1.3 Manufacturing Process

1.3.1 Sponge Iron (DRI)

Refractory lined rotary kilns will be used for reduction of iron ore in solid state. A central

Burner located at the discharge end will be used for initial heating of the kiln.

Iron ore will be continuously fed into the kiln along with coal which has dual role of fuel as

well as reductant. Dolomite will be added to scavenge the sulphur from the coal. A

number of air tubes will be provided along the length of the kiln. The desired temperature

profile will be maintained by controlling the volume of the combustion air through these

tubes. The Carbon monoxide generated due to the combustion of coal, reduces the iron

ore and converts it into sponge iron. The rotary kiln is primarily divided into two zones viz.

the pre heating zone and the reduction zone. The preheating zone extends over 30 to 50

% of the length of the kiln and in this the moisture in the charge will be driven off and the

volatile matter in the coal will be burnt with the combustion air supplied through the air

tubes. Heat from the combustion raises the temperature of the lining and the bed surface.

As the kiln rotates, the lining transfers the heat to the charge. Charge material, pre-heated

to about 10000C enters the reduction zone. Temperature of the order of 10500C will be

maintained in the reduction zone, which is the appropriate temperature for solid state

reduction of iron oxide to metallic iron.

This hot material will be transferred to Heat exchanger. In Heat exchanger the material

will be cooled to 1600C. The cooler discharge material consists of sponge iron lumps,

sponge iron fines and char. Magnetic and non-magnetic material will be separated through

magnetic separators and stored in separate bins. The hot flue gases will be taken to a

Waste Heat Recovery Boilers and after heat recovery they will be treated in high efficiency

ESP and discharged into the atmosphere through stack whose height will be in accordance

with CPCB norms.

1.3.2 Sinter Plant

The proposed sinter plant complex will consist of one sinter Machine of suitable grate area

along with associated services facilities. The sinter plant is rated for a total production of

10,08,000 TPA of BF Sinter.

1.3.3 Blast Furnace

The blast furnace shop will comprise of furnace of capacity 1 x 2160 TPD. The blast furnace

is envisaged to operate with sized lump Pellets, coke, fluxes and additives. The hot metal

produced will be cast at pig casting machines to produce cold pigs. The liquid slag will be

granulated at cast house granulation unit. The BF top gas will be cleaned in dust catcher

and gas cleaning system and distributed to the stoves, burners for runner drying, boilers

for process and process steam supply. The surplus gas will be utilized for power

generation. 30 MW power will be generated with BF gas.

1.3.4 Power Generation

1.3.4.1 Through WHRB Boiler

The hot flue gases from DRI kilns will pass through waste heat recovery Boilers to recover

the heat and to generate 2 x 15 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.

1.3.4.2 Through PCF Boiler

The concept of burning coal that has been pulverized into a fine powder stems from the

belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a

gas. The feeding rate of coal according to the boiler demand and the amount of air

available for drying and transporting the pulverized coal fuel is controlled by DSC / PLC.

Pieces of coal will be crushed between balls or cylindrical rollers that move between two

tracks or "races." The raw coal will then be fed into the pulverizer along with air heated to

about 343oC from the boiler. As the coal gets crushed by the rolling action, the hot air dries

it and blows the usable fine coal powder out to be used as fuel. The powdered coal from

the pulverizer is directly blown to a burner in the boiler. The burner mixes the powdered

coal in the air suspension with additional pre-heated combustion air and forces it out of a

nozzle similar in action to fuel being atomized by a fuel injector in modern cars. Under

operating conditions, there is enough heat in the combustion zone to ignite all the

incoming fuel. 330 MW of power will be generated.

1.3.4.3 Through Blast furnace

The blast furnace gas coming-out from the furnace will be used as fuel for stoves, Ladle.

Any excess gas will be let to Sinter Plant as fuel. A total of 30 MW will be generated by

utilizing flue gases from blast furnace.
