Non-coking coal is required in sponge iron production, since the Coal based Direct reduction process is classified based on the MAJOR PLANT FACILITIES 1- RAW MATERIAL PREPARATION SYSTEM Raw material system mainly consist Vibro Feeder, Crusher and Screen.
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
It is based on Coal Char coming out of Kiln for economical generation of power. One 6 MT Induction Furnace using electrical energy produces Ingots of high quality. Sponge Iron produced is used as a mix Raw Material for producing Ingots. Plant also has one Cone Crusher for Iron

Recovery and utilization of waste heat in a coal based sponge iron process A typical sponge iron plant has been investigated to ﬁnd out the potential areas where energy is being wasted. To recover heat from these areas two design modiﬁcations, Case
Boudouard reaction, dolomite, DRI, Iron ore, metallization, non coking coal, pellets, reduction, Rotary kiln, Sponge iron, Sulphur, Coal based Direct Reduction Rotary Kiln Process . The coal based direct reduction rotary kiln process was developed for converting iron ore directly into metallic iron without the melting of the materials.
In conclusion, many coal-based sponge iron plant workers in Barjora report problems in their HRQoL, and the predictors of different aspects of HRQoL were identified. The study findings could be taken into consideration in future interventional studies aimed at improving the HRQoL of these workers.

PAT and coal based DRI: Sponge Iron industry comes under Iron & Steel sector with sectoral energy reduction target of 1.56 mMTOE(million metric tones of oil equivalent). For a coal based DRI plant with waste heat recovery boiler, power plant and having arrangement for selling surplus electricity, the gate in energy would be coal
of industrial plants for the hot briquetting of direct reduced iron went into operation. Ad- The entire plant for the hot briquetting of sponge iron typically consists of (Figs. 6 and 7): (coal based reduction) Figure 9: Cross sections through briquettes made with material from different direct reduction processes.
We are the largest producer of sponge iron using non coking coal as a reductant and and are having the largest coal based plant in the world. We shall discuss in detail all technical aspects of coal base sponge iron making with particular reference to control of important process parameters to achieve quality sponge iron in this august gathering.
Dec 14, 2013 Direct Reduced Iron. Direct reduced iron (DRI) is also known as sponge iron. It is produced by the reduction of iron ore (in the form of lumps or pellets) by either non-coking coal or a reducing gas produced by reforming of natural gas. The reducing gas can also be produced by the gasification of coal. The reducing gas is normally a mixture.
Sponge iron is produced primarily both by using non coking coal and natural gas as reductant and therefore classified as coal based and natural gas process respectively. Presently, there are 118 large and small sponge iron plants in India- 115 of them are coal based while only 3 are natural gas based. The advantages of sponge iron are:
Development of coal based sponge iron processes with particular reference to India : A coal based sponge iron plant was first built in 1980 at a place called Paloncha in Andhra Pradesh which had a capacity of just 0.03 million tones per annum.

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.
Iron and Steel Making Machines Pioneers in the industry, we offer induction melting furnace, rotary kiln coal based dri plant, tunnel kiln coal based dri plant, modular billet caster, electric arc furnace and vibro feeder from India.
Jan 22, 2019 Sponge iron or direct-reduced iron (DRI) is a transitional material used in the production of steel. Either coal or natural gas is used in sponge iron production. In India, non coking coal is easily available. 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 .
