Current Request - Overview

Proposed expansion / modernization

The request is for following proposed expansion / modernization in the existing plant

for enhancement in production capacity.

(i) Enhancement in production capacity of Iron Ore Pellet Plant from existing 2.1

MTPA (2 units) with Coal Gasification System to 2.3 MTPA with existing Coal


The company is operating pelletizing plant of 21,00,000 TPA capacity (with 2 kilns of

6,00,000 TPA & 15,00,000 TPA) as a backward integration for utilization of iron ore

fines as pellets in the sponge iron kilns. Grate kiln technology was adopted by us for 2.1

MTPA pellet project.

We now proposes to enhance the existing capacity from 21,00,000 TPA to 23,00,000

TPA. No change in the plant & machinery or capital investment is proposed.

(ii) Change in Product mix of Pelletization plant to include manufacture of Magnetite

Powder / Heavy Media for coal washeries

The company proposes for crushing and grinding magnetite ore to magnetite powder

capacity 2,00,000 TPA in the existing grinding mill unit of Pellet Plants. The magnetite

powder has various uses and finds extensive application as heavy media in coal

washeries. The crushing and grinding of magnetite powder will be done in the excess

available capacity of grinding of existing pellet plant.

(iii) Enhancement of production capacity of from existing 4.00 lac TPA to 5.50 lac TPA

Steel Melting Shop (Billets) by change in configuration of induction furnaces.

The company is operating a Steel Melting Shop through Induction Furnace with a

capacity of 2,00,000 TPA in Phase-I and 2,00,000 TPA in Phase-II with valid

environmental clearances along with other integrated steel manufacturing facilities.

In view of the present scenario and available technology, we propose to enhance the

present capacity of SMS by changing the configuration of induction furnaces to achieve

additional annual capacity of 1,50,000 TPA with total capacity of 5,50,000 TPA


8

(iv) Change in configuration of existing 3 TG Sets {(9 MW + 9 MW + 30 MW) + 10

MW (standby)} with one new energy efficient TG set of 48 MW capacity in the

existing Power Plant.

The company is generating captive power plant of AFBC, WHRB and Biomass based

with total capacity of 73 MW with environmental clearances at Industrial Area, Siltara,

Dist. Raipur, Chhattisgarh along with other integrated steel manufacturing facilities.

The premise is located in the notified industrial area. The details of ECs are as under :

In view of the present technology, we now propose to replace the ageing turbines TG-1, 2

& 4 with a new energy efficient Siemens Make TG set of 48 MW, without any change in

power generation.

The TG-5 with a capacity of 25 MW will remain unchanged, since it is physically

separate from the others and not connected to the common header.

Need for the project and its importance to the Country / Region

Pellet

In India partly due to the sponge iron sector; the overall percentage of lumps usage in

steel making is higher than most other countries. As hard ore reserves is depleting day by

day, lump generation suitable for blast furnace operation is coming down resulting in

production of large amount of surplus fines. Alternative iron making processes for

production of steel may lead to changing pattern of use material inputs and feed stock

causing significant shift in respective share of lumps and agglomerated iron ore (pellets)

and will also enable the use of ores which could not be utilized earlier. As fines forms

considerable part of iron ore resources, value addition to the iron ore fines through

various activities such as Pelletization is the need of the hour.

The Ministry of Environment and Forest also encourages for establishment of Iron Ore

Pelletization plant to utilize the huge stock pile of iron ore fines.

Magnetite Ore

In a global perspective, magnetite has greater importance in several countries compared

to India. China, the world’s largest steel producer, uses magnetite as the major raw

material. Taconite, the principle iron ore in America, contains magnetite as the iron

bearing material. Appreciable deposits are found in Australia and many European

countries, especially Sweden. Other small deposits may be found across countries around

the world.

In India, over 90% of magnetite is found in the southern states of Karnataka (73%),

Andhra Pradesh (14%) and Tamil Nadu (5%). Rajasthan in the west accounts for another

5%. The balance is scattered over Goa, Kerela, Maharashtra, Odisha, Jharkhand,

Chhattisgarh , Assam, Nagaland & Meghalaya.

Government policies favour the beneficiation of coal. The most recent measure is

Gazette Notification G.S.R 02 (E), dated 02 January 2014 and issued by the Ministry of

Environment, Forest and Climate Change (MOEF&CC), which states that “power plants

of capacity of 100 MW or above located between 500-749 km from the pit head shall be

supplied with raw or blended or beneficiated coal with ash content not exceeding 34

percent on quarterly average basis from 05 June 2016. Further, all new coal plants have

been mandated to use supercritical technology and 144 existing plants have been

assigned mandatory efficiency targets that will require use of higher quality coal.

