction is a rotary kiln which is slightly inclined to the horizontal position. The process of direct reduction is carried out with the operating temperatures maintained in a range from 1,000 deg C to 1,100 deg C. In the rotary kiln, both coal and the iron ore feed material is charged from the same end of the kiln. During the movement of ...

Coal Based Sponge Iron Industry Steelworld. Though the industrial appliion of sponge iron started early in the 1950s, it could not fulfill industry expectations at that time in being used as a For a direct reduction in the inclined rotary kiln, ore and coal will normally pass through the inclined kiln in a counter current direction to the oxidising flue gases in the freeboard.

In this communiion, OI methodology is used to study the operability characteristics of direct reduction of iron ore by coal in a rotary kiln using a rigorous process model. Though the objective ...
