This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed.
The increase in the demand of sponge iron is also due to the fact that it is used as a substitute for coking coal which is available in scarcity in the world. This book comprehensively deals with the production of sponge iron in the rotary kiln. The book is divided into 17 chapters. The initial chapters give a brief on the fundamental theories and basic principles of sponge iron production .
Looking forward to the need of developing coal-based 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. In this pilot plant, a totally indigenous technology for production of .
6. The product i.e. Sponge Iron and semi burnt coal are discharged from the kiln through a rotary cooler. The cooler is 12M in length and water is sprayed directly as well as indirectly for cooling the material. The material is cooled down to 100oC and fed to magnetic separator for separating the sponge iron and non-magnetic (char). The Sponge .

For the direct reduction of iron ore the main furnace used is rotary kiln. The rotary kiln is the refractory lined cylindrical vessel on which blowers are mounted & the air pipes, to provide combustion air to the inside of the kiln. During lite up there is a start up burner at the kiln discharge end which is oil fired to heat up the rotary kiln.