Steel

India was the world’s third-largest steel producer in 2016. The growth in the Indian steel

sector has been driven by domestic availability of raw materials such as iron ore and

cost-effective labour. Consequently, the steel sector has been a major contributor to

India’s manufacturing output.


10

Though the Indian steel industry is going through a sluggish phase, the future remains

optimistic from players with backward and forward integration.

Power Plant

Captive Power refers to generation from a unit set up by industry majorly for its own

consumption. According to the exact definition as per Electricity Act 2003, it is a power

plant set up by any person to generate electricity primarily for his own use and includes a

power plant set up by any cooperative society or association of persons for generating

electricity primarily for use of members of such cooperative society or association.

Captive Power Generations have been growing at a fairly aggressive pace in India.

Industrial sector is one of the largest consumers of electrical energy in India. It consumes

about 45.9 percent of total electricity consumption in the country. The demand for

electricity in India has been continuously growing with time. Thus, to sustain and excel

in the dynamic global environment, it has become imperative for the industries to ensure

uninterrupted power supply for performance optimization which has subsequently led to

the growth in Captive Power Generations in India.

Demand and Supply

Pellet

With the rapid development of Infrastructure and manufacturing sector, the Iron and steel

industry is poised for an accelerated growth. Steel demand in the country is increasing at

an average rate of 10% and is likely to remain in 10-12% range at least for the next

decade. In order to meet the steadily growing steel demand in the country, domestic steel

producing capacity is required to be higher than 150 mtpa within next three years. Indian

economy is growing at more than 10% rate, steel demand and supply will grow in the

same way. As good quality iron ore deposits are depleting fast beneficiation/pelletization

technologies will have to be adopted to meet iron ore demand. Therefore good yield of

pellet process generally around 70% will make this technology economically viable.

� Agglomeration technologies such as Pelletization will have to be added to DRI Plant

/ Steel Plant so that concentrates can be used as feed material. Recycling of cheaper

raw material (fines) by pelletization process as feed material will result in better

Return on Investment as compared to using Iron ore as feed material.

� With superior reducibility behavior of pellets compared to lump ore efficiency of

DRI production improves.

With gradual depletion of high Iron Ore reserves, the Iron and Steel sector world over

has been looking at alternatives to utilise the low grade iron ore fines for iron making so

that there is optimal utilisation of the available iron ore resources. Growth of Steel


11

Industry, especially in China over the years despite the depletion of high grade Iron Ore

has taken place on the strength of technologies of Beneficiation, Sintering and

Pelletisation of Iron Ore Fines, which enhances the productivity of the blast furnaces in

Steel making and hence lowering the cost of steel production.

In the Indian context, by the year 2020, India’s production of steel is expected to touch

110 Million Tonnes and it is imperative that the fines generated in the mining of iron ore

be utilized for the production of steel. The Indian steel industry which predominantly

uses expensive lump ore is gradually moving towards usage of iron ore pellets.

The present Indian raw material scenario offers an opportunistic disposition towards

pellet making owing to the availability of large quantities of sub grade fines, slimes and

blue dust etc. at different mine heads. These materials are not suitable for sinter making.

Pelletization is the only possible route for salvaging these, otherwise waste but valuable

materials. Recent techno-economic studies indicated favorable indices for installation of

pellet plants, both small and large scale. The demand supply analysis also underlines the

need for Pelletization.

Magnetite Powder

Currently the installed capacity of coal beneficiation plants in India is 150 million tons

per annum and is targeted to increase 600 million tons per annum by the year 2025. The

consumption of Magnetite Powder is 1 Kg. per ton of beneficiated coal. Hence the

current requirement is 1.50 lac MT of Magnetite Powder annually which will increase to

6.00 lac MT per annum.

Presently the supply of Magnetite Powder is mix of indigenously manufactured

Magnetite Powder and imported.

Magnetite Powder is extensively used in coal beneficiation plant, as a process of

enriching the quality of coal and reduction of its ash content.

The better grade of coal is not available in India, which requires beneficiation. The

Ministry of Environment & Forests has already made it mandatory for use of

beneficiated coal in power plants of 100 MW capacity and above.

