I have completed my summer training at BHEL power plant at Bawana. This plant is overhanded by BHEL northern region,It is design to produce the 1500 MW electricity for supply to the DELHI and DELHI -NCR.. plant is combined cycle gas power plant that is integrated to the heat power plant that is work on the Rankine cycle. i have train under experienced senior engineers.✌

4. INTRODUCTION TO ORGANISATION
BHEL , is the largest engineering and manufacturing enterprise in India with global
credentials.
More than 65% of the installed capacity for electrical power in India is contributed
by BHEL.
BHEL has carried out ‘System engineering’ and ‘Turnkey execution’ of projects not
only in India but also in other most countries.
BHEL’S products cater to the wide spectrum of customers in various fields like
power generation & transmission , oil exploration & production , transportation ,
steel & metals, fertilizers & petrochemicals, refineries, cement plant, heavy
engineering industries, non-conventional energy sources, defense equipment’s etc.

6. AUXILIARIES OF THE PLANT
AERATOR- This is the first stage in the treatment of water. In this the water is made
bacteria free.
Clarifier- It is basically the stage where sludge is removed from the water.
Cooling tower and auxiliary cooling tower:-
The main parts of the gas and the steam turbine are cooled through the main cooling.
These parts are cooled through the auxiliary cooling tower:-
Natural draft
Cross flow
Counter flow
Induced draft
Forced draft

7. COMBINE CYCLE

8. DESIGN PRINCIPLE OF COMBINE CYCLE
• Working principle of a
combined cycle
power plant
legends:- 1.electric generators
2.steam turbine
3.condenser
4.pump
5.boiler/heat exchanger
6.gas turbine

9. GAS TURBINE
• Also called a combustion turbine
• The gas turbine assembly contains 7 major section:-
Air intel system
Compressor
Fuel handling system
Combustion system
Turbine
Exhaust system
Lubricating oil

10. BRAYTON CYCLE
• Working process of Brayton cycle:-
Compressor
Combustor
Turbine
exhaust

11. ADVANTAGES OF GAS TURBINE ENGINES:-
• Smaller in size
• Fewer moving parts
• Reliability
• Waste heat is dissipated almost entirely in the
exhaust
• Low lubrication oil cost consumption
• High operating speed

12. DISADVANTAGES OF GAS TURBINE
ENGINES:-
• Cost is very high
• Less efficient at ideal speed
• Less responsive to change in power demand

13. STEAM TURBINE
• A steam turbine is a device that extracts thermal energy
from pressurized steam and uses it to mechanical work on
a rotating output shaft .
• It is used to drive an electrical generator.
• The ST includes
a) Condensing
b) Non-condensing
c) Reheat ,extraction

14. WORKING OF STEAM TURBINE
Steam turbine works on Rankine cycle.
Working process:-
 Process 1-2 (pump): water is pumped to achieve pressure head.
 Process 2-3 (boiler): water is heated in a boiler firstly to saturated liquid state after
that up to saturated vapour state and then to super heated state with the help of
different auxiliaries.
 Process 3-4 (turbine): isentropic expansion process in which thermal energy of steam
is converted into mechanical energy.
 Process 4-1 (condenser): heat rejection at constant temp and change of phase from
vapour to liquid .

15. WORKING OF STEAM TURBINE BASED ON RANKINE CYCLE

16. HRSG
• A HRSG is heat recovery steam generator
• An energy recovery heat exchanger
• The common application fot an HRSG
a) In a combined-cycle power station
b) In diesel engine combined cycle power plant
c) In cogeneration plant

17. BUSDUCT
• It is used carry voltage and current from transformer
to other components like generator and switchgear.

18. CIRCUIT BREAKERS
• A circuit breaker is automatically operated electrical switch
• It is design to protect an electrical circuit from damage
• Once a fault is detected, contacts within the circuit breaker
will open.
• Some mechanically-stored energy is used to separate the
contacts.
• Although some of the energy required may be obtained
from the fault current.
