3. Introduction of company NATIONAL THERMAL POWER CORPORATION(NTPC). NTPC limited is the largest power generating company in INDIA. A public sector company, it was incorporated in the year 1975. It has an electric power generating capacity of 34,754MW. It is one of the seven maharatna companies. 3

4. CONT......... There are four main parts of NTPC : Combine Cycle Gas Turbine Waste Heat Recovery Boiler Steam Turbine 4

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. 12

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. 14

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 . 15

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

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. 18