The intrinsic quality of Indian coal, along with the dominant practice of open cast

mining, has meant that run of the mine (ROM) Indian non-coking coal contains a huge

share of ash and other minerals. ROM coal typically has high ash content from 30-50

percent and low calorific value (2,500-5,000 kcal/kg). In general, high ash content

creates problems for coal users that include erosion, difficulty in pulverisation, poor

emissivity and flame temperature, low radiative transfer, and generation of excessive

amounts of fly-ash containing large amounts of un-burnt carbon. In addition, the

transport of ROM coal across long distances is wasteful, as it carries large quantities of


12

ash-forming minerals that results in misuse of rail and port capacity. The transport of

high ash coal across long distances also contributes to emission of carbon dioxide (CO2)

and other greenhouse gases (GHG) from the mode of transport (rail and road).

Global Captive Power Generation Market: Comprehensive Overview

Captive power generation is the power generation unit that has been set up by an

industry or individual for its personal consumption. The industrial sector is one of the

leading consumers of power and is also expected to contribute extensively to the

revenue of the global captive power generation market. Based on captive generation

equipment, the market can be segmented into transformers, electricity precipitators,

heating ventilation air conditioning, heat exchanger, generator, turbine, and boiler

among others. Based on technology it can be categorized into diesel, gas, coal, and

renewable.

Global Captive Power Generation Market: Key Trends

The prime forces of the global captive power generation market are growing demand

for power coupled with the prevalence of cross-subsidy charge in the cost of

generation of per unit of power. Mounting demand across the globe along with

growing urbanization and industrialization and an incessantly rising world population

is expected to boost the adoption of captive power generation. In the near future, the

global captive power generation market is expected to grow at a steady and moderate

rate. It has been anticipated that the market will be mainly driven by the growing

demand for power and the sky rocketing costs of electricity. The demand for captive

power generation is expected to intensify over the next couple of years due to the

existence of the element of cross subsidy in power tariff and rise in per unit cost of

power generation.

The market is also likely to be bolstered by the need for reliable and quality power

couple with decrease in wastes and enhancement of fuel flexibility. The industries

have been compelled to adopt captive power generation and set up their plants in

order to meet their power needs and not depend on the electric grid for power supply.

The growth of the market is also likely to be augmented by the symbiotic relation of

the manufacturing processes with the power generation technologies. Indian power

sector is undergoing a significant change that has redefined the industry outlook.

Sustained economic growth continues to drive electricity demand in India. The

Government of India’s focus on attaining ‘Power for all’ has accelerated capacity

addition in the country. At the same time, the competitive intensity is increasing at

both the market and supply sides (fuel, logistics, finances, and manpower).

Project Description & Manufacturing Process

IRON ORE PELLET PLANT

Enhancement in production capacity of Iron Ore Pellet Plant from existing 21.00 lac

TPA (2 units) with Coal Gasification System to 23.00 lacs TPA with Coal


The company is operating pelletizing plant of 21,00,000 TPA capacity (with 2 kilns of

6,00,000 TPA & 15,00,000 TPA) as a backward integration for utilization of iron ore

fines as pellets in the sponge iron kilns. Grate kiln technology was adopted by Godawari

Power & Ispat Limited for 21.00 lac TPA pellet project.

Now, the company proposes an increase its total production capacity from 21,00,000

TPA to 23,00,000 TPA without any change in the plant & machinery, but only by

change in the following:

1) The pellet plant was designed for utilization of Hematite ore. However, since the fines

generated from our captive mines are primarily Magnetite in nature, the raw material

mix is generally with 50% Magnetite and 50% Hematite. The heat requirement from

Hematite for production of per ton of pellet in terms of calories is more than

Magnetite. Hence, with similar heat input, higher pellet production is envisaged from

magnetite fines.

2) We are also proposing the mix of coal/coke or pet coke as pulverized fuel in the

Gasification system along with Furnace Oil.

Justification for increase in production capacity from 2.1 MTPA to 2.3 MTPA

The ratio of fuel consumption in production of iron pellets from Haematite is about

1.33 to 1.5 times than that of using from magnetite ore.

(Source: Energy & environmental profile of the US Mining Industry Ch IV, pg 9)

Accordingly, even considering the fuel consumption at the lower end of 1.33, the heat

requirement for using a blend of haematitic and magnetite ore will considerably

increase the production by using the same heat input.


19

We must mention here that we have two operating iron ore mines of combined

capacity of 2.1 million tons per annum, the ores of which are predominantly

magnetitic.

A calculation of effective higher production on using hematite and magnetite ore is

given below:

technological process are monitored and administrated by industrious TV with high

automatic control level.

High attention is put on the protection of environment, which purify the dust

contained waste gas by use of high effective dust catcher to discharge into the air after

reaching standard discharge norm.

Dust is collected in centralized manner, which can be fully recovered and utilized.

