This document provides an overview of Shree Cement Ltd.'s coal-fired power plant and efforts to reduce its environmental impact. It discusses the company's history and various units. It then describes how a coal-fired power plant works and its pollution impacts. The document introduces electrostatic precipitators that use high voltage to charge and capture particulate matter from flue gases. It discusses using fly ash from the plant in construction and the flue gas desulfurization system to reduce SO2 emissions and produce gypsum.

4. Introduction
 SHREE CEMENT started its journey in the year 19
85 with our first plant of 0.6 MTPA at Beawar. Sin
ce then it has grown to become a multi-unit, multi
-location and the largest cement producer in north
ern India with a total capacity of 6.8 MTPA.
 Shree Cement Limited Registered office & Works i
s located at Beawar (Raj.) & corporate office at Ko
lkata.
 SHREE CEMENT LIMITED is an energy conscious &
environment friendly business organization. Havin
g ten Directors on its board under the chairmanshi
p of Shri B.G. Bangur.

5. COAL FIRED POWER PLANT
 A coal fired power station is a type of ther
mal power station that produces electricity,
by burning coal to boil water, producing st
eam which drives a steam turbine, which
turns an electric generator.

7. ENVIRONMENTAL IMPACTS
 A coal plant is the main source of air pollution due
to emission of mainly CO2, SO2, & NO2.
 Due to emission of such gases the rate of green hou
se effect is increasing day by day that leads to globa
l warming.
 The coal plant waste is more radioactive than a nucl
ear waste so it causes radiation.

8. ENVIRONMENTAL IMPACTS
(Cont…)
 Coal burning leads to origination of met
hyl mercury that is toxic in nature and h
armful to those who eat freshwater fish.
 It causes Acid Mine Drainage under whic
h pyrite over exposed coal surfaces whe
n comes in contact with water and air th
en it forms sulfuric acid and pollute the
water

9. E.S.P. AN INTRODUCTION
 MAIN ACCESSORIES:
• Collecting plates:
• Discharge electrode:

10. E.S.P AS ECOFRIENDLY TOOL
 First of all high DC voltage is applied to
the discharge electrodes by transformer
- rectifier set. This results in to corona f
ormation around the electrode.
 When ash particles comes in contact wit
h this corona they get charged, usually
with negative polarity.

11. E.S.P AS ECOFRIENDLY TOOL
(Cont…)
 As the collecting plates are positively ch
arged so negatively charged particles wil
l migrate towards the collecting plates.
 Then these plates are hammered via rap
ping system, and particulate get collecte
d in the hoppers.
 This result in to ash free flue gas.

14. USE OF FLY ASH
 Fly ash is useful for making bricks, tiles
and blocks etc.
 It is also useful in making cement.
 Fly ash can also be used in road constru
ction, plastering on buildings, agriculture
, irrigation etc.

15. SOME OTHER ALTERNATIVES
 F.G.D.(Flue gas desulphurization):
This plant basically converts the SO2 i
n to gypsum by some chemical processe
s, this gypsum is then used with in the c
ement as setting agent.

16. FLUE GAS DESULPHURIZATION

17. SOME OTHER ALTERNATIVES (CO
NT…)
 Fabric filters(bag house):
Gases with dust particles when enter i
n to the bag house and pass through fab
ric bags that act as filters and filtered ou
t and the dust is then collected in to the
hoppers.

18. SOME OTHER ALTERNATIVES (Co
nt…)
Fresh air
Dusty air
Fabric bags
Dust
