With the availability of raw materials, high demand of sponge iron and less payback period, sponge iron industry has emerged as a profitable venture. However, due to lack of proper integration techniques, non-optimal process parameters, high-energy con-sumption and old running process technology, the industries are facing a setback in market.

out. The role of kiln is to convert the raw material (iron ore, coal and dolomite) into the sponge iron [8]. Detail reaction mechanism of the process is discussed below: There are two reduction reactions. First reaction converts iron ore to iron oxide which further reacts with CO to produce metallic iron (Fe) which is called sponge iron.

Sponge iron is a highly processed form of iron ore that contains metallic iron in the range of 83-88% obtained by direct reduction through reaction with carbon in the form of coal at approx. 1100 degree Celsius. Due to high porosity, the resulting iron is called sponge iron. Sponge iron is also referred to as direct reduced iron or metalized iron.
Direct Reduced Iron / Sponge Iron Process (DRI) The process of reduction takes place inside the rotary kiln, which is mounted on tyres and supported by support rollers.