The Iron Ore Pelletization Plant has the following major units:

Iron Ore grinding system & Filtration

The design capacity of fine grinding machine is 350 T/Hr. feeding fines of incoming

raw iron ore is around 63.5%. Granular sizes of output of iron ore after grinding is

around 70 to 90 passing though 325 mesh, subject to filtration to produce iron ore

concentrate with water content of around 9% to 10%. Preliminary iron ore grinding is

carried out in closed circuit ball mill and Wet screen.

Mixing room

Iron ore fines, Bentonite, flux, coke and ESP dust are all mixed uniformly in a mixer.

As per water content of material, some certain quantities of water is added so as to

maintain water content before balling process ranged from 9 to 10%.

Balling Room

Mixed material is transferred through belt conveyor into the high level of balling

room, where the material mix is discharged through plough-type dumper above belt

conveyor separately into 9 mixed material bunker, under which, 9 sets of Ф6.0m

balling disc are installed. Green ball produced from balling disc is transferred from

collective belt conveyor into the green ball distribution system in the travel grate

machine for material distribution.

Green ball distribution system

Green ball from balling room is fed into the distribution system through belt

conveyor. In reciprocating process, head swinging belt conveyor feed the green ball

into large ball roll screen for screening. Unqualified green ball of more than 16 mm

are separated out and then fed back into the balling room through return material


22

system. Green ball of less than 16mm is fed onto wide belt conveyor, which

transfers the green ball onto roll distributor through AC frequency converter.

Roll distributor fed qualified green ball of 5-16 mm onto travel grate machine.

Undersized balls less than 5 mm are recycled to the balling system.

Baking System

Travel grate machine, rotary kiln and annular circular machine are designed to

formulate baking system. Green ball are dried and preheated in the travel grate

machine, and then baked, solidified in the rotary kiln, cooled in the annular cooler.

Travel Grate Machine

Effective length of travel grate machine is 36 meters for 6.00 lac TPA & 54 meters for

15.00 lac TPA. Length of wind box is 3 meters. The travel grate machine is divided

into 4 zones each unit, which are separately for suction drying zone, preheating

zone I and preheating zone II.

Suction drying zone I & II

In suction drying zone, recoverable hot west gas suctioned by heat resistant fans

from wind boxes in preheating zone II penetrates material layer downward from up,

to keep green ball free of water and dried.

A set of main suction blower is provided to exhaust waste gas from wind box into the

air through ESP.

Preheating zone I

Hot waste gas flow in the preheating zone I is utilized to keep drying green ball

through material layer, in order to assure pellet to sustain high temperature in

Preheating Zone II.

Hot waste gas in preheating zone I is merged through main pipes at a side of wind

box with hot waste gas from suction drying zone to be discharged into air all

together through ESP, Main suction blowers and chimney.

Preheating zone II

In preheating zone II, pellet is further heated. Pellet is partially solidified and

hardened to achieve certain strength to sustain impact caused by pellet falling from

travel grate machine into the rotary kiln to avoid being crushed in process of

rotation of the kiln.

Rotary Kiln

Sizes of the kiln are Φ4.0 mtr. X 32 mtr. for 6.00 lac TPA & Φ5.0 mtr. X 42 mtr. for

15.00 lac TPA.

Pellet, after preheated by the traveling grate machine, is discharged into the end of the

kiln through scrapper and chute. The kiln is provided with HFO & producer gas

spraying gun in its head.


The well baked pellet, is discharged, after large sizes of pellet is sieved out by

fixed screen at the head of the rotary kiln, into the material receiving hopper

Fuel Firing System

In view of better efficiency of heat in kilns and clean coal technology, the company is

adopting a pulverized Coal/Coke/Pet coke firing system along with furnace oil in both

the Pelletizing Plants in addition of coal gas.

Presently we are operating the following Gasification system in both the pellet plants

with valid consents:

• Coal Gasifiers of 16,000 Nm3/hr (4 Nos. x 4,000 Nm

3/hr) &

1 standby of 4000 Nm3/hr in 0.6 MTPA Pellet Plant

• Coal Gasifiers of 40,000 Nm3/hr (10 Nos. x 4,000 Nm

3/hr) &

1 standby of 20,000 NM3/hr in 1.5 MTPA Pellet Plant

We are running into shortage of gas requirement in the existing operating gasification

system total 56,000 Nm3/hr. Originally the coal availability was estimated at CV of

5000 Kcal. However, the present average availability of coal is only CV of 4000 Kcal

CV, hence this is resulting in lower efficiency in the gasification system.

In view of this, we now propose enhance the Gasification system as under in our

pellet plants for better plant utilization.

