Coal based DRI making process. Iron Ore and non-coking coal are the prime raw materials for the production of sponge iron. Jharkhand which comprises a pellet plant, sinter plant, oxygen plant, lime kiln plant, coke oven, sponge iron plant consisting of five kilns, two blast furnaces and a steel melting shop. READ MORE . WIRE RODS .Thus, the sector depends mostly on coal-based sponge iron and nearly 80% of the total coal-based sponge iron plants are located in India. 1 About 60% of this production comes from small-scale industries in the unorganised sector with poor pollution control facilities. 1 During the past decade, these sponge iron plants have rapidly grown Health-related quality-of-life of coal-based sponge iron plant

Analyses of Different Modifications Proposed for the Sponge Iron
Coal-based sponge iron plants have very high average heat to power ratios, often in the range of 25:1 to 31:1 (Choudhury 2014). This reflects that coal-based sponge iron plants use mostly thermal energy in comparison to electrical energy. So, all these studies are aimed to reduce the coal consumption in these plants which is the plants of Orissa, India” A lot of sponge iron manufacturers with rotary kiln are operating in India, and waste heat gas is disposed to the air. Electric generation utilizing this gas is very beneficial to improve. Anil Kumar Prasad, Department of Mechanical Engineering, NIT .

Energy survey of the coal based sponge iron industry
In conventional coal based sponge iron plant, Fig. 1, kiln feed (Stream no. 1), which consists of iron ore, feed coal and dolomite, is fed to the rotary kiln (RK).A separate conveyor collects different size fractions of coal (Stream no. 5) for injection into the kiln with the help of pressurized air (Stream no. 4) from discharge end side.The coal consumption ranges from 950 to 1,000 kg/metric ton DRI as charged. This is equivalent to an energy consumption of 21 to 23 GJ/metric ton DRI, using 23 GJ/metric ton of Indian sub-bituminous coal. Coal consumption at ISCOR is reported to be 800 to 900 kg/metric ton of DRI using 28 GJ/metric ton for South African sub Energy Conservation In Coal Based Dri Plant Electrical India

Design Modifications for Energy Conservation of Sponge Iron Plants
During the operation in the coal based sponge iron plant, a tremendous amount of heat is generated and significant part of this heat, associated with the waste gas, remains unutilized. It appears worth interesting to modify the process that facilitates the integration of heat available with the waste gas. In the present paper, for the utilization of ITECHC Metals Private Limited.
