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.
Parichha Thermal Power Plant(PTPP)

Basic units of a thermal power plant:- Steam generator and auxiliary system.
Fuel Handling and Storage system.
Feed water system.
Water conditioning system.
Ash Handling System.
Thermal Power Plant
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
collected in hopper and
ground to a very fine
powder by large metal
spheres in the pulverized
Coal Hopper Pulverized Mill
FEED WATER SYSTEM
• This system deals with how the working fluid is transferred to water
• 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
• 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
•Fresh water in cooling tower requires little and in boiler possibly, no pre-
•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.
OUTDOOR EQUIPMENTS:-• Bus Bar• Lightening Arrester • Breaker• Capacitive Voltage Transformer• Earthing Rod• Current Transformer INDOOR EQUIPMENTS:-• Relays• Control Panels• Circuit Breakers
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
C.T. is essentially a step up transformer which step up the current to a
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.
