This presentation provides an overview of power generation at NTPC's Anta power plant. It discusses the key components of a combined cycle power plant, including the gas turbine, waste heat recovery boiler, and steam turbine. It also explains the basic processes involved, such as the Brayton cycle for gas turbines and Rankine cycle for steam turbines. The presentation aims to educate about how NTPC generates reliable power through an efficient combined cycle process that integrates gas and steam turbines to maximize energy output.

9. Gas Turbine
• Gas Turbine is a heat engine, working on the air
standard Brayton cylcle. The process include :
1. Compressor
2. Combustion
3. Expansion

10. Gas Turbine Components
• Air intake system
• Compressor
• Combustion chamber
• Turbine
• generator
• Naphtha fuel system

12. Waste Heat Recovery Boiler
• Waste heat recovery boiler(WHRB)convert
waste heat into steam , which is non-fired, duel
pressure, and forced circulation type.
• Boiler has two different water/steam cycle
known as high pressure system and low
pressure system.

14. Steam Turbine
• Steam turbine process include:
Pressurization : pressurization of working medium
(water) by Boiler feed water pump.
Heating: phase change of working medium (from
water to heating) and superheating at constant
pressure in Boiler.
Expansion: Expansion of steam in the Turbine.
Condenstation : condenstation of steam by cooling
water.

15. COOLING TOWER
• Remove heat from the water discharge from the
condenser so that the water can be discharge to
the river or re-circulated and re-used.

17. VISSION and MISSION
VISSION :
To be the world’s largest and best power
producer.
MISSION :
Develop and provide reliable power.

18. CONCLUSION
I have studied about the power plant, specially in
ANTA. Studied about gas power plant, specially
natural gas could be use for power generation in gas
power plant. It is very economical but less efficient.
mainly methane (CH4) is used as fuel. It is very
profitable in case of pollution. It is very less polluted.