A) Total gas requirement for our pellet plants 92,000 Nm3

B) Existing capacity of gasifiers 56,000 Nm3

C) Short fall in gas requirement (A – B) 36,000 Nm3

D) Regularization of Consent to Operate for standby

Gasifier of 1 No. 4,000 Nm3/hr and 1 No.

20,000 Nm3/hr (Standby to be made operational)

24,000 Nm3

E) Propose to install additional Gasifier system (4 x

3000 Nm3/hr)

12,000 Nm3

Coal gasification process is one of the cleanest technologies currently available. In the

process of coal gasification, water gas is produced with zero fugitive emission. The

coal gasification process stands better in comparison to other fuels and there is about

50% reduction in the air emissions.

The Coal Gasification Facility consists of:

o Coal sizing

o Coal conveying from ground hopper to top of battery of coal Gasifiers


25

o Coal Gasifiers

o Gas cleaning system consisting of gravity settlers, cyclones and electrostatic tar

precipitator.

o Insulated gas piping

o Process water system

o Ash handling consisting of ash conveyor and storage hopper

o Instrumentation, automation & control for the entire facility

From environmental point view, the usage of producer gas through Coal Gasifier has

proven lowest Nox, Sox, particulate matter and lower hazardous air pollutants. Ash is

in the form of small clinkers / granules and also be slightly wet when disposed.

Therefore, it does not fly and being used for brick making. Water used in the process is

either converted into steam or re-circulated and therefore there is no waste water

stream.

MANUFACTURE OF MAGNETITE POWDER

Change in Product mix of Pelletization plant to include manufacture of

Magnetite Powder / Heavy Media for coal washeries

Magnetite Powder has miscellaneous uses and finds extensive application as heavy

media in coal washeries.

Magnetite is a black/brownish black, naturally occurring iron oxide, represented

chemically as Fe3O4. It is magnetic in nature – hence the name – a property that has

been applied extensively while dealing with the mineral. Being a source of iron, it is

the starting material for many iron & steel producers around the world. Another

application of magnetite, which should be of interest to this industry, is its use as a

heavy media in coal washeries, to separate out higher grades of coal from lower ones.

It is also used as raw material for manufacturing of magnetic tapes.

Use of Magnetite as a Heavy Media

Powdered magnetite is often mixed with a liquid to produce thick, high-density slurry

that is used for specific gravity separations. Much of the high-ash coal that is mined in

India and is floated across a slurry of magnetite. Clean coal particles have a low

specific gravity and float on the slurry. Particles contaminated with pyrite (a sulfide

mineral with a high specific gravity) sink into the high-density slurry.

Use of Magnetite as an Abrasive

The abrasive known as "emery" is a natural mixture of magnetite and corundum.

Some synthetic emery is produced by mixing magnetite with aluminum oxide

particles. The production of synthetic emery gives the manufacturer control over the

particle size and the relative abundance of aluminum oxide and magnetite in the

product. Some finely ground magnetite is also used as an abrasive in waterjet cutting.

In the past few decades, synthetic abrasives have filled many of the applications

where magnetite was previously used.

Other Uses of Magnetite

• Toner in electrophotography,


31

• Micronutrient in fertilizers,

• Pigment in paints,

• Aggregate in high density concentrate

Manufacturing process of Magnetite Powder / Heavy Media

The process of Magnetite Powder is as follows :

The crushed iron ore is passed through the Magnetic Separators wherein the magnetite

ore is segregated from impurities etc. This magnetite ore is then subjected to further

crushing and grinding to the desired micron size. Subsequently the magnetite ore after

being analyzed for its specifications is weighed and packed in PVC bags and supplied

to customers.

For manufacture of Magnetic Powder, the crushing & grinding of ore / fines will be

done in the Grinding mill unit of our existing 6.00 lac TPA & 15.00 lac TPA Pellet

Plants.

We propose to utilize the grinding mill unit of the pellet plant for manufacture of

Magnetite Powder upto 2,00,000 TPA. The crushing and grinding of magnetite

powder will be done in the excess available capacity of grinding of existing pellet

Process Description of the Steel Melting Shop

In this project, we have considered Induction Furnace for producing billet / ingots

and the production of billets to be used for producing structural steel (wire rod /

TMT) from the rolling mill. The furnace is run with electric power fed from the

furnace transformer. The material kept for charging on the charging conveyor is

fed inside the induction furnace and is melted and the same is discharged out of

furnace and is poured to the ladle furnace for further processing in the continuous

casting machine. Steel Billets shall be produced through Induction furnaces to

CON-CAST machines; the main raw-material is Sponge Iron. Power shall be

internally consumed; additionally Steel Scrap and Ferro Alloys as per the

requirement.

