GASIFICATION & GASIFIER Advanced & improved renewable energy systems.

Thermo –chemical process.

LHV (Low Heat Value)

Cost efficient process

End product is called “Producer gas”.

GASIFIER  The equipments to be utilized for gasification of solid fuels are known as

GASIFIER. On the basis of flow of gas in the reactor, gasifiers are generally

divided in three major groups like, UPDRAFT, DOWNDRAFT & CROSS DRAFT.

An updraft gasifier is more efficient & comparatively easy to operate.

GAS CONDITIONING , TRANSMISSION & DISTRIBUTION

Gas produced in gasifier contains impurities like, ash particles, coal dust,

tarry acids & mist in vapour form. These all impurities are removed from

the gas by passing it through a train of filters. The gas filtration system

applies various principles & techniques for different impurities. The level

of filtration to be provided depends upon the application of gas.

GAS TRANSMISSION & DISTRIBUTION

Conditioned producer gas shall be transmitted & distributed as per

requirement of end applications.

FEATURES & ADVANTAGES

The Coal Gasifier system is capable of gasifying several types of solid

fuel such as Charcoal, Imported Steam coal, Briquettes at high efficiency.

Low No formation due to low flame temperature.

Absent / Negligible Sox formation due to very low sulphur content in Coal.

Extremely Low Particulates and smoke emission due to the complete

direct firing of Producer Gas compare to solid fuels / liquid fuels firing.

Worldwide accepted environment friendly Renewable Energy technology.

Reduced scale losses in comparison with liquid fuel firing.

CHEMICAL COMPOSITION & CHARACTERISTIC

The Gasifier can convert any type of coal into Producer Gas. The chemical composition

of Producer Gas is as under;

CO (Carbon Monoxide) : 20 ± 2%

CH4 (Methane) : 03 ± 1%

H2 (Hydrogen) : 15 ± 5%

CO2 (Carbon Dioxide) : 10 ± 2%

N2 (Nitrogen) : Rest

Calorific Value of Producer Gas : 1300 – 1375 K.Cal/NM³

Producer gas temp. at gasifier outlet : 120 – 150oC (Before filtration); 40 – 60oC (After filtration).

Max. Flame temperature : 1350ºC

SILENT FEATURES OF JINDAL PROJECT

• Poking free plant (16 month regular gas supply without taking shut down).

• Equipped with digital ETP.

• 1.2 km pipeline from gasifier site to quenching & tempering furnace.

• 1.6 km pipeline from gasifier site to hot mill (RTHF).

• Used advanced technology Gas Reactor.

• Extended shaft gasifiers enable efficient gasification which gives coal free

white ash.

At M/s Jindal Saw Ltd. Sinnar, Nashik, [Jindal Group Company] we have installed a state-of- the Art plant wherein we had setup a battery of 4 gas plants [each 9000kW] and supplying the gas to three different applications. Out of these four plants 2 units are in operation since Aug. 2009 and have been running on 24x7 basis. Since the commissioning of first 2 plants the first shutdown was taken after 16 months of continuous running that too after our insistence to stop the units so that we canconnect the newly erected another 2 plants. Now all 4 plants are running successfully in full automation and synchronization with individual furnace’s gas requirement. We have executed this project on turn-key basis with Coal handling, Gas cleaning system [Electrostatic Precipitators].

SPECIALITIES IN ROLLING MILL PROJECTS

• We take pride in being the first gasifier company in India who has successfully

converted a 16-18 TPH billet reheating furnace with charge section from 125 x 125,

160 x 250 & 250 x 250 at Bengal Hammer Industries Ltd. Kolkata. This plant is running

successfully for more than a year now. Moreover within this unit 2 furnace are running

simultaneously with single gasifier of 8000 KW, feeding two rolling mills each of 10” &

26”.

We have adopted the generation technology of Gas Producer which could give a

consistent gas supply at a much higher calorific value (1500 to 1650 Kcal/Nm as

against a C.V of only 1150 to 1250 Kcal/Nm from old single stage design) owing

to its unique feature of pre distillation of feed coal in its deep coal bed in the

extended shaft while moving downwards to the reduction and oxidation zone

counter current to the upward flow of product gas which strips off the

considerable quality of volatile matter from the in-coming feed stock making it

semi-coke and highly reactive for a faster gasification. Simultaneously, the

product gas also becomes enriched with the volatile matter of coal to a higher

calorific value. Fed coal travels downwards and gets dried first and then gradually

preheated up to a distillation temperature of about 450oC by the product gas

moving upwards which itself gets gradually cooled down and picks up the volatile

matter of coal and gets auto-carbureted to a much higher calorific value before it

comes out to the L.T.C off take pipes. The coal, on the other hand, gets

carbonized to nearly coke stage and its reactivity increases for a faster

gasification.

BRIEF DESCRIPTION OF PROCESS

Page 16: Urja thermal solutions

When the coal enters through the generator bottom shaft, reaction between coal and (air + steam) occurs and following reactions take place from bottom oxidation zone to top reduction zones  A) Oxidation zones: Reaction is : C + O2 CO2 + 42643 K. Cal  B) Primary Reduction zone : Reactions are : C + H2O CO + H2 – 19000 K. Cal C + 2H2O CO2 + 2H2 – 19307 K. Cal

C + CO2 2CO – 18689 K. Cal C) Secondary Reduction zone : Reactions are : CO + H2O CO2 + H2 – 326 K. Cal

C + CO2 2CO

Besides above reaction zones, there is an ash zone under the oxidation zone through which calculated quantity of air saturated with steam enters and receives heat from the ash, gets preheated and proceeds upwards to the oxidation zone. The ash on the other hand gets cooled down before it comes out to the ash pan. D) The distillation zone starts from the top of Secondary Reduction Zone & extends upward to about 2500 mm or so in which considerable quantity of volatile matter (about more than 75%) gets stripped and picked up by gas. At the top, there is preheating zone and above all there is drying zone.
