2. INTRODUCTION:
In this powerplant coal fossilfuel are used as fuel,from the combustion heat
Produced this heat is utilised in boiler to increase the pressure and tempereture
Of water which then fed to the turbine when the turbine rotates rotating
The turbine shaft then electricity generated
TWO TYPE:
1-CAPTIVE PP
2-CETRAL PP
CE-TE-ME-EE
Again steam pp are two type
1-condensing type
2-non condensing type

3. Eficiency of power plant:
1-THERMAL EFFICIENCY
2-ELETRICAL EFFICIENCY
3-OVER ALL EFFICIENCY
MERITS:
.Fuel used cheaper
.cheaper initial cost
.such plants can existed irrespective of existance of fuel
.can be located at load centers
DEMERITS:
.High mentainance and operating cost
.polluting environ ment
.huge requirment of water
.handling of coal disposal and ass
Is quite difficult

4. WORKING OF STEAM
POWER PLANT

9. The most important constituents of a steam power
station are:
a. Steam generating equipment
b. Condenser
c. Prime mover
d. Cooling towers
e. Electrical equipment
Steam generating equipment includes:
• Boiler
• Boiler furnace
• Superheater
• Economiser
• Air Pre-heater

18. AND ITS FUNCTIONS

19. Introduction:
• Particulate Collection Device used in
industries to minimize air pollution
• Principle of operation Electrostatic
attraction
• Efficiency of 99% in many industries
• Can handle large gas volumes with a wide
range of inlet temperatures, pressures, dust
volumes, and acid gas conditions
• Can collect particles of varying sizes in dry
and wet states

20. Theory of Precipitation:
 Theory of PrecipitationCharging, Collecting & Rapping
 Particle charging Discharge & Collection Electrodes
 Corona Discharge Avalanche Multiplication
 Ionization of gas molecules
 Particle Charging Mechanism Field charging, Diffusion
charging, Electron charging
 Particle Collection
 Particle Removal

21. Particle Charging:

22. Corona Discharge

23.  Ionization of Gas
Molecules
 Particle Charging
Field charging,
Diffusion charging,
Electron charging

24.  Particle collection
 Particle Removal by
rapping

26. Conclusion
 All ESPs, no matter how they are grouped, have
similar components and operate by charging
particles or liquid aerosols, collecting them, and
finally removing them from the ESP before
ultimate disposal in a landfill or reuse in the
industrial process
 The precipitator should be designed to provide
easy access to strategic points of the collector for
internal inspection of electrode alignment, for
maintenance, and for cleaning
electrodes, hoppers, and connecting flues during
outages