Steel melting shop is a department where the metallic scrap and the sponge iron is

being melted in induction furnace. The liquid metal thus melted is treated with

alloys additions for required final product chemistry and cast in to the Billet

through continuous casting machine.

The steel melting shop shall have complete facilities right from Weigh Bridge,

Receiving and processing yard for Raw Materials, Charging Bays, Furnace

Transformers, Cooling Towers, DM Plant, water softening plant, EOT cranes,

storage yards, conveyor systems for feeding, bin weighing system, ladles, ladle

preheater, compressor, pumps, electrical power and control system etc.

The charge mix of Sponge Iron, Steel Scrap and Ferro Alloys are charged in

Induction Furnace as per required chemical composition in the bottom part of

Induction Furnace. All the raw-materials are melted in the furnace with the help of

power and temperature is raised at 1650 to 1680

0 C and liquid metal is tapped in

Ladle. The temperature is measured with Pyrometer. The molten steel is tapped in

ladle and then fed to CONCAST (Continuous Casting Machine) through Ladle to

get the sizes of Billets as per requirement of Rolling Mills.

The sponge iron is fed into the bunkers through the belt conveyor from the sponge

iron plant. From the load out center of the sponge iron plant one conveyor belt has

been considered to the induction furnace shed and a shuttle conveyor is considered

in the shed for filling the bunkers of furnace. From these bunkers each induction

furnace is fed individually through the weight feeders for uniform and regular

feeding of the raw material into the furnace and also to have a proper accounting

of the sponge iron feeding. And rest of the raw material is fed into the induction

furnace by getting it weighed in the platform scale available on the induction

furnace platform. The slag produced in the process, after cooling is sent to the

slag dump.

Environmental Considerations of the Steel Melting Shop

Pollution Control System

The shop is made 100% pollution free by installing state of the art Suction Hood to

individual furnace connected to high capacity suction blower. The system is further

being connected to bag filter, followed by screw conveyor and a stack of required

height.

The plant is further equipped with Natural Draft Exhaust Fans attached to shed for

remaining fumes to atmosphere. It is further to confirm that as the major raw material

is the Sponge iron which never emits any dust or smoke, it just emits heat.

Regarding Water pollution, as all the water circuits are closed loop system no water

effluents are being blown outside the premises. There is no adverse impact on either

air or water quality in and around the plant site on account of installation of the

proposed plant.

The outlet dust concentration is limited to 35 mg/Nm3 through suitable design of the

bag house. Fugitive emission from the LRF is collected using suitable fume extraction

system, connected to bag filter. The shed of casting shop is provided with sufficient

height. Ventilation system at skylight disperses uncollected emissions outside the

shed and maintains clean work environment.

The various noise generating sources in the SMS are feeding systems, casting,

transfer, lifting and placement of steel products. The operations are confined within a

covered shed with skirt boards, which prevents excessive noise from coming outside

the shed and the same is controlled at the desired levels,

The generated solid waste is not a hazardous waste; hence it can be easily disposed to

ground filling & road leveling after recovery of metal.

The measures to control the air pollution are being ensured as per the ambient air

quality standards laid down by Central Pollution Control Board for industrial areas.

POWER PLANT

Change in configuration of existing 3 TG Sets {(9 MW + 9 MW + 30 MW) + 10

MW(standby)} with one new energy efficient TG set of 48 MW capacity in the existing

Power Plant

The existing TG sets of 3 TG Sets [TG-1 : 9 MW, TG-2 : 9 MW, TG-4 : 30 MW] with total

power generation capacity of 48 MW will be replaced by a single Energy Efficient TG set of

48 MW without change in power generation capacity. The process will remain same.

Reasons for Modernization

The change in configuration of existing TG capacity by installation of one new energy

efficient TG set should be viewed as modernization which replaces the existing 4 TG sets

with a new TG set of 48 MW.

This innovative measure of augmenting the capacity of the plant is primarily aimed at

improving the thermal efficiency of the plant as a whole resulting into reduction of heat rate.

Godawari Power and Ispat Ltd. is a designated consumer with Registration No. INS0032CG

with Bureau of Energy Efficiency (BEE) of Ministry of Power which has set a target of

reducing the Specific Energy Consumption by 5% in the present PAT cycle.

In the next PAT cycle, the company has to perform better to meet the more stringent targets

and hence to become more energy efficient.

As the company has covered most of the energy efficiency measures during PAT Cycle-1, to

meet the stipulated target by BEE, the proposed measure of switching over to a new energy

efficient 48 MW TG set by replacing the existing ageing 4 TG sets will go a long way in

achieving this target.

