PRESENTED BY : SUBMITTED TO : MOHD SHOAIB NUPUR MEHTA ROLL NO.-1351540015 (ASST. PROF. ME DEPT.) (MECHANICAL FINAL YEAR)

ABOUT NTPC• NTPC is the largest power generating company in india,

was set up in 1975 to accelerate power development in the country.

• NTPC has installed capacity of (43803 MW).

• NTPC has 16 coal based power stations (31182 MW).

• NTPC has 7 gas based power stations (4017 MW).

• NTPC has 7 power stations in joint ventures (8604 MW).

• In 1997 , Government of india granted NTPC status of ‘Navratna’.

ABOUT NTPC, TANDA

• Tanda Thermal Power Station is located in Ambedkar Nagar district in the Indian state of Uttar Pradesh. The power plant is one of the coal based power plants of NTPC.

• In the year 2000, Uttar Pradesh State Electricity Board (U.P.S.E.B.) transferred Tanda Thermal Power Plant to NTPC Limited against payment overdue.

• After that this plant, because of the better maintenance by NTPC Limited, this power plant has crossed its Plant Load Factor (P.L.F.) to more than 100%.

OPERATION OF THERMALPOWER PLANT

MAIN DEPARTMENTS OF PLANT•Coal handling plant•Boiler•Superheater •Turbine•Generator•Condenser•Cooling Tower

COAL HANDLING PLANT

• The function of coal handling plant is automatic feeding of coal to the boiler furnace.

• A thermal power plant burns enormous amounts of coal.

• A 200MW plant may require around 2000 tons of coal daily

• following are the process of plant-:

1. Bunkering process2. Unloading process3. Feeding process 4. Screening process5. Crushing process

•A boiler or steam generator is a closed vessel to which water under pressure, is converted into steam.

•It is one of the major components of a thermal power plant.

•Always designed to absorb maximum amount of heat released in the process of combustion.

BOILER

SUPER HEATER

•A device which moves last traces of moisture.

•It helps in reduction in requirement of steam quantity.

•Steam being dry reduces the mechanical resistance of turbine.

•No corrosion at the Turbine blades.

TURBINE •A steam turbine converts heat energy of steam into mechanical energy and drives the generator.• It uses the principle that steam when issuing from a small opening attains a high velocity.

•This velocity attained during expansion depends on the initial and final heat content of the steam.

•This difference b/w initial and final heat content represents the heat energy converted into kinetic energy.

•These are of two types :- 1. Impulse turbine2. Reaction turbine

GENERATOR

•The Synchronus Generator is used to generate power by connecting the shaft of the Turbine to the shaft of the generator which create the magnetic flux producing Emf.

•The generated voltage will generally 33 KV to 11 KV max.

• the generated Voltage is stepped up by connecting Step up transformer and is also used for auxilliary purpose.

CONDENSER• Which condenses the

steam at the exhaust of turbine.

• It creates a very low pressure at the exhaust of turbine, this helps in converting heat energy of steam into mechanical energy in the prime mover.

• The condensed steam can be used as feed water to the boiler.

COOLING TOWER• Remove heat from the water

discharged from the condenser so that the water can be discharged to the river or re circulated and reused.

• Air can be circulated in the cooling towers through natural draft and mechanical draft.

UTILISATION OF SECONDARY RAW MATERIAL

(ASH)• Construction of embankments and fills

• Construction of road in sub-base

• Manufacture of cement

• Manufacture of bricks/blocks

• Filling as flowable fill material

• Agriculture as soil amendment/source of essential plant nutrients

ADVANTAGES

•The fuel used is quite cheap.

•Less initial cost as compared to other generating plants.

•It can be installed at any place irrespective of the existence of coal.

•The coal can be easily transported to the site

•It require less space as compared to Hydro power plants.

•Cost of generation is less than that of diesel power plants.

DISADVANTAGES

•It pollutes the atmosphere due to production of large amount of smoke and fumes.

•It is costlier in running cost as compared to Hydro electric plants.

•Maintenance cost is more.
