About Company:

Jayaswal Neco Industries Ltd. (JNIL) is one of the reputed manufacturers of Iron and Steel and foundry products in the country.

 

JNIL is operating a large Integrated Steel  Plant near Raipur and captive coal mines near Tamnar in Chhattisgarh.   

 

********************************          

 

As 0n  September 04, 2012 : The Project is in planning stage.

 

The  project  requires  210.8 hectares of Land.

 Out of  this  from Dagori  Village 82.96 hectares, from Ameri Akbari  Village 75.214 hectares and from Udgaon  Village 75.214 hectares are being aquired.

 

33% land shall be developed as Greenbelt.

About 181500 trees, shrubs and herbs shall be planted on

72.6 hectares land area. 

 

IMPORTANT: As per the discussion we had last  on 27.08.2012  with  of Jayaswal Neco Industries Limited   the Project is under planning stage.

 

The company is now  in the process of aquiring the land required for the entire project.

 

The Environment Clearnces for which company has applied earlier is now in place.

 

The project work is likely to start from

Early 2013.

 

The Project   is Scheduled to be  Completed

By   June,2014 .

 

So, this is the RIGHT TIME to contact  and Follow Up at following address obtain the detailed Enquiry of each product  in time and to submit your quotation subsequently.

 

The Main Scope of Supply includes:

Captive Power Plant : 100 MW

(WHRB: 25 MW + AFBC  : 75 MW)      

1.Waste Heat Recovery Boiler: 

From  Coke Oven Gas     : 12 MW

From Blast furnace Gas  : 13 MW

 

DRI Kiln gas shall be used in  WHRB. 

The hot flue gases from above will pass through waste heat recovery Boilers to recover the heat and to generate 25 MW(12 MW + 13 MW) electricity.

The gases after heat recovery will pass through ESPs and then discharged through chimneys into the atmosphere for effective dispersion of emissions into the atmosphere.

2.Fluidized Bed Combustion (AFBC) Boiler:

In this section  high pressure  steam is produced using pressurized

boilers, which are fed to turbines for generating electricity.

 

Coal, middlings and dolochar shall be used as fuel in the AFBC/CFBC boiler.

   

Total dolochar generated will be used in AFBC Boiler along with coal to generate   75 MW ( 3 X 25 MW)  electricity.

The flue-gases will be treated in high efficiency ESP and then discharged through stack into the atmosphere. 

.

Heat Exchangers, Air Pre-heater/Economiser) to be included both type of Boilers.

 

3. DRI Klin                            : 2 X 500 TPD

4. Iron Ore Crusher  

5. Electric Arc Furnace        : 1 X 80 Ton

6. Ladle Refining Furnace   : 1 X 80 Ton

  

Raw Materials

Iron ore fines (1806,800 TPA), Iron ore lump (972,000 TPA), Coal  (906,000 TPA), Middlings (50,000 TPA), Coking coal (280000 TPA), Dolomite (47280 TPA), Limestone (116,000  TPA), Calcined Lime  (28510  TPA),

Calcined dolime  (39798 TPA), Ferroalloys (28005 TPA) and    Bentonite  (10000 TPA) will be used as raw materials.

 

Manufacturing Process  :

 

Iron ore Beneficiation and Pellet Plant: 

Iron ore fines will be  grinded to liberate the alumina and silica and then washed using water to beneficiate the ore.

Iron concentrate and tailings will be formed.

The concentrate will be mixed with grinded limestone, coke fines and benonite along with water. 

The nodules formed will be taken to indurating  furnace.

The nodules will be  converted to pellets.

 

Sponge Iron Plant:

Crushed raw materials (Iron ore, coal & dolomite) will be fed to the  kiln.

Coal  will be providing the source of heat and also acts as reducing material to turn iron  ore into iron. Sponge iron produced will be  separated from waste materials in magnetic separator, screened and sent to steel making shop. 

 

Blast Furnace:

It is a vertical furnace. Sinter, iron ore, coke and limestone will be   charged from furnace top that slowly travels down and comes in contact with upcoming hot air. Coke reduces iron ore to iron and also supplies heat.

Iron ore gets  converted to iron and impurities will be  converted to slag, which will be  taken out at regular intervals.

Blast furnace gas will be reused as fuel in the blast furnace stoves.

The  molten iron will be converted to pigs or will be directly taken to steel melting shop.

 

Steel Melting Shop:

Pig iron, sponge iron, lime and ferroalloy will be  charged from the top

of Electric Arc Furnace. Arcing melt the contents.

Oxygen blowing will be  done. Steel will be  tapped and chemistry correction will be  done in Laddle Refining Furnace. Liquid steel will be casted into billets in continuous casting machine. Slag will be  taken out from slag tap hole. 

 

Rolling Mill:

 

Steel billet will be  rolled into different products in the Rolling Mill.

 Mixed Blast Furnace Gas and Coke Oven Gas will be used as fuel in the reheating furnace.

 

Sinter Plant:

Sintering process utilizes iron from waste materials that would otherwise

be dumped as wastes.

Iron ore fines and dust containing iron, mill scales, limestone, coke and coal fines will be mixed, converted to nodules and sintered in sintering furnace.

 

Air Pollution Control Equipment :

Electrostatic Precipitators/ Bag Filters

 

Particulate emissions from the plant will be controlled within 50 mg/Nm3.

 

The plant shall be provided with Electrostatic Precipitators

having high efficiency (above 99.98%) for collection of the fly ash that would

be produced from the Process of coal combustion in Boiler Furnace.

An  Electro Static Precipitator would be provided for the cleaning / detarring of the Producer gas and the flue gases.

 

Stack of adequate height will be provided at the respective units.  Water sprinkling will be done along the haul roads to control dust arising from vehicular movement. Dry quenching of coke shall be explored.

 

Coal from the coal yard will be crushed in a Crusher and conveyed to coal storage bunkers of Boilers through a system of Conveyor Belts, Crusher and Vibrating Screens and is fed to the furnace.

 

ESP, Dust Extraction systems for Conveyor Transfer Points, Crusher and Screen house with Hoods, Bag filter and Fans will be provided.

 

De-mineralised water from the storage tank will be pumped to the boiler with the

aid of Boiler Feed Pump. The boiler feed water through an Economizer will

the Steam drum and water walls where it is heated and converted to

saturated steam.

 

The steam from the main steam header will be  taken to the

Turbo–Generators. After rotating the turbinethe exhaust steam is

condensed in the Air Cooled Condensers and the

condensed water is pumped to the De-Aerator and fed back to the boilers.