The reduction of heat rate from 3890 Kcal/Kwh to 3440 Kcal/Kwh through this measure will

amount to enhancing the energy efficiency over 10%, which will comfortably meet the target

imposed by BEE towards the reduction of specific energy consumption.

Manufacturing Process

Steam Power Plant

A steam power plant continuously converts the energy stored in fossil fuels (coal, oil,

natural gas) or hot gases into shaft work and ultimately into electricity. The working fluid is


43

water, which is sometime in liquid phase and sometimes in vapour phase, during its cycle

of operation. Power Plant as a bulk energy converter from fuel to electricity using water is a

working medium. Energy released by the burning of fuel is transferred to water in the

BOILER (B) to generate steam at a high pressure and temperature, which then expands in

the TURBINE (T) to a low pressure to produce shaft work. The steam leaving the turbine is

condensed into water in the CONDENSOR (C) where cooling water from cooling tower

carry away the heat released during condensation. The PUMP (P) then feeds the water

(condensate) back to the boiler, and the cycle goes on repeating itself. The working

substance water thus follows along B-T-C-P path of the cycle interacting externally. Since

the fluid is undergoing a cyclic process, there is no net change in its internal energy over

the cycle and consequently, the net energy transferred to the unit mass of fluid, as heat

during the cycle must equal the net energy transfer as work from the fluid.

WHR - The boiler is single drum, natural circulation, balanced draft, water tube and

membrane well type construction. It is a three pass WHR for recovering heat gases coming

from the sponge iron kiln at a temperature of in between 950 to 1050 deg. C.

The first pass is made up of water cooled membrane walls in view of high temperature of

flue gases which enables recovery of radiation heat component in addition to convection

component of heat transfer. The particles carried by the flue gases also add to the non-

luminous radiation heat transfer thus increasing the over all heat transfer. The flue gas

temperature reduces by about 200-250 deg. C in the first pass and enters the second pass of

WHRSG. In the second pass, the super heater coils and flag type Evaporator I bundle are

arranged. Finally the fuel gases pass through the third pass, which is made up of un-cooled

walls/steel casing and contains Evaporator II Bundle along with economizer bundles.

The upper headers of the membrane walls and the evaporator bundles I & II is connected to

the steam drum by risers. Finally, flue gases flows to ESP and steam generates.

Boiler Feed Water System

The feed water from the deaerator is pumped to the steam drum thru an economizer by

multistage feed water pumps, of which two are working and one is standby. The

economizer recovers the heat from flue gases, thereby preheating the feed water before it

enters the steam drum.

Water Circulation

The water circulation system consist of three sections viz. Imbed coils, Conv. Bank Tubes

and Water walls. The conv. bank tubes have self-adjusting circulation pattern, with a few

tubes connected to the water space, serving as down comer tubes and the remaining

serving as riser tubes. A portion of the water circulated is evaporated and the steam water

mixture rises up into steam drum where steam is separated from water. Dry steam leaves

the steam drum, while the water mixes the incoming feed water for further circulation. The

In-bed coils and water walls receive water from water drum through down comers. The

steam water mixture, rising through water wall tubes, enters the steam-drum and the dry


44

saturated steam leaves the drum. The steam drum is provided with suitable internals for

steam-water separation.

Super Heater

The saturated steam from the steam drum enters the convective super heater location at

furnace water walls exit, is of pendant type arranged for counter flow. The heat from the

flue gases is transferred to the steam by convective process and the super heater is suitable

designed to achieve the rated steam temperature. The steam then enters the In-bed super

heater where it is finally super heated pressure.

Combustion Air

The air for efficient combustion of fuel is supplied by primary (FD) fan and secondary

(PA) fan both the fans are provided with Dampers (manual) to regulated the air supply

from the operating platform.

Flue Gases

Fuel gases leaving the combustor; transfer the heat by radiation to the water walls by non-

luminous radiation and convection to the super heater and economizer. The flue gases

leaving the super heater pass through the economizer, which act as heat recovery units. The

gas then flow to the APH and Electrostatic Precipitator (ESP). The ash is collected in the

hoppers provided underneath APH. The hoppers are provided with rotary air lock. One

number ID fan is provided in the flue gas stream, to produce necessary draft to maintain

the furnace under low negative pressure. ID fan inlet damper can be adjusted to maintain

the furnace draft at desired level from operating platform.

Steam Turbo Generator

The steam turbine is a primary mover, which continuously converts the energy of high

pressure high temperature steam supplied by a steam exhausted to a condenser. This

energy conversation essentially occurs in two steps:

1. The high pressure, high temperature steam first expends in the nozzles and comes out

at a high velocity.

