Case2 In this case the hot sponge iron is used to heat water through a water bath around rotary cooler, shown in Fig. 3, and further preheating of air is carried out using this hot water using a longi tudinal ﬁn double pipe heat exchanger, shown in Fig. 4. The design .
In the present work a system is designed to integrate the heat of waste gas in the sponge iron process. For this purpose a case study of typical sponge iron production process is considered. Waste gas from the rotary kiln of the sponge iron plant exits at a temperature around 900 C.

The first reaction step is the production of, process, iron, In the BOF process ...
Metallization varies from 83 92% and carbon does not exceed %. Sponge iron is discharged from the kiln at approximately 800 1000°C. Off gases produced in the kiln contain considerable sensible and chemical heat, the recovery of which represents the biggest opportunity for improving energy efficiency in this process.
Hot sponge iron along with semi burnt coal exits the kiln from the discharge end at 1000ºC. It consists of Fe ( tph), char ( tph) and ash ( tph). It enters the rotary cooler where water is sprayed over the cooler and the temperature is brought down to about 120 ºC.
This is the case study of typical coal based sponge iron plant of 500 tonne per day capacity. The process flow diagram (PFD) of the sponge iron process is shown in Fig. 1. Different streams in the PFD are assigned individual number and henceforth each stream will be referred through its respective number.

This book, earlier titled as Sponge Iron Production in Rotary Kiln, is revised as per the feedback from students, faculty members and professionals. It, now, covers broad spectrum of alternative routes of iron making, therefore, the book is renamed as Alternative Routes to Iron Making.
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 noncoking coal [Patra et al, (2005)]. The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed.
