· This paper presents an approach to find the best modifiion in the coalbased sponge iron process with an aim to integrate energy in it. For this purpose, a few energy conservation cases are formulated by integrating unutilized energy present in possible areas of process flow sheet. When unutilized energy of the process is properly integrated, energy demand from outside sources can be .
Direct Reduced Iron | Industrial Efficiency Technology ...
Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.

Direct Reduced Iron Industry in India — Problems and Prospects
Such coal based sponge iron is mainly used by induction furnace steel producers leading to technical deficiencies in the steel making process. Further, energy consumption wise, the coal based sponge iron plants are not efficient which can be improved by cogeneration using kiln off gas. CONSIDERATIONS IN SETTING UP COAL BASED SPONGE IRON PLANTS
Sponge Iron
Sponge Iron. 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.
Sponge Iron
Sponge Iron. MSP Sponge Iron plant uses the highest grade of iron ore and premium quality coal. This ensures very high metallization of Sponge Iron. Sponge Iron is fast becoming a significant input in lowcost steel production. With the availability of abundant raw material in India, the production of sponge is set to multiply over the years.
SPONGE IRON PRODUCTION FROM ORE COAL COMPOSITE .
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.

· Coal based sponge iron plant: a conventional process. The process flow diagram of conventional coalbased sponge iron plant is shown in Fig. 1. The operating data shown in Fig. 1 is taken from a typical Indian sponge iron plant. In the conventional process kiln feed, which consists of iron ore, feed coal, and dolomite, is fed to the rotary kiln.
What is Direct Reduced Iron (DRI)
· The process includes two methods, gasbased and coalbased. Depending on the dominant sources of the countries in gas or coal, producers chose one of the methods. Four various procedures of direct reduced iron exist but generally, the pellet, lumps, or fines of the iron ore, in the rotary kiln, confront the gaseous reductants which are a mixture of hydrogen and carbon monoxide.
