WATER:-
The source of water for power station is reservoir formed by
Kota Barrage on the Chambal River.
General Layout & Basic Idea The Kota Thermal Power Station
is divided into four main circuits : 1.Fuel and Ash Circuit. 2 .Air
and Gas Circuit. 3.Feed water and Steam Circuit. 4.Cooling Water
Circuit.
A control system of station basically works on Rankin Cycle.

COAL HANDLING PLANT
It can be called the heart of thermal power plant because it
provided the fuel for combustion in boiler. 1.Northern Coal Fields
Limited(NCL), 2.South Eastern Coal Fields Limited(SECL)
Coal India limited is supply coal from its coal mines of coal
producing subsidiaries SECL & NCL to KSTPS through railway
wagons.
Everyday 6 to 7 trains of coal are unloaded at KSTPS.
The approximate per day consumption at KSTPS is about 18000
metric tones.
Coal handling plant
coal is transported to the power station by road and rail and is
stored in the coal storage plantThe pulverized coal is fed to the
boiler by conveyor beltsFrom the coal storage plant, coal is
delivered to the coal handling plant where it is pulverized
Wagon unloading system
Unload the coal from wagon to hopper with the help of wagon
Tripler.
Conveyor Belt
Belt are used to convey coal from coal handling plant to
furnace.
(b) ASH HANDLING PLANT
This plant can be divided into 3 sub plants as follows:-
1)Fuel and Ash Plant.
2)Air and Gas Plant.
3)Ash Disposal and & Dust Collection Plant
USES ASH:
1.Manufacturing of building materials. 2.Making of concrete.
3.Manufacturing of pozzuolana cement. 4. Road construction
(C). ELECTRO-STATIC PRECIPITATOR
As far as air pollution is concerned now a days various flue
gases filter are there in service. These filters are E.S.P. Fabric
filter high efficiency cyclone separations and sitelling room.
where the particle size vary from 0.75 microns to 100 micron use
gradually use E.S.P. to purify the flue gases due to its higher
efficiency & low running cost etc.
STEAM TURBINE
.TECHNICAL DATA OF TURBINES :-The main technical data of 110 MW
turbine is given below:-Rated output. : 110 MW.Economic output : 95
MW.Rated speed. : 3000 rpm Direction of rotation viewing from :

TYPES OF TURBINE
It convert heat energy of steam into mechanical energy and drive
generator.
It uses the principle the steam when issuing from a small
opening attains a high velocity.
6.TURBO GENERATOR THEORY :-
TURBO GENERATOR manufactured by B.H.E.L.
The generator stator is a tight construction, supporting &
enclosing the stator windings, core and hydrogen coolers.
The generator is driven by directly coupled steam turbine at a
speed of 3000 r. p. m. the Generator is designed for continuous
operation at the rated output.
The source of excitation of rotor windings is thyristor
controlled D.C. supply.
TECHNICAL DATA:-
Generator (110 MW):- Type : t.g.p. 2,34,602 Continuous apparent
power : 1,37,500 KVA. Active power : 7,10,000 KW. Power factor :
0.8 (lagging). Rated voltage : 1000 + 5% rated. Current : 7,220 A
Critical speed : 3000 r. p. m. at frequency : 50 Hz. Phase
connection : double star. No. of terminals : 6. Main diameter of
slip rings : 420 mm. Voltage regulation : 39%. Reactance :

TURBO GENERATOR PICTURE
TRANSFORMER
Transformer is a static device which is used to change the
voltage level keeping the power and frequency same. In the plant
transformer is one of the most important equipment. It is located
in between the main plant and the switchyard.
GENERATOR TRANSFORMER (GT A):-It steps up the voltage from 16.5
KV to 220 KV. It connects the plant with the 220 KV switchyard.
GENERATOR TRANSFORMER (GT B):-It steps up the voltage from 16.5
KV to 400 KV. It connects the plant with the 400 KV switchyard.
STATION TRANSFORMER (ST):-It is a step down transformer with 50
MVA capacities. It is used to step down 220 KV from the grid to 6.9
KV.
AUXILIARY TRANSFORMER (UAT):-It is a step down transformer with
20 MVA capacities. It steps down the voltage from 16.5 KV to 6.9
KV. STATION SERVICE TRANSFORMER (SST):-It is a step down
transformer with 2MVA capacity. It is used to step down from 6.6 KV
to 0.4333 KV. UNIT SERVICE TRANSFORMER (UST):-It is a step down
transformer with 2 MVA capacity. It is used to step down from 6.6
kV to 0.4333 KV.