2. The high velocity jets of steam coming out the nozzles impinge on the blades

mounted on a wheel, get deflected by an angle and suffer a loss of momentum which

is absorbed by the rotating wheel in producing torque.

Condensor

A condenser, where the exhaust steam from the turbine is condensed operates at pressure

lower than atmosphere. There are two objects using a condenser in steam plant :

1. To reduce the turbine exhaust pressure so as to increase the specific output of the

turbine. If circulating water temperature in a condenser is low enough, it creates a low

backpressure for the turbine. This pressure is equal to the saturation pressure

corresponding to the condensing steam temperature, which, in turn, is a function of the

cooling water temperature. It is know that the enthalpy drop or turbine work per unit


45

pressure drop is much greater at a low pressure than at the high-pressure end of a

turbine. A condenser by lowering the back pressure, thus increases the plant efficiency

and reduces the steam flow for a given output. The lower the pressure the greater is the

output & efficiency. Hence, it is important to use the lowest possible cooling water

temperature. This restricts the temperature rise of cooling water in the condenser tubes

so that the tube outer surface remains low and consequently, the condensing steam

temperature is low and vacuum is high.

2. To recover high quality feed water in the form of condensate and feed it backs to the

steam generator without any further treatment. As a result, only the make-up water, to

replenish the water losses in the cyclic plants needs to be treated.

Circulating Water System

The circulating water system supplies cooling water to the turbine condenser and thus acts

as a medium through which heat is rejected from the steam cycle to the environment.

In closed loop system, warm water from the condenser is passing through a cooling device -

a cooling tower, the cooled tower, and the cooled water is than pumped back for condenser

circulation. However, a natural body of water is still necessary nearby to supply the make-

up water to replace the loss due to evaporation, blow down and so on.

Feed Water System

Condensate collected in the condenser, pumped in the deaerator through regenerative

system.

Deaerator

It is used for the purpose of deaerating the feed water. The presence of dissolved gases like

oxygen and carbon-di-oxide in water makes the water corrosive, as they react with the

metal to form Iron-oxide. The solubility of these gases in water decreases with increase in

temperature and becomes zero at the boiling or saturation temperature. These gases are

removed in the deaerator. Where feed water is heated to the saturation temperature by the

steam extracted from the turbine. Feed water after passing through a heat exchanger –

called vent condenser, is sprayed from the top so as to expose large surface area, and the

bled steam from the turbine is fed from the bottom. By contact, the steam condenses and

the feed water is heated to the saturation temperature. Dissolved oxygen and carbon-dioxide

gases get released from the water and leave along with some vapour, which is condensed

back in the vent condenser, and the gases are vented out. To neutralize the effect of residual

dissolved oxygen and carbon-di-oxide gases in water, sodium sulphite (Na2503) or

hydrazine (N2H4) is injected in suitable calculated doses into the feed water at the suction

of the boiler feed pump (BFP).

Boiler Feed Pump

Feed water after deaeration, transferred to the boiler by boiler feed water pump pressure.


46

Advantages on installation of new Energy Efficient 48 MW TG Set in place of existing

4 Nos. TG Sets :

1) Water Conservation - About 412000 m3 water /year will be saved after installation of

48 mw Siemens turbine. Due to lower specific steam consumption of 4.15 ton

steam/mw there will be decrease in raw water consumption of plant as our old turbines

are having average specific steam consumption of 4.9 ton steam/mw, saving of about

412000 m3 of water per annum.

2) Saving of demineralised water- About 12000m3 of water/year will be saved after

installation of 48 mw Siemens turbine and will ultimately result in monetary saving.

3) Saving due to reduction of auxiliary power-we will save about 5424000 kwh/year

due to reduction in aux power above saving of auxiliary power will be achieved as we

will be having only one (1) boiler feed pump operative against presently operated four

(4) bfp.

- we will be having only one (1) condensate extraction pump operative against

presently operated three (3) CEP pumps.

- we will be having only one deareator charged against presently charged three

deareators by installation of single deareator we will be able to achieve more deareator

temperature as compared to split deareator.

- we will save steam for hogger ejector as we will be charging only single ejector

against three ejectors after installation of 48 mw single turbine.

4) Ease of plant operation

Single turbine instead of four numbers of turbine reduce the complexity of plant

operational parameters & reduce plant equipments tripping. Bleed charging availability

is for all time. It will reduce the chances of malfunctioning as well the required less

spare items. During any change in load there are no chances of load shifting from one

turbine to another turbine.
