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
