6. Coal Handling Plant Section
 Wagon Unloading System
 Crushing System
 Conyeing System

7. Wagon Unloading System
Unload the coal
from wagon to
hopper with the help of
wagon tippler
Hopper allow to
pass coal peaces
<200mm
From hopper coal
fall on vibrator
which is supported
by roller

8. Crushing System
Crusher house :- It Consists
of crushers which are used to
crush the coal to 20 mm size
Two types
 *Primary crusher
1. Rail crusher
2. Rotary Breaker
 *Secondary crusher

9. Conveying System
 Belt are used to convey coal
from coal handling plant to
furnace
Specification:-
 Belt Width:- 1400mm
 Speed :- 2.2 m/sec
 Total Install power:-360kw
 Capacity :- 1350/750 ton/hr
 No. of conveyor :- 38 Figure 5:- Conveying System

10. Boiler
 A closed vessel where water under pressure is converted into steam.
 Hot water or steam is used to transfer heat to a process.
 Always designed to absorb the maximum amount of
heat released during combustion
Furnace: The primary part of the boiler where fuel is burned to liberate
heat energy.
 Energy conversion
 Chemical Energy of fuel → Thermal Energy by combustion

11. Figure 6:- Boiler

12. Super-heater
Consists of a group of tubes.
These tubes are heated by the hot combustion gases as they pass from
the furnace to the chimney, which increases the temperature of the
steam.
The primary function of the super-heater is to remove moisture from
the steam leaving the boiler tubes.
 A component that increases the temperature of steam, making it superheated,
by utilizing heat from the hot flue gases.
 This process enhances the efficiency of the steam turbine and reduces the risk
of condensation within the turbine, preventing potential damage.

13. Steam Turbine
 It is a machine in which a
shaft
is rotated steadily by reaction
of
steam, air upon blades of a
wheel.
 When steam is used then it is
called steam turbine.
 It works on Modified
Rankine cycle.

14. Economizer
• Economizer is a device which recover heat from the flue gases on
their way to chimney.
• It increase the 10-12% efficiency of the plant.

15. Electrical Generator
 An electrical generator is a
machine which converts
mechanical energy into electrical
energy through electro
mechanical energy conversion.
The generator is driven by
directly coupled steam turbine at
a speed of 3000 r.p.m.

16. Water Treatment Plant
 Pressure Filter: Removes "undissloved impurities" from raw water. This
suggests a general filtration step for larger particles or suspended solids.
 Carbon Filter: Removes excess chlorine from clarified water. Chlorine is often
used as a disinfectant but can be corrosive or problematic in certain industrial
processes.
 D.M. Plant (Demineralization Plant): Removes dissolved impurities from
clarified water. This is a crucial step for producing high-purity water by
removing ions and minerals.
 Water Quality Monitoring: The conductivity, pH, and silica content of the
treated water must be checked regularly. These parameters are critical for
preventing scaling, corrosion, and other issues in systems like boilers.

17. Cooling System
 Hydrogen Cooling in KSTPS: In KSTPS , a hydrogen cooling system is
used for generator cooling.
 Reasons for Hydrogen Cooling: Hydrogen is preferred due to its
superior cooling properties and low density. It's noted that the thermal
conductivity of hydrogen (H2​
) is 7.3 times that of air, making it a much more
efficient cooling medium.
 Seal Oil System: A seal oil system is employed in the turbine for less
friction in the bearings. This system ensures smooth operation and reduces
wear in critical rotating components.
 Water Cooling for Fire: Water cooling is also used as a measure for any
kind of fire, indicating its role in fire suppression or prevention within the
plant.

18. Ash Handling Plant
 Subdivision of a Plant The plant can be subdivided into 3 sub-plants:
1) Fuel and ash plant: Handles the incoming fuel and the initial stages of ash.
2) Air and Gas plant: Manages the air supply for combustion and the exhaust
gases.
3) Ash disposal and dust collection plant: Deals with the collection and disposal
of ash and dust.
 Ash Composition in Thermal Plants
In thermal plants, 25% of the ash is furnace bottom ash, and 75% is pulverized
fuel ash (also known as fly ash).
Fly Ash Removal
An Electrostatic Precipitator is used in the ash handling plant to remove fly ash.
This device is crucial for environmental control, capturing fine particulate matter
