Energy is a driving force behind rapid economic growth of the country.

India ranks tenth in the world in total energy consumption.

The pattern of energy production put coal and oil again on top. These account for 65% of the entire generation.

Renewable energy ranks bottom of the total production just before the Nuclear energy.

The distribution of energy resource like hydro power is skewed towards North-eastern states of the country as 70 % of the total hydro potential is located in the Northern and North-eastern region.

Power Consumption In India

PTPP is third ranking power project of U.P.

PTPP is a Power Generation Station where power is generated via

steam operation on Turbine.

Steam is Generated by Coal Firing.

It is Located about 26 kms away from Jhansi Railway Station with

Parichha Dam beside it.

Two units of 110 MW, two of 210 MW and two of 250 MW , with

overall generating capacity of 1140 MW.

Auxiliaries and Instruments are imported from BHEL, KOTA COMPANY

and Steel is imported from SAIL & TISCO.

STEAM GENERATOR AND AUXILIARY SYSTEM

Steam generator is a device which converts water into steam.

This unit produces superheated steam at almost constant temperature of 810 kelvin.

For getting high temperature, water and air is heated in multistage process with a complex designed steam generator.

Auxiliary system contains Primary Air Fan, Air Pre Heater, Mills ,Economizer ,De-aerator ,Furnace ,Boiler Drum ,Super Heater ,Re-heater ,ESP.

FUEL HANDLING SYSTEM

Coal is conveyed through

rail wagon from out side

of plant and through

conveyor system

collected in hopper and

ground to a very fine

powder by large metal

spheres in the pulverized

fuel mill.

FEED WATER SYSTEM

• This system deals with how the working fluid is transferred to water

drum.

• Before it water is de-aerated in de-aerator and gets some heat

extracted from steam.

• Circulation of feed water takes place via BOILER FEED PUMP to water

drum.

• Feed water system has three segments as Feed Water Heater, Boiler

Feed Pump and Feed Water Supply.

WATER CONDITIONING SYSTEM

•Natural occurring waters, whether surface or well water, contain

dissolved and suspended impurities.

•Impurities may be injurious to steam boiler operation and cooling water

service.

•Fresh water in cooling tower requires little and in boiler possibly, no pre-

treatment.

•Water conditioning system is used to purify raw water to required

quality for all phases of operation.

SWITCHYARDA switchyard is a part of an electrical transformation, transmission,system. Switchyard transform voltage from high to low,or the reverse, or perform any of several other important functions.

STEAM TURBINE BASED COAL FIRED THERMAL POWER GENERATION

Ash Handling System• The percentage of ash in coal varies from 5% in good quality

coal to about 40% in poor quality coal• Power plants generally use poor quality of coal , thus

amount of ash produced by it is pretty large• A modern 2000MW plant produces about 5000 tons of ash

daily• The stations use some conveyor arrangement to carry ash to

dump sites directly or for carrying and loading it to trucks and wagons which transport it to the site of disposal

Basically Current Transformer(C.T.),Voltage Transformer (V.T.) and

Generating transformer.

C.T. is essentially a step up transformer which step up the current to a

known ratio.

Designed to provide a current in its secondary winding proportional

to the alternating current flowing in its primary.

V.T. is essentially a step down transformer and it step downs the

voltage to a known ratio.
