CONTENTS
KSTPS has following important parts :- 1) Introduction3) Basic principle4) Plant overview5) Coal Handling Plant6) Boiler7) Economiser8) Air preheater9) Steam Turbine10) Generator 11) Ash Handling Plant12) Water treatment plant
INTRODUCTION
It was established in 1983It is located at the left bank of the CHAMBAL River at the upstream of KOTA BAIRAJ.
Produce electricity by coal . Having 7 units (presently) producing continuously
1st& 2nd units are of 110 MW each.3th ,4th & 5th units are of 210 MW.6th&7th units are of 195 MW Produce almost 1240 MW energy . Water supply from kota barrage.
BASIC PRINCIPLE
In thermal power plant heat energy of coal combustion converts into electrical energy.
This heat energy produced by burning the coal in a boiler is used to rise the steam
Steam produced is used to drive the turbine to which coupled the alternator.
Alternator convert mechanical energy into electrical energy.

OUTLINE LAYOUT
COAL HANDLING PLANT
Coal is suppliedThrough rail
Track by own trains
By wagon TriplerThe coal is drawn
Into underground hopper
By means of two Belts coal is transferred
To the Conveyer
Now coal is transferred toCrushing house and
stored to bunkers
Now coal is fed to Mills Where coal is
Crushed in pulverizedform
Coal is taken to Coal nozzle
In wind box assembly
From nozzle coal Is
discharged to furnace
BOILER
FUNCTION:- To generate steamIt is a closed vessel in which water under pressure is
converted into steam A boiler is always designed to absorb maximum amount of
heat released in process of combustionFURNACE:-It is primary part of boiler where the fuel is
Burnt to liberate the heat energyRAW MATERIAL USED :- Pulvarized coal COMBUSTION MEDIUM :- Air FANS :- FD Fan , ID Fan
Chemical energy of fuel
Thermal Energy bycombustion
ECONOMISER
Economizer is a device which recover the heat from the flue gases on their way to chimney
Its rise the temperature of feed water It increases the 10-12% efficiency of the plant
AIR PRE-HEATER Air pre-heater are employed to recover
the heat from the flue gases leaving the economiser super heater and economiser generally
cannot fully extract the heat from flue gases
STEAM TURBINE
It is convert stored energy in steam in to the mechanical energy
It is a machine in which shaft is rotated steadly by reaction of steam ,air upon blades of a wheel

TURBO GENERATOR An electrical generator is a machine which converts Mechanical energy into electrical energy.
Driven by directly coupled steam turbine at a speed of 3000 r.p.m.
Have two main parts:• Rotor• Stator
A temperature detector is provided to maintain the temperature.
Temperature of windings is maintain by hydrogen coolant.
ASH HANDLING PLANTMainly have 3 sub plants:
Air and Gas Plant.
Fuel and Ash Plant.
Ash Disposal and & Dust Collection Plant.
Hydraulic system is used for ash handling in KSTPS
In Yr. 2010-11 fly ash utilization is 97.31%
WATER TREATMENT PLANT
Water treatment plant are use for provide the pure and clean water
to the boiler. Because river water contain many suspended
impurities We are required some filter to remove this type
of impurities Carbone filter remove excess chlorine from
clarified water
