Abstract: The present work is an approach for conservation of energy in the coal based sponge iron industry by heat integration and incorporating certain design modifications without disturbing the SL/RN process technology involved in the sponge iron production. Although the making of sponge iron through direct reduction is being practiced in India, it still is having loopholes due to the non-optimal process parameters, high energy consumption and old running process technology motivation of the present work.The waste heat recovery in the process is done using waste gases exiting from ESP. For this purpose a case study of typical Indian sponge iron process of capacity 100 tpd is considered. After a complex reduction and combustion process waste gas exits the sponge iron plant at substantially higher temperature which is around 200-220C. At this range of temperature waste gas carries a lot of sensible heat which directly goes to the atmosphere through chimney.To apply heat integration on t...
