Thus, the sector depends mostly on coalbased sponge iron and nearly 80% of the total coalbased sponge iron plants are located in India. 1 About 60% of this production comes from smallscale industries in the unorganised sector with poor pollution control facilities. 1 During the past decade, these sponge iron plants have rapidly grown in the
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 million tones per annum. In a span of 20 years the industry has grown rapidly and the present estimated capacity is nearly million tones.
Objectives During the last decade, coalbased sponge iron plants, a highly polluted industry, have grown rapidly in Barjora, India. Understanding their workers perception of health is essential in peoplecentered healthcare. The aim of the study was to assess their healthrelated qualityoflife (HRQoL), and to determine factors that independently predict their HRQoL.
Such coal based sponge iron is mainly used by induction furnace steel producers leading to technical deficiencies in the steel making process. Further, energy consumption wise, the coal based sponge iron plants are not efficient which can be improved by cogeneration using kiln off gas. CONSIDERATIONS IN SETTING UP COAL BASED SPONGE IRON PLANTS
The production of sponge iron in India started about three decades ago triggered by the fact that in the mid1970s, Indian ministeel plants started examining the viability of setting up sponge iron plant. Since India has adequate coal deposits, production of coal based sponge iron was considered a
Sponge iron is a type of iron produced by coal based or gasbased reduction of iron ore. It is difficult to measure and control the degree of reduction or quality of the iron ore at intermediate
Using coal for reduction of iron ore has severe environmental issues as it leads to emission of carbon in great proportions. This is the reason why the world today prefers gas based sponge iron. Galaxy Enterprise is manufacturers and exporters of high quality gas based sponge iron and supplies it to steel plants in the India and overseas country.
Sponge Iron Plants: For the Sponge Iron manufacturing there are two main processes Coal based and Gas based . In Coal based process noncoking is used as reductant in which is available plenty in India and can be established in smaller modules. As such coal based sponge Iron plants have come up now in large number.
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 ores are suitable for direct reduction. Direct reduction refers to solidstate processes which reduce iron oxides to metallic iron at temperatures below the melting

Sep 01, 2015#0183;#32;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.
Commissioned in 1991, the Raigarh plant has a manufacturing capacity of MTPA and metallic iron content of more than 81%. The plant uses direct reduced iron (DRI) process method of production and utilises ten indigenously developed rotary kilns (6 kilns of
The major quality requirements of coal for Sponge iron production are 1) Noncoking characteristics 2) Low ash content 3) Low sulphur content 4) Good reactivity 5) High ash fusion temperature 6) Medium volatile matter 1). Noncoking character: Noncoking coal is required in sponge iron
