BSL - Thermal power station
REASON FOR CHOOSING BHILWARA FOR THERMAL
POWER PLANT SETUP Availability of large amount of clean water from Kothari River required for the station.
Location of station on broad gauge main Hamirgarh Railway line.
Requirement of load in Bhilwara.
Constant power supply.
Proximity to M.P. Coal fields.
Transmission and Grid substation are quite nearer to the
site.
INTRODUCTION
B.S.L-T.P.S is coal based power plant in Bhilwara.
It is located ideally on the left bank of Kothari River
near Bhilwara.
Its has 2 units of capacity 10 MW and 6 MW, which
were synchronized in 1999.
It is one of the highest power generating plant in
Bhilwara with installed capacity of 16 MW.
CONTENTS OF THE PRESENTATION
• GENERAL LAYOUT
• COAL HANDLING PLANT
• PROCESS OF STEAM GENERATION
• TURBINE
• GENERATOR
• SWITCHYARD
COAL HANDLING PLANT
• Is called the HEART of thermal power plant because it provided the fuel for combustion in boiler.
• The coal is brought to the BSL-TPS from BHARAT COAL LTD.
• There are 3 tracks for transportation.
• Everyday multiple trains of coal are unloaded.
• Coal is unloaded from wagons by means of WAGON TRIPPLER
Bunkers Crusher house Conveyor
Row coal feeders
Coal mills(pulverization
)
BOILER FURNACETANGENTIAL FIRING OF PULVERISED COAL
OVERVIEW OF COAL HANDLING PLANT
Row coal from Bharat coal ltd. Dhanbad &
bilaspur(MP)
To B.S.L-T.P.S from gurla via a single railway track
Wagon trippler
CONVEYING SYSTEM
Coal size reduced by 20 mm
TURBINE
• Turbine is a machine in which a shaft is rotated steadily by impact of steam it converts heat energy into mechanical energy.

SWITCHYARD
The 220 KV Switch yard is the main part of the KTPS it has two buses arrangement with a bus coupled breaker.
There are 11 feeders connected at 220 KV switchyard
Main parts of Switchyard
• CIRCUIT BREAKER
• ISOLATOR
• CURRENT TRANSFORMER
• POTENTIAL TRANSFORMER
• LIGHTNING ARRESTOR
CIRCUIT BREAKER
Circuit breaker is basically a mechanical device used to make or break an electrical circuit under normal & abnormal condition.
A circuit breaker is switched on or off under load conditions an arc is produced in between the breaker contacts.
This arc produced between the breaker contacts is quenching by some suitable medium.
ISOLATORS & ARRESTORS
• Isolators are device which disconnect the instruments from power supply, the isolators provided at 220 KV switchyard are motor operated.
• Lightening Arresters are used in switchyard for preventing from Lightening phenomena and are installed at entrance of switchyard.
CURRENT TRANSFORMER
• Current transformers are provided for measuring and protection. All Current Transformers at 220 KV switchyard are BHEL manufactured .
• Designed to provide a current in its secondary coil proportional to current flowing in its primary coil.
• Primary winding consists of very few turns.
• Secondary winding consists of large no. of turns
• Current to be measured is passes through primary winding.
.
POTENTIAL TRANSFORMER
• Used for the measurement of high voltages.
• Primary winding is connected to voltage to be measured.
• Voltmeter is connected across the secondary winding.
