INTRODUCTION

3.  Dissolved salts and minerals in water can we removed
completely by a series of cation and anion exchangers.
Most of the steam generating plant use this process for
external treatment of feed water. Water treatment in this
method is done at demineralisation plant.
Collidal slica can not removed in DM plant .

4.  Un dissolved suspended impurities like-mud, sand,
sediment etc.
Dissolved salts and minerals, e.g. carbonate, bi-
carbonate, silicate, and nitrate, ca/mg.
Dissolved gases such as oxygen, carbon dioxide, etc.
Other materials, like acid, oil, etc.
Types of impurities in Water

5. River water contains insoluble or undissolved
Suspended matter like mud, sediment and sand.. The
Turbidity of this water is high.
UNDISSOLVED MATTER CAN BE REMOVED FROM
WATER FOLLOWING THREE METHAD-
Sedimentation
Filtration
Coagulation

Ultra filtration is very effective
filtration technology for the
separation , concentration and
purification with complete
removal of pathogenic bacteria
and suspended solid.

chloride, sulphate, nitrate, carbonate, bi-carbonates
and silicates these salts are having-
Cations like- Ca+, Mg+, Na+ etc.
Anions like-Co3-, So4-, Cl-, Sio3- etc.

12. Coal Handling Plant
Coal is the basic and the oldest raw
material used on large scale throughout the
world. Throughout history, coal has been a
useful resource. It is primarily burned for
the production of electricity and/or heat is
also used for industrial purposes, such as
refining metals. A fossil fuel, coal forms
when dead plant matter is converted into
peat, which in turn is converted into
lignite, then sub bituminous coal, and
lastly anthracite. This involves biological
and geological processes that take place
over a long period.

16. WATER AND STERAM CIRCUIT

17. Boiler is a closed vessel having minimum capacity of 22.75 L along
with the mountings in which water or other fluid is heated. The
heated or vaporized fluid exits the boiler for use in various
processes or heating applications, including boiler-based power
generation, cooking.

19. The steam turbine is a prime-mover in which the
potential energy of the steam in transformed into kinetic
energy, and latter in its turn is transformed into the
mechanical energy of rotation of the turbine shaft. The
turbine shaft, directly or with the help of a reduction
gearing, is connected with rotor of generator.
Classification of Turbines:
The steam turbines are mainly divided into two groups as –
1-water turbine
2-wind turbine
3-steam turbine
 impulse turbine

22. FANS ARE USED
IN POWER PLANT
 ID FAN-This fan is used to create negative pressure
in the furnace.
 FD FAN-Forced draft fans is to provide a positive
pressure to a system.

23.  Steam after rotating
steam turbine comes to
condenser. Condenser
refers here to the shell
and tube heat
exchanger (or surface
condenser) installed at
the outlet of every
steam turbine in
Thermal power stations
of utility companies
generally.
CONDENSER

24. The main purposes of the condenser are to condense the
exhaust steam from the turbine for reuse in the cycle .
Increased plant efficiency .
Reduced steam flow It is therefore very advantageous to
operate the condenser at the lowest possible pressure.
CONDENSER
Purpose of condenser :

25. CONDENSER
Function of condenser :
Function of the condenser is to create a vacuum by
condensing steam.
 for re-use as the feed water supply to the steam
generator.

26. CONDENSER
Operation of condenser :
The main heat transfer mechanisms in a surface condenser are the
condensing of saturated steam on the outside of the tubes and the
heating of the circulating water inside the tubes.
 Thus for a given circulating water flow rate, the water inlet
temperature to the condenser determines the operating pressure of the
condenser.
As this temperature is decreased, the condenser pressure will also
decrease.
 As described above, this decrease in the pressure will increase the
plant output and efficiency.
Due to the fact that a surface condenser operates under vacuum,
noncondensable gases will migrate towards the condenser.

27. Air Cooled Condenser
CONDENSER
Air Cooled condenser :
Air cooled condenser belong to the dry
cooling system. In direct dry cooling
steam from the steam turbine passes
through air cooled fin tube.

31. Ash Handling Plant
 What is Ash Handling?
Ash handling refers to the method of
collection, conveying, interim storage
and load out of various types of ash
residue left over from solid fuel
combustion processes
Ash Handling Plant I CPP I and III are
of great importance because the fly
ash which is collected through the
hoppers of ESP is used as a major
ingredient in the cement at the Jaypee
Rewa Cement Plant.
Fly Ash Silo

32. Fly Ash
fly ash :-Ash generated in the ESP which got carried out with the
flue gas is generally called Fly Ash. It also consists of Air Pre heater
ash & Economizer ash (it is about 2% of the total ash content).

•Fly ash handling system:
Fly ash is considered to be collected in ESP hoppers. Fly ashes from
ESP hoppers, extracted by vacuum pumps, fly up to intermediate
surge hopper cum bag filter for further dry conveying to fly ash silo.

35. •Bottom Ash Handling System: Bottom ash resulting
from the combustion of coal in the boiler shall fall into the
over ground, refractory lined, double V section type bottom
ash hopper having a hold up volume to store bottom ash and
economizer ash of maximum allowable condition with the
rate specified. The slurry formed shall be transported to
slurry pump through pipes.
