INTRODUCTION

Coal/Lignite based Thermal Power Generation

has been backbone of power generation in India;

Coal is likely to remain the main fuel source for

the domestic energy market over the next fewdecades;

Indian coal is of low grade having high ash

content up to 40-45%;

Large quantity of ash is being generated at

Thermal Power Stations in the country.Cont.-

INTRODUCTION

Gainful utilization of ash in environment friendlymanner on continuous and sustainable basis isa matter of concern;

A large number of technologies have been

developed for gainful utilization and safemanagement of fly ash under efforts of Fly AshMission of GOI since 1994.

Fly ash has now been established as a

Resource Material and Useful Commodity. It has now become a saleable commodity.

PROGRESSIVE FLY ASH GENERATION & UTILIZATION

(During 1996-2011)

Fly ash utilization has increased from 9.63% in

1996-97 to the highest level of 62.60% in 2009-

10 and it was about 56% during 2010-11; Quantity wise, fly ash utilization has increased

from 6.64 million tonne in 1996-97 to maximum

Utilization of Flyash in Agriculture


21/24

21

CONCLUSION

We achieved the highest level of fly ashutilization of 63% in 2009-10 and it was about56% in 2010-11;

States and districts where thermal powerstations are located need to be sensitized to theneed for utilization of fly ash;

Use of fly ash in backfilling/stowing of closed/

abandoned/running open cast and undergroundmines has large potential for utilization of fly ash;

Cont.-

22

CONCLUSION

Use of fly ash in the construction of road

embankments/flyovers is gradually picking up.

However, its full potential is yet to be realized.

Use of fly ash in the construction of railwayembankments has potential for large scale

utilization of fly ash;

Cont.-


23/24

23

CONCLUSION

Use of fly ash based building materials, like fly

ash based bricks, blocks, tiles etc. by Govt.

agencies, both at Central and State level, is

required to be ensured.
